Melaleuca fulgens was introduced into cultivation in the United Kingdom in 1803 and is commonly grown in Australian gardens, with several hybrids also available. It is readily grown given sufficient moisture but needs good drainage as it is susceptible to fungal disease. Its attractive grey foliage and bright showy flowers are its horticultural features. Light pruning improves flowering and improves the shrub's shape.

The tiny leaves, shiny red new growth and feathery flowers of this verticordia have been described as "attractive" features and the plant has been cultivated since 1991. Propagation has usually been from cuttings and the plants have established in sand with gravel in full sun. They are relatively drought and frost hardy as well as resistant to the fungal disease that affect some other eremophilas.

Leucostoma canker is a fungal disease that can kill stone fruit (Prunus spp.). The disease is caused by the plant pathogens Leucostoma persoonii and Leucostoma cinctum (teleomorph) and Cytospora leucostoma and Cytospora cincta (anamorphs). The disease can have a variety of signs and symptoms depending on the part of the tree infected. One of the most lethal symptoms of the disease are the Leucostoma cankers.

Paspalum ergot is a fungal disease to which kodo millet is susceptible. Hardened masses of this fungus, called sclerotia, will grow in place of the millet grain. These compact fungi growths contain a chemical compound that is poisonous to humans and livestock if consumed, and potentially fatal. It causes damage to the central nervous system, causing excitability in animals and eventually loss of muscle control.

Some of the most important zoonoses are parasitic. Zoonotic intestinal parasites transmitted through contact with feces include Toxocara canis (the canine roundworm), which causes toxocariasis, visceral larva migrans, and ocular larva migrans, and hookworms, which can cause cutaneous larva migrans. Zoonotic skin parasites include scabies, caused by the mite Sarcoptes scabiei. The most common zoonotic fungal disease is ringworm, caused in this case by Microsporum canis.

Mycosis fungoides was first described in 1806 by French dermatologist Jean-Louis-Marc Alibert. The name mycosis fungoides is very misleading—it loosely means "mushroom-like fungal disease". The disease, however, is not a fungal infection but rather a type of non-Hodgkin's lymphoma. It was so named because Alibert described the skin tumors of a severe case as having a mushroom-like appearance.

In the same way that allelopathic properties of cover crops can suppress weeds, they can also break disease cycles and reduce populations of bacterial and fungal diseases, and parasitic nematodes. Species in the family Brassicaceae, such as mustards, have been widely shown to suppress fungal disease populations through the release of naturally occurring toxic chemicals during the degradation of glucosinolade compounds in their plant cell tissues.

The medium/soil is not critical as long as the soil is light as well as lightly firmed down but not heavily compacted. Sterilized potting soil will minimize problems with Botrytis or Pythium fungal disease. These problems are much more likely to occur if air circulation is poor. Most seeds need only be planted at a depth equal to their own thickness in order to germinate.

They are fungal diseases that can infect different parts of the host plants (i.e. leaves, stems, flowers) and usually create black spores called teliospores in the infected area. Teliospores produce sporidia, white smut, and can survive under harsh environmental conditions. Therefore, the most effective way to prevent the spread of this fungal disease is to remove and destroy the infected area of the plant.

US Fish and Wildlife Service, Atlanta, Ga. 12pp. Researchers have suggested the fungal disease chytridiomycosis, in combination with climate change, as a likely cause of the species' decline. However, since no direct link has been found, and not all species are affected by the fungus, the causes for the decline are still not clear. Habitat loss to homes and agriculture is the major ongoing threat.

The aphids can be a vector for cypress canker, a fungal disease that can cause die-back and death of cypress trees. One species particularly susceptible to damage by the aphids is Cupressus lusitanica, which is widely grown in Kenya as a plantation crop. Natural enemies of the aphid include parasitoid wasps in the genus Pauesia, and some of these have been considered for use in biological pest control.

Another study found that dry conditions added an average 25 days to the lifespan of infected individuals, while higher temperatures only added 4 days. Not only do these frogs face the threat of the fungal disease, but they also are threatened by human development. As trees are cleared for housing and urbanization, the habitat of A. zeteki is destroyed. Other threats include encroachment by agriculture, pollution, pet trade, and aquaculture.

Some plants have been seen succumbing to scale insects and fungal disease. Plants also have to compete with introduced grasses which smother them as seedlings, and with introduced shrubs such as boxthorn (Lycium ferocissimum). Open agricultural land is a poor habitat for shrubby tororaro, but is suitable for the other scrambling and climbing members of the genus (M. complexa and M. australis) which both compete with and hybridise with M. astonii.

Like most amphibians globally, the Ozark hellbender is at risk of chytridiomycosis, a very infectious amphibian fungal disease. It has been detected in all but two rivers C. a. bishopi is currently found in. Additionally, unusual physical abnormalities have been observed in Ozark hellbenders in recent years, such as missing limbs or eyes and epidermal lesions, with increasing frequency, although the cause of these deformities is currently unknown.

In 1869, the coffee industry was still thriving in Ceylon, but shortly afterwards, coffee plantations were devastated by the fungal disease Hemileia vastatrix, also known as coffee leaf rust (CLR), affecting not only Sri Lanka but other areas in Asia over the next 20 years. The planters nicknamed the disease "Devastating Emily". Production dipped rapidly and by 1900, coffee was only being cultivated on and was replaced by tea.

Aspen trunk rot is a fungal disease that causes stem decay heart rot of living aspen trees. The pathogen that causes this disease is the fungus Phellinus tremulae. Most of the symptoms of this disease are internal, with the only external signs of a diseased aspen being fruiting bodies called conks. A single conk found on an aspen can indicate advanced decay of up 82% of the tree volume.

Allen's major contribution to the study of fungi is through the field of plant pathology. Her work on the cytology of the rust fungus Puccinia graminis helped to elucidate the life cycle and pathology of this devastating fungal disease agent of cereal crops. This species has several formae speciales, variations that utilize specific host plants but have identical morphology (Schumann and Leonard, 2000). The life cycle of Puccinia graminis f. sp.

As of 2018, it is listed as a vulnerable species by the IUCN. In 2008, however, it was considered a least-concern species, which is the IUCN's lowest conservation priority. In the time between the two assessments, the fungal disease white-nose syndrome became widespread in eastern North America, severely impacting the tricolored bat. Historically, it was one of the most common bat species of eastern North America.

Coccidioides is a genus of dimorphic ascomycetes in the family Onygenaceae. Member species are the cause of coccidioidomycosis, also known as San Joaquin Valley fever, an infectious fungal disease largely confined to the Western Hemisphere and endemic in the Southwestern United States. The host acquires the disease by respiratory inhalation of spores disseminated in their natural habitat. The causative agents of coccidioidomycosis are Coccidioides immitis and Coccidioides posadasii.

Frog populations have declined significantly since the 1950s. More than one third of species are considered to be threatened with extinction and over 120 are believed to have become extinct since the 1980s. The number of malformations among frogs is on the rise and an emerging fungal disease, chytridiomycosis, has spread around the world. Conservation biologists are working to understand the causes of these problems and to resolve them.

Infrequent fires since European settlement have resulted in tall grass trees with full skirts. Mature grass trees have been found to be sensitive to fire, with high mortality rates occurring after controlled fuel reduction burns. They have also been found to be susceptible to Phytophthora cinnamomi, a fungal disease which causes die-back in native plants and is present in the park. Seedlings germinate in shady, moss covered sites under Brachyloma daphnoides (Daphne heath).

However, the fig breeding program was ultimately closed in the 1980s. Due to insect and fungal disease pressure in both dried and fresh figs, the breeding program was revived in 1989 by James Doyle and Louise Ferguson using the germplasm established at UC Riverside by Ira Condit and William Storey. Crosses were made and two new varieties are now in production in California: the public variety "Sierra", and the patented variety "Sequoia".

Hymenoscyphus fraxineus is a fungal disease that attacks ash trees. The disease causes leaf loss, crown dieback, and lesions in the bark. This fungus is, for the most part, fatal, both directly and indirectly, by weakening the tree's immune system so that it is more susceptible to attacks from pests or pathogens. Because of this, younger trees are more affected, and fully mature ash trees are incapable of living long enough to reproduce.

Pecan anthracnose is a fungal disease of pecan trees caused by the ascomycete Glomerella cingulata (Stoneman) Spauld. & H. It is a widespread disease found wherever pecan trees are grown. Pecan anthracnose has been reported as far back in time as 1914 (Rand 1914), and as far away as Argentina (Mantz, Minhot et al. 2010). Glomerella cingulata has two anamorphs which cause disease on pecan trees, Colletotrichum gloeosporioides and Colletotrichum acutatum (Latham 1995).

These areas prohibit the cutting or gathering of wood. Clark's nutcrackers pluck P. longaeva seeds out of the opening cones. The nutcrackers use the seeds as a food resource, storing many for later use in the ground, and some of these stored seeds are not used and are able to grow into new plants. An introduced fungal disease known as white pine blister rust (Cronartium ribicola) is believed to affect some individuals.

Following in his father's footsteps, in 1913 Thor Hiorth Schøyen assumed the position of Norway's government entomologist. In the first years, mycology was also included in this position, but in 1919 a separate position was created for a government mycologist, filled by Ivar Jørstad. Schøyen worked in an office with no assistants, and he responded to hundreds of pest and fungal disease requests annually. He also made many business trips in Norway.

It grows best in well- ventilated locations with very good drainage; otherwise it is prone to fungal disease, in particular grey mould (Botrytis cinerea) of the branches and soil- borne Phytophthora and Pythium, and is often short-lived. It is propagated readily from cuttings of semi-hardened wood. Plants grown this way can be used to replace older plants when they die. Lechenaultia formosa can be grown in hanging baskets or rockeries.

Introduced animals and diseases had impacted the park area by the late 19th century. Galen Clark noted in the mid-1890s that native grasses and flowering plants in Yosemite Valley had been reduced in number by three-quarters. White pine blister rust, a fungal disease that infects conifer trees, was accidentally introduced in British Columbia in 1910 and had reached California by the 1920s. It has since infected many sugar pine trees in the Yosemite area.

However, since eggplants can be particularly susceptible to pests such as whiteflies, they are sometimes grown with slightly less susceptible plants, such as chili pepper, as a sacrificial trap crop. Four years should separate successive crops of eggplants to reduce pest pressure. Common North American pests include the potato beetles, flea beetles, aphids, whiteflies, and spider mites. Good sanitation and crop rotation practices are extremely important for controlling fungal disease, the most serious of which is Verticillium.

Sugarcane smut is a fungal disease of sugarcane caused by the fungus Sporisorium scitamineum. The disease is known as culmicolous, which describes the outgrowth of fungus of the stalk on the cane. It attacks several sugarcane species and has been reported to occur on a few other grass species as well, but not to a critical amount. The most recognizable characteristic of this disease is a black or gray growth that is referred to as a "smut whip".

Sporotrichosis is a disease caused by the infection of the fungus Sporothrix schenckii. This fungal disease usually affects the skin, although other rare forms can affect the lungs, joints, bones, and even the brain. Because roses can spread the disease, it is one of a few diseases referred to as rose-thorn or rose-gardeners' disease. The species was named for Benjamin Schenck, a medical student who in 1896 was the first to isolate it from a human specimen.

Removing debris in the spring will remove inoculum from the site. Disposal of berries during harvest that have signs and symptoms of gray mold will reduce inoculum for the following year. Biochar, a form of charcoal, can be applied as a soil amendment to strawberry plants to reduce the severity of the fungal disease by stimulating defense pathways within the plant. Gray mold can be chemically controlled with well-timed fungicide applications starting during the first bloom.

Because Cyclaneusma is an ascomycete it produces two spore types, an asexual (conidiomata) and sexual (ascomycota) spore. Controlling Cyclaneusma has presented a challenge as the disease can survive on both living and dead needles during the winter months. Effective management methods include planting new pines in non-shaded, well drainable soil as well as spraying fungicide. Cyclaneusma Needle Cast is an important fungal disease because it directly impacts the commercial value of decorative pines as well as lumber.

A decade later, there were 3,000 banana farms in the country, each averaging approximately 158 acres in size. As of 1960, bananas exported from Ecuador accounted for 25 percent of the world's production, out-producing all of the Central American countries. In the late 1950s, a fungal disease called Panama disease caused huge losses to the banana crop. During the 1960s agrarian reform caused fragmentation of land holdings and multinational companies closed down due to labour trouble.

In addition, ratios of stable carbon isotopes from bristlecone pine tree rings are sensitive to past variations in moisture availability. This information can be used to reconstruct precipitation changes in the past. The Rocky Mountain population is severely threatened by an introduced fungal disease known as white pine blister rust, and by mountain pine beetles. Climate change may also affect the species as temperatures increased over a 30-year period throughout the southern Rocky Mountain range.

Male S. latifolia tend to have a lower rate of infection compared to female S. latifolia because males have the ability to drop contaminated flowers before the entire plant is infected by M. violaceum; whereas, females do not have that male phenotype. So females hold onto the flowers with the intention to develop fruits carrying seeds with the purpose of creating offspring. However, these "offspring" merely carry the fungal disease and cannot develop into mature plants.

Puccinia thaliae is the causal agent of canna rust, a fungal disease of Canna. Symptoms include yellow to tan spots on the plant's leaves and stems. Initial disease symptoms will result in scattered sori (clustered sporangia), eventually covering the entirety of the leaf with coalescing pustulates. Both leaf surfaces, although more predominant on the underside (abaxial) of the leaf, will show yellow to brownish spore-producing these pustulate structures, and these are the signs of the disease.

Gummosis is a nonspecific condition of stone fruits (peach, nectarine, plum, and cherry) in which gum is exuded and deposited on the bark of trees. Gum is produced in response to any type of wound – insect, mechanical injury, or disease. Apiosporina morbosa is a major fungal disease in the Northern Americas, with many urban centres running back knot fungus management programs. This disease is best managed by physical removal of knot-bearing branches to prevent spore spread and immediate disposal of infected tissue.

Peach leaf curl is a distinctive and easily noticeable fungal disease, and the severity of the symptoms depends on how early infection has occurred. Diseased leaves can usually be identified soon after they emerge from the bud, due to their red color and twisted shape. As the leaves develop, they become increasingly distorted, and ultimately thick and rubbery compared to normal leaves. The color of the leaves changes from the normal green to red and purple, until a whitish bloom covers each leaf.

No species is recorded as having become extinct, despite over 50% of recent worldwide extinctions being Australian. Three species are listed as Threatened, two as Vulnerable and Geocrinia alba as Critically endangered. Threats to the species include the fungal disease Chytridiomycosis, though no infection has yet been recorded, and damage to habitat from altered land use and fire regimes. These processes have caused decline in many populations, however, some have successfully colonized newly created habitats such as dams or suburban gardens.

The fungicidal treatments would cause workers to inhale fungicidal dust and come into direct skin contact with the chemicals without means of decontamination until the end of their workday. These chemicals would be studied and proven to carry their own negative repercussions towards the laborers and land of these host nations. While the Panama disease was the first major challenging and aggressive epidemic, again United Fruit would be faced with an even more combative fungal disease, Black sigatoka, in 1935.

Chytridiomycosis caused by a chytrid fungus is a deadly fungal disease that has wiped out 30 amphibian species across the globe and has sent overall amphibian populations in decline. The fungus Batrachochytrium dendrobatidis can be found on every continent with fertile soil and has contributed to the loss of some species of frogs and salamanders. In fact, it is estimated that 287 species of amphibians are infected with this disease in over 35 countries.Kriger, Kerry M., and Jean-Marc Hero.

Those immigrants who arrived after 1759 were mainly Highland farmers who had been forced off their crofts (rented land) during the Highland and Lowland Clearances to make way for sheep grazing due to the British Agricultural Revolution. Others came as a result of famine. In 1846, potato crops were blighted by the same fungal disease responsible for the Great Irish Famine, and most Highland crofters were very dependent on potatoes as a source of food.

Ophidiomyces ophiodiicola is a keratinophilic fungus from the family Onygenaceae of the order Onygenales. O. ophiodiicola is an emerging pathogen of captive and wild snakes in North America and Europe. It is reported to cause ophidiomycosis (formerly known as snake fungal disease or SFD) in many different species of snakes; clinical signs include skin swelling, crusts, and nodules of the skin. The mode of transmission is unknown, but is speculated to occur with direct contact between snakes or with the contaminated environment.

While infection of Botrytis cinerea can be welcomed in some white grape varieties, in red wine grapes such as Gueuche noir it contributes to the viticultural hazard of botrytis bunch rot (pictured). Gueuche noir is a mid to late-ripening grape variety that can be very fertile and high yielding. The grape's thin skins and small, compact bunches are susceptible to a number of viticultural hazards including fungal disease like downy and powdery mildew as well as botrytis bunch rot.

Perhaps the most significant agricultural usage of V. riparia is as grafted rootstock for Vitis vinifera. Important advantages of the use of V. riparia (and hybrids between it and other Vitis species) include resistance to phylloxera and adaptation to variant soil types. Due to the extensive cold hardiness and fungal disease resistance of this species, it has been used extensively in grape breeding programs to transfer cold hardy and disease resistant genes to domesticated grapes. The French-American hybrid grapes are notable examples of these attempts.

Wild birds were brought to the Bahamas from Jamaica to repopulate avian life on New Providence Island. The Board of Agriculture requested early-maturing vegetables from Jamaica and Trinidad. Legislation was passed that standardized procedures for hoisting hurricane signal flags, issuing a set of flags to all lighthouses of the British Imperial Lighthouse Service. Along with a fungal disease that killed 99% of sponges in the Bahamas, the storm precipitated the demise of the sponging industry in the colony, leading to tourism becoming the islands' chief industry.

In Britain the Scottish Crop Research Institute was tasked with developing new varieties suitable for growing in the north of the country. They produced new cultivars that had greater cold tolerance, especially in the spring, ripened earlier and more evenly and had greater fungal disease resistance. Frost tolerance was improved by selecting for late flowering and genetic research identified genes involved in resistance to gall mite and the blackcurrant reversion virus. 'Ben Lomond' was the first of the 'Ben' varieties and was released in 1975.

Infection occurs when an insect comes in contact with the Entomophthora pathogen. Once the insect has been infected, the fungal disease begins its transmission and development throughout the body, causing harm and soon death to the host. The stages in which this pathogen undergoes to impact the host and cause harm, is referred to its life cycle. The first stage of the life cycle is infection, referring to the invasion of micro-organisms into a genome, these micro-organisms are foreign to the body.

Since Bishmizzine lies on the route of migratory birds some experts have postulated that the water holes became a rest area for migrating birds ex storks and hence the seeds were carried in their feathers from distant areas. The disease burden of fungal olive disease peacock eye remains high however and a concerted effort by farmers, government and NGOs is needed. A large area of Bishmizzine remains free of fungal disease and produces some of the best extra virgin olive oil and table olives in the area.

Dutch elm disease (DED) is a fungal disease that has ravaged the American elm, causing catastrophic die- offs in cities across the range. It has been estimated that only approximately 1 in 100,000 American elm trees is DED-tolerant, most known survivors simply having escaped exposure to the disease. However, in some areas still not infested by DED, the American elm continues to thrive, notably in Florida, Alberta and British Columbia. There is a notable grove of old-growth American elm trees in Manhattan's Central Park.

In January 2019, an expedition to a Bolivian cloud forest led to the discovery of five more individuals: three males and two females. The re-discovered frogs will be treated against chytridiomycosis, a fungal disease causing widespread decline of amphibians. After treatment, Romeo will be introduced to a female called Juliet. Despite this, there are concerns that there are too few frogs left in the wild for a sustainable long-term population, and thus captive breeding is considered the best way to restore the species.

Botrytis cinerea or grey mold is a fungal disease that infects most ornamental plants. The fungus causes a decay of plant tissues and will grow fuzzy gray-brown mold over the decaying areas, such as the buds, leaves, and flowers. Parts of the plant may shrivel and die after exposure to the mold, particularly the flowers. Typically the fungus will only infect plants through an open wound or when the plant is under stress, but it has also been known to infect plants in humid conditions.

The Green Flea Markets are held every Saturday morning in Davies Park, West End, Queensland (Australia). The Market site is home to a number of giant fig trees which have recently become infected with a fungal disease (Phellinus noxius) that is spreading all over Queensland. This is particularly interesting as the treatment of the trees is threatening the existence of this unique market. The Green Flea Markets have been run for over six years by creator Peter Hackworth, whose licence expired in early 2009.

The caterpillars of this species defoliate the trees, and are hazardous to human health; their bodies are covered with poisonous hairs which can cause rashes and respiratory problems. In California, oaks are affected by the fungal disease foamy bark canker. The eastern grey squirrel (Sciurus carolinensis) is an invasive species across North America and Europe where they are known to strip bark off of a variety of large trees, including oaks. Bark stripping can result in the death of the leading shoot and decreased crown size.

Hymenoscyphus fraxineus is an Ascomycete fungus that causes ash dieback, a chronic fungal disease of ash trees in Europe characterised by leaf loss and crown dieback in infected trees. The fungus was first scientifically described in 2006 under the name Chalara fraxinea. Four years later it was discovered that Chalara fraxinea is the asexual (anamorphic) stage of a fungus that was subsequently named Hymenoscyphus pseudoalbidus and then renamed as Hymenoscyphus fraxineus. Trees reported dying in Poland in 1992 are now believed to have been infected with this pathogen.

Intelligent and proficient in several languages, Hermann Jaeger worked to breed over 100 new varieties of grapes, many of which came from wild Ozarks grapes - grapes commonly called "possum grapes". He also became the first grower in the Western world to spray vines to control fungal disease. He readily communicated with other grape experts around the world, sharing information about his work and learning from the works of others. He also wrote articles for scientific and grape journals, explaining the mysteries of grapes and his work on his farm.

Symptom on wheat caused by F. graminearum (right:inoculated, left:non- inoculated) Fusarium ear blight (FEB) (also called Fusarium head blight, FHB, or scab), is a fungal disease of cereals, including wheat, barley, oats, rye and triticale. FEB is caused by a range of Fusarium fungi, which infects the heads of the crop, reducing grain yield. The disease is often associated with contamination by mycotoxins produced by the fungi already when the crop is growing in the field. The disease can cause severe economic losses as contaminated grain cannot be sold for food or feed.

It differs in having slightly larger cones, and needles with three resin canals instead of two as in the Swiss pine. Like other European and Asian white pines, Swiss pine is very resistant to white pine blister rust (Cronartium ribicola). This fungal disease was accidentally introduced from Europe into North America, where it has caused severe mortality in the American native white pines in many areas, notably, Western white pine and the closely related whitebark pine. Swiss pine is of great value for research into hybridisation to develop rust resistance in these species.

Siberian pine is treated as a variety or subspecies of the very similar Swiss pine (Pinus cembra) by some botanists. It differs in having slightly larger cones, and needles with three resin canals instead of two in Swiss pine. Like other European and Asian white pines, Siberian pine is very resistant to white pine blister rust (Cronartium ribicola). This fungal disease was accidentally introduced from Europe into North America, where it has caused severe mortality in the American native white pines in many areas, notably the closely related whitebark pine.

It can grow in a wide variety of climates, being able to withstand temperatures as low as , while tolerant of humid subtropical climates such as in Brisbane. Once established, it will tolerate extended dry periods. In wet or humid situations, the foliage underneath may turn brown, a situation that may be overcome by using a stone or pebble mulch underneath. In 2003, it was reported that the fungal disease Phytophthora palmivora had been detected in plant nurseries in Sicily, leading to root rot and death of potted Grevillea cultivars.

Because these models are necessarily simplifying natural conditions (often based on the assumption that weeds, disease and insect pests are controlled), it is not clear whether the results they give will have an in-field reality. However, some results are partly validated with an increasing number of experimental results. Other models, such as insect and disease development models based on climate projections are also used (for example simulation of aphid reproduction or septoria (cereal fungal disease) development). Scenarios are used in order to estimate climate changes effects on crop development and yield.

Alyogyne 'Ruth Bancroft' hybrid, grown by and named after Ruth Bancroft In the late 19th century, Bancroft's husband's grandfather, Hubert Howe Bancroft, had started a 400-acre fruit farm, which produced walnuts and Bartlett pears. The farm operated until the late 1960s, when the land was rezoned for residential use and sold to developers. The trees, sick with a fungal disease called blackline, were cut down, and the soil was dry and bare. In 1971, Ruth Bancroft's husband, inherited three acres of empty land, which he gifted to his wife to expand her garden.

Renowned for its vivid blue flowers, it was first grown in the United Kingdom in the 1840s. Many cultivars were sold in the 1960s that are no longer available. It grows best in well-ventilated locations with very good drainage, otherwise it is prone to fungal disease, in particular grey mould (Botrytis cinerea) of the branches and soil-borne Phytophthora and Pythium, and is often short-lived, lasting four to six years in a good location, or perishing within a year in a poor one. It is readily propagated by cuttings.

The total area of occupancy of the Chamula mountain brook frog is less than and it is only known from five locations. The montane cloud forests where it lives are under threat from human activities, and although this is quite a common species where it is found, populations of these frogs are thought to be declining. Another possible threat is the fungal disease of amphibians, chytridiomycosis. For these reasons, the International Union for Conservation of Nature (IUCN) has assessed the conservation status of this frog as being "endangered".

The trees flower fairly early (in March in western Europe) and the blossom is damaged or killed if temperatures drop below about . However, if the flowers are not fully open, they can tolerate a few degrees colder. Climates with significant winter rainfall at temperatures below are also unsuitable for peach cultivation as the rain promotes peach leaf curl, which is the most serious fungal disease for peaches. In practice, fungicides are extensively used for peach cultivation in such climates, with >1% of European peaches exceeding legal pesticide limits in 2013.

Coniothyrium hellebori is a fungus that causes the most common fungal disease for helleborus species known as Hellebore black spot or leaf spot. The disease is most common not only in botanical and ornamental gardens, but also in hellebore nurseries as well. Visible symptoms include blackish-brown spots that often appear as rings on the leaf blade or at the margins of the leaf. The spots will continue to grow larger as the disease progresses, retaining an elliptical or circular shape and turning a dark brown or black color.

Berberis species are used as food plants by the larvae of some Lepidoptera species, including the moths barberry carpet moth (Pareulype berberata), and mottled pug (Eupithecia exiguata). Berberis species can infect wheat with stem rust, a serious fungal disease of wheat and related grains. Berberis vulgaris (European barberry) and Berberis canadensis (American barberry) serve as alternate host species of the rust fungus responsible, the wheat rust fungus (Puccinia graminis). For this reason, cultivation of B. vulgaris is prohibited in many areas, and imports to the United States are forbidden.

She took her thesis to the Swiss Federal Institute for Agroecology in Zürich, Switzerland. She taught two courses as a professor’s assistant and began her work on the wheat genome. At the Swiss Federal Institute for Agroecology she worked in a laboratory under the supervision of Dr. B. Keller to work on structural and evolutionary genomics in wheat and barley. She joined the Institute of Plant Biology at the University of Zurich as a junior group leader and continued her grain research investigating the genes responsible for fungal disease resistance.

A photomicrograph of Candida albicans showing hyphal outgrowth and other morphological characteristics Some species of yeast are opportunistic pathogens that can cause infection in people with compromised immune systems. Cryptococcus neoformans and Cryptococcus gattii are significant pathogens of immunocompromised people. They are the species primarily responsible for cryptococcosis, a fungal disease that occurs in about one million HIV/AIDS patients, causing over 600,000 deaths annually. The cells of these yeast are surrounded by a rigid polysaccharide capsule, which helps to prevent them from being recognised and engulfed by white blood cells in the human body.

While an overarching reason behind this destruction remains unknown, overgrazing by cattle, camels, and goats is believed to have been a significant contributor, along with rain, climate change, and a fungal disease. Hunting, the gathering of firewood, egg collecting, and general human disturbance are also believed to be threats. At the Mabla Mountains site, the habitat is also being degraded by the collection of firewood and overgrazing. In 1937, part of the Forêt du Day site was set aside as Day Forest National Park; this designation is no longer valid.

Brown spot of rice is a plant fungal disease that usually occurs on the host leaves and glume, as well as seedlings, sheaths, stems and grains of adult host plants. Hosts include Oryza (Asian rice), Leersia (Cutgrass), Zizania (Wild rice), and other species as well such as Echinochloa colona (junglerice) and Zea mays (maize). Cochliobolus miyabeanus may cause a wide range of symptoms. General symptoms occurring on the hosts can be observed on many parts of the plant, including leaves, seeds, stems and inflorescences, along with the presence of brown spot.

It has been proposed to genetically modify some plant species threatened by extinction to be resistant invasive plants and diseases, such as the emerald ash borer in North American and the fungal disease, Ceratocystis platani, in European plane trees. The papaya ringspot virus (PRSV) devastated papaya trees in Hawaii in the twentieth century until transgenic papaya plants were given pathogen- derived resistance. However, genetic modification for conservation in plants remains mainly speculative. A unique concern is that a transgenic species may no longer bear enough resemblance to the original species to truly claim that the original species is being conserved.

It was originally extracted from Streptomyces nodosus, a filamentous bacterium, in 1955, at the Squibb Institute for Medical Research from cultures of an undescribed streptomycete isolated from the soil collected in the Orinoco River region of Venezuela. Two antifungal substances were isolated from the soil culture, Amphotericin A and Amphotericin B, but B had better antifungal activity. For decades it remained the only effective therapy for invasive fungal disease until the development of the azole antifungals in the early 1980s. Its complete stereo structure was determined in 1970 by an X-ray structure of the N-iodoacetyl derivative.

The Panamanian golden frog is endemic to Panama, living close to mountain streams on the eastern side of the Tabasará mountain range in the Coclé and Panamá provinces. Its geographic range previously extended as far east as the town of El Copé in western Coclé Province before the onset of the fungal disease chytridiomycosis, which caused the El Copé population to rapidly collapse in 2004. Vital habitat is lost each year to small farms, commercialized agriculture, woodlot operations, livestock range, industrial expansion, and real estate development. Individuals are kept in captive- breeding programmes in more than 50 institutions across North America and Panama.
|
|
No current remedies prevent or control the disease in the wild, but efforts are being made. One attempt was made to protect a wide variety of frogs from the disease by using the bacterium Janthinobacterium lividium that produces a chemical against the infections; however, the skin of Panamanian golden frogs was unsuitable for the bacterium used. The San Diego Zoo started a conservation effort and received their first frogs in 2003. Since then, they have been able to successfully breed 500 individuals in captivity but will not release them into the wild until the fungal disease is less of a threat.

It inhabits dry gulches and ridges in coastal mesic and mixed mesic forests on the Koolau and Waianae Ranges. Associated plant species include maile (Alyxia oliviformis), ahakea lau nui (Bobea elatior), Carex meyenii, uluhe (Dicranopteris linearis), kōlea lau nui (Myrsine lessertiana), olopua (Nestegis sandwicensis), hala pepe (Pleomele halapepe), ālaa (Pouteria sandwicensis), alahee (Psydrax odorata), hao (Rauvolfia sandwicensis), and pūkiawe (Styphelia tameiameiae). It is threatened by habitat loss and recently Puccinia psidii, a non-native fungal disease. In 2008 there were fewer than 300 mature plants in the Koolau Range and only three in the Waianae Range.

Raboso was in the past the most cultivated grape variety of eastern Veneto; Venetian navigators called it vin de viajo, "wine of travel", because it was the most resistant to aging and transport. Its popularity decreased in the 20th century, and today the vineyards of Raboxo are just 1–2% of the total amount of vineyards in Veneto. The vine ripens relatively quite late, producing good yields with high resistance to fungal disease and rot.J. Robinson Vines, Grapes & Wines pg 210 Mitchell Beazley 1986 The grape crossed with another Veneto wine grape, Marzemina bianca, to produce Raboso Veronese.

Although the full reasons for the decline are uncertain, it can be at least partly attributed to the fatal amphibian fungal disease chytridiomycosis.Egerton, p. 385. Another theory for the decline might be, as research shows, that species from the Southern Hemisphere are on average 4.6 million years old, compared to an average 2.9 million years old for the Northern Hemisphere: Researchers believe this age difference is because of the history of severe ice ages in the Northern Hemisphere, which may drive older species to extinction. The saltwater crocodile is the largest species of crocodile in the world.

Removing it is time-consuming as the herbicide used to control it has to be injected straight into the root system, to prevent it reaching other flora. Alder trees are also at risk at the reserve, this time from a fungal disease caused by Phytophthora alni. Being water-borne, this infection could spread to all the alders on the site. Another natural threat is that of the introduced Harlequin ladybird which was first identified at the site in June 2008 and is a severe threat to the native seven-spot ladybird population as it is such an effective aphid predator.

The last record of this species was from 1990, and it has not been seen since (as of August 2007), despite it having been searched for. It has not been seen in Cascajal, San Jose Province, since 1972. Because it has seemingly disappeared from the areas in which it has almost only been collected - otherwise pristine, well-managed nature reserves, infection by the introduced fungal disease chytridiomycosis has been suggested as the reason of decline, as this has also impacted other similar frogs from similar habitats. The IUCN also mentions unspecified possible impacts from climate change.

Up until the advent of modern therapies, favus was widespread worldwide; prior to Schönlein's recognition of it as a fungal disease, it was frequently confused with Hansen's disease, better known as leprosy, and European sufferers were sometimes committed to leprosaria. Today, due to this species' high susceptibility to the antifungal drug griseofulvin, it has been eliminated from most parts of the world except rural central Asia and scattered rural areas of Africa. It is mainly a disease connected to demographic poverty and isolation, but is so readily treatable that it is among the diseases most likely to be completely eliminated by modern medicine.

After enrolling at RMIT in 1987, Wade completed her degree program three years later and earned a Bachelor of Applied Science in Applied Biology in 1990. After realizing that it was going to be difficult to find an occupation with her three-year degree, Wade stayed at RMIT for an Honours year and did a research project on fungal disease of grevilleas. In 1992, Wade was awarded the Australian Postgraduate Research Award which allowed her to pursue a PhD at RMIT. It was during her PhD studies that Wade began research on the weed thornapple, which is some of her best-known work.

Chemical means of controlling Botryotinia polyblastis involve the use of fungicides. There are many varieties of fungicides available to prevent Botryotinia polyblastis infections and they should be applied twice throughout the season, once in late March and once in late April. Dicarboximide, chlorothalonil, fludioxonil, cyprodinil, pyraclostrobin and mancozeb are all common fungicides used to treat Narcissus fire, however formulations containing dicarboximide have been shown to be most effective. It is also possible to remove all the flowers from the fields before apothecial production and avoid having to deal with prevention or treatment of a fungal disease such as Botryotinia polyblastis.

The plant has been widely cultivated for hedges in New Zealand. Berberis vulgaris (European barberry) is the alternate host species of the wheat rust fungus (Puccinia graminis), a grass-infecting rust fungus that is a serious fungal disease of wheat and related grains. For this reason, cultivation of B. vulgaris is prohibited in Canada and some areas of the United States (Connecticut, Massachusetts, Michigan, New Hampshire). Salishan people have used "barberry" to treat acne in their traditional medicine, although bark of the native M. aquifolium (formerly B. aquifolium, Oregon grape) and other Mahonia species was used.

Many stands of Pinus albicaulis across the species' entire natural range are infected with white pine blister rust (Cronartium ribicola), a fungal disease introduced from Europe. In the northern Rocky Mountains of the United States, whitebark pine mortality in some areas exceeds 90 percent, where the disease infests nearly . Cronartium ribicola occurs in whitebark pine to the northern limits of the species in the coastal ranges of British Columbia and the Canadian Rocky Mountains. The blister rust has also devastated the commercially valuable western white pine in these areas and made serious inroads in limber pine (Pinus flexilis) populations as well.

Schwartz et al. stated that recovery is possible, but this will require a greater level of commitment and a dedicated increase in funding. Small experiments by Schwartz and Hermann in the 1990s found that planting cuttings in the native habitat is possible. Schwartz et al. recommended population augmentation by planting volunteers isolated by more than 100m from extant stands to reduce chance of contamination. The tree is well-represented in cultivation, and is widely planted for conservation purposes outside of its native range. Plants outside of its historic native distribution are undamaged by fungal disease and produce viable seed.

Southern corn leaf blight (SCLB) is a fungal disease of maize caused by the plant pathogen Bipolaris maydis (also known as Cochliobolus heterostrophus in its teleomorph state). The fungus is an Ascomycete and can use conidia or ascospores to infect. There are three races of B. maydis: Race O, Race C, and Race T; SCLB symptoms vary depending on the infectious pathogen's race. Race T is infectious to corn plants with the Texas male sterile cytoplasm (cms-T cytoplasm maize) and this vulnerability was the cause of the United States SCLB epidemic of 1969-19701 Ullstrup, A. J., Annual Review of Phytopathology 10 (1), 37 (1972).

In North America, hemlocks are also attacked by hemlock looper.USDA Forest Service NA-PR-05-92 Larger infected hemlocks have large, relatively high root systems that can bring other trees down if one falls. The foliage of young trees is often browsed by deer, and the seeds are eaten by finches and small rodents. Old trees are commonly attacked by various fungal disease and decay species, notably Heterobasidion annosum and Armillaria species, which rot the heartwood and eventually leave the tree liable to windthrow, and Rhizina undulata, which may kill groups of trees following minor grass fires that activate growth of the Rhizina spores.

Sen claimed the famine was caused by inflation, with those benefiting from inflation eating more and leaving less for the rest of the population. These studies, however, did not account for possible inaccuracies in estimates or the impact of fungal disease on the rice. De Waal states that the British government did not enforce the Famine Codes during the Bengal famine of 1943 because they failed to detect a food shortage. The Bengal famine of 1943 was the last catastrophic famine in India, and it holds a special place in the historiography of famine due to Sen's classic work of 1981 titled Poverty and Famines: An Essay on Entitlement and Deprivation.

Inoculation of virulent strains of Ophiostoma in elm cambium, Dorschkamp Institute for Forestry and Landscape planning, Wageningen 1984 (photograph: Mihailo Grbić) Many attempts to breed disease resistant cultivar hybrids have usually involved a genetic contribution from Asian elm species which have demonstrable resistance to this fungal disease. Much of the early work was undertaken in the Netherlands. The Dutch research programme began in 1928, and ended after 64 years in 1992, during which time well over 1000 cultivars were raised and evaluated. Still in use are cultivars such as 'Groeneveld', 'Lobel', 'Dodoens', 'Clusius' and 'Plantijn' although the resistance levels in these trees aren't high enough for good protection.

Phomopsis blight of juniper commonly infects the eastern red cedar, savin (Juniperus sabina), creeping juniper, and rocky mountain juniper plants (Juniperus scopulorum), but also has the ability to infect Chinese juniper and common juniper to varying degrees.UofI: Phomopsis Blight Although spores from diseased juniper plants infect healthy hosts in the fall, symptoms are usually not seen until late winter or early spring. Often the first symptom noted is the browning of needle tips as the disease invades young, vulnerable tissue. New shoots that are normally yellow-green in color begin to turn to red brown and then ashen gray as they slowly die from the fungal disease.

However, while the importing of this new North American plant material helped to stave off the phylloxera epidemic, it brought with it yet more problems-the fungal disease of downy mildew that first surfaced in 1878 and black rot that followed in the 1880s. The devastation to French vineyards brought with it the opportunity to explore new plantings and many vignerons began to experiment with hybrid plantings—starting first with the American hybrids (such as Delaware and Clinton) with genes from the more resistant American vines species and then moving on to French hybrids (such as Chambourcin and Vidal blanc) that produces wines with flavors more similar to European Vitis vinifera.

A revised version, which still includes her as one of the topics, was presented to the Dutch government on 3 October 2007. In June 2007, "Buddy" Elias donated some 25,000 family documents to the Anne Frank House. Among the artefacts are Frank family photographs taken in Germany and the Netherlands and the letter Otto Frank sent his mother in 1945, informing her that his wife and daughters had perished in Nazi concentration camps. In November 2007, the Anne Frank tree—by then infected with a fungal disease affecting the tree trunk—was scheduled to be cut down to prevent it from falling on the surrounding buildings.

Rue Foch with its typical 19th-century architecture During the 19th century the city thrived on the wine culture that it was able to produce due to the abundance of sun throughout the year. The wine consumption in France allowed Montpellier's citizens to become very wealthy until in the 1890s a fungal disease had spread amongst the vineyards and the people were no longer able to grow the grapes needed for wine. After this the city had grown because it welcomed immigrants from Algeria and other parts of northern Africa after Algeria's independence from France. In the 21st century Montpellier is between France's number 7th and 8th largest city.

Ghabrial was born in Cairo, where he attended public schools and then the College of Agriculture at Cairo University, gaining a BS in agriculture (1959). He worked at the Egyptian Ministry of Land Reform (1959–61) and then briefly did national service in the Egyptian Army. In 1961, he went to the United States on a government scholarship, and studied in the Plant Pathology Department of Louisiana State University, where he gained an MS (1963) and PhD (1965) in plant pathology, supervised by Thomas Pirone. His MS research was on tomato leaf mold, a fungal disease of tomatoes caused by Cladosporium fulvum (Passalora fulva).

Until the 1950s, the Gros Michel cultivar of banana represented almost all bananas consumed in the United States because of their taste, small seeds, and efficiency to produce. Their small seeds, while more appealing than the large ones in other Asian cultivars, were not suitable for planting. This meant that all new banana plants had to be grown from the cut suckers of another plant. As a result of this asexual form of planting, all bananas grown had identical genetic makeups which gave them no traits for resistance to Fusarium wilt, a fungal disease that spread quickly throughout the Caribbean where they were being grown.

Hypoxylon canker of shade trees is an ascomycete fungal disease (1,6). The fungal pathogen must take advantage of wounds in the host tree or unhealthy tree tissue to infect and colonize the host, as normal, robust trees are not very susceptible to infection (1). However, many hosts of Hypoxylon canker, such as red and post oaks, are especially sensitive to external factors; thus, they are easily stressed and can become susceptible hosts (2). It is often noted that Hypoxylon canker does not kill a tree--it merely capitalizes on trees that are already dying due to stress or other means, and may be a significant contributing factor to tree death (3).

It eats a diverse array of insects, foraging with a slow, erratic flight and navigating via echolocation. Though once considered one of the most common bat species in its range, its populations have declined rapidly since 2006 with the introduction of the fungal disease white-nose syndrome. It was listed as an endangered species in 2012 in Canada, and has been petitioned for inclusion on the US endangered species list. Along with the silver-haired bat, the tricolored bat is one of two bat species whose rabies variants have most frequently been implicated in human rabies deaths in the US, with sixteen deaths from 1958-2000\.

Oocysts (spores) of an Eimeria species (Eimeria heidti ) have been recovered from its guano (feces). The tricolored bat has experienced severe population decline as a result of the fungal disease white-nose syndrome, which arrived in the US in 2006, with losses of 70% and greater detected in multiple US states. The disease kills bats by colonizing their skin during the winter, causing them to arouse from torpor and burn through their limited fat reserves. Though its population experienced dramatic reduction, subsequent studies have found that their numbers may be stabilizing, though hibernacula where many individuals once roosted may only host fewer than five bats, or even one solitarily.

Variegation produced by the tulip breaking virus Botrytis tulipae is a major fungal disease affecting tulips, causing cell death and eventually the rotting of the plant. Other pathogens include anthracnose, bacterial soft rot, blight caused by Sclerotium rolfsii, bulb nematodes, other rots including blue molds, black molds and mushy rot. The fungus Trichoderma viride can infect tulips, producing dried leaf tips and reduced growth, although symptoms are usually mild and only present on bulbs growing in glasshouses. Variegated tulips admired during the Dutch tulipomania gained their delicately feathered patterns from an infection with the tulip breaking virus, a mosaic virus that was carried by the green peach aphid, Myzus persicae.

While Prescott was doing his canning research, he also taught biology at MIT. This included courses in bacteriology, general biology, botany, genetics. He also rose through the ranks at MIT, moving to assistant professor in 1903 and associate professor in 1909 and even traveled through Europe during 1900, mainly Belgium, Germany, Denmark, Switzerland, and France, to assist in research per Sedgwick's request. Prescott published papers on water bacteriology, milk bacteriology, and public health bacteriology from 1895 to 1910.Goldblith. pp. 17-20, 33-43. His research would continue from 1910 to 1921 into banana fungal disease in Costa Rica in 1917 and 1918 that would lead to a disease-resistant banana.Goldblith. pp.53-4.

Karnal bunt (also known as partial bunt) is a fungal disease of wheat, durum wheat, and triticale. The smut fungus Tilletia indica, a basidiomycete, invades the kernels and obtains nutrients from the endosperm, leaving behind waste products with a disagreeable odor that makes bunted kernels too unpalatable for use in flour or pasta. While Karnal bunt generally does not lead to devastating crop losses, it has the potential to dramatically decrease yield and poses additional economic concerns through quarantines which limit the export of suspected infectious wheat products from certain areas, including the U.S. Several chemical control methods exist for Karnal bunt of wheat, but much work remains to be done in identifying resistant host varieties.

Characteristic shape in old field succession Eastern juniper is a pioneer species, which means that it is one of the first trees to repopulate cleared, eroded, or otherwise damaged land. It is unusually long lived among pioneer species, with the potential to live over 900 years. It is commonly found in prairies or oak barrens, old pastures, or limestone hills, often along highways and near recent construction sites. It is an alternate host for cedar–apple rust, an economically significant fungal disease of apples, and some management strategies recommend the removal of J. virginiana near apple orchardsWest Virginia University: Cedar-Apple Rust, Gymnosporangium juniperi- virginianae In many areas it is considered an invasive species, even if native.

The cause of the fungal disease was not known at the time and the weather was thought to be to blame. Although the commission was powerless to solve the problem, their report brought about the repeal of the 1815 Corn Laws which had forbidden the import of cheap wheat from America. This helped to alleviate the effects of the disease on populations that had become reliant on the monoculture of potatoes.Stearn, 54–55 He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1859. Lindley was very industrious and hardworking and published a number of works including ‘’The Genera and Species of Orchidaceous Plants’’, the writing of which occupied him for ten years.

Rhizoctonia solani causes the post-emergence disease wirestem, resulting in killed seedlings ("damping-off"), root rot or stunted growth and smaller heads. Cabbage moth damage to a savoy cabbage One of the most common bacterial diseases to affect cabbage is black rot, caused by Xanthomonas campestris, which causes chlorotic and necrotic lesions that start at the leaf margins, and wilting of plants. Clubroot, caused by the soilborne slime mold-like organism Plasmodiophora brassicae, results in swollen, club-like roots. Downy mildew, a parasitic disease caused by the oomycete Peronospora parasitica, produces pale leaves with white, brownish or olive mildew on the lower leaf surfaces; this is often confused with the fungal disease powdery mildew.

All parties involved in la argolla, from the government officials to the bankers and the growers, were professed militants of the Liberal cause. It was not only the political fortunes of the party that fell victim to their financial activities, however, but also the national economy, which experienced runaway inflation as a result of the printing of money by the private banks. The severe economic problems during the final years of Liberal rule were also partially caused by factors beyond the control of the politicians. A fungal disease that ravaged Ecuador's cacao trees and the growth of competition from British colonies in Africa abruptly ended conditions that had favored Ecuador's exportation of cacao for over a century.

In the 1850s, the fungal disease powdery mildew began to ravage vineyards in nearby Galicia, opening up the market up for Rioja bodegas, which had been only slightly affected. The completion of a railway system linking Logroño to Bilbao, Madrid and Irun coincided with the onset of the phylloxera epidemic in Europe. The French were the first and hardest hit by the louse, which created an immediate and insatiable demand for all the wine the Rioja could produce. Amidst devastation in the French wine industry, dozens of négociant and French winemakers, mostly from Bordeaux, traveled to the Rioja to set up wineries, where they could continue to produce wine – bringing with them extensive knowledge, techniques and experience.

In order to position itself correctly, it has short, stumpy legs, as well as long, sharp claws and very stiff tail feathers. The woodpecker will more than likely choose for its nest a tree with a fungal disease, such as heart rot, although some will utilise a living, healthy tree. Once a hole has been made, the black woodpecker chips downwards through the trunk of the tree, creating a nesting chamber, the only lining being the woodchips created throughout the process. The black woodpecker's excavations provide homes for many other species of bird and mammal, and is therefore considered to be a "keystone" species in many of its habitats throughout its range.

The threatened hellbender A general decline in living amphibian species has been linked with the fungal disease chytridiomycosis. A higher proportion of salamander species than of frogs or caecilians are in one of the at-risk categories established by the IUCN. Salamanders showed a significant diminution in numbers in the last few decades of the 20th century, although no direct link between the fungus and the population decline has yet been found. The IUCN made further efforts in 2005 as they established the Amphibian Conservation Action Plan (ACAP), which was subsequently followed by Amphibian Ark (AArk), Amphibian Specialist Group (ASG), and finally the umbrella organization known as the Amphibian Survival Alliance (ASA).

His students included Guillermo Seeber, who described the parasite Rhinosporidium seeberi, and Alejandro Posadas, who with Wernicke first described the fungal disease Coccidioidomycosis. Wernicke was a founding member and served two terms as President of the Asociación Médica Argentina (Argentine Medical Association) from 1894-1895 and from 1896-1897. He was vice-president of the First Latin American Scientific Congress held in Buenos Aires on April 11, 1898, where he led the medical sciences section. At the Second Latin American Scientific Congress, held in Montevideo from March 20 to 31, 1901, he served as president of the board as well as being president of the coordinating committee in Argentina and the official delegate of the Argentine government.

Leptodactylus fallax, commonly (and deceptively) known as the mountain chicken or giant ditch frog, is a critically endangered species of frog that is native to the Caribbean islands of Dominica and Montserrat. The population declined by at least 80% from 1995 to 2004, with further significant declines later. A tiny wild population remains on Dominica where there are efforts to preserve it, but few or none survive in the wild on Montserrat and its survival now relies on a captive breeding project involving several zoos. The initial decline was linked to hunting for human consumption, along with habitat loss and natural disasters, but the most serious threat now appears to be the fungal disease chytridiomycosis, which was the primary cause of the most recent rapid decline.

Perhaps the greatest, and least understood, threat to the mountain chicken frog today is the deadly fungal disease chytridiomycosis. This disease, which has wiped out many amphibian populations across the globe, established on Dominica in 2002, and in just 1½ year the population on the island declined to near-extinction. Although there have been indications that the Dominican population possibly is slowly starting to recover from this rapid decline, by 2017 it was still estimated to number less than 200 individuals and this was before Hurricane Maria, which might have negatively impacted the tiny population. Sometime between 2005 and 2009 the fungus was introduced to Montserrat, perhaps via small frogs on imported banana leaves, and it spread southwards from northern ports along river systems.

Many vineyards operate without the need for any chemical spraying, a condition conducive to organic viticulture. The periodic occurrence of the El Niño phenomenon can have a sharp influence on climate condition during a growing season-such as the case during the 1998 vintage when prolong heavy rains brought by El Niño led to widespread rot and fungal disease. The Andes Mountains are the dominant geographical feature of Argentine wine regions, with the snow-capped mountains often serving as a backdrop view to the vineyards. As the winter snows start to melt in the spring, an intricate irrigation system of dams, canals and channels brings vital water supplies down to the wine regions to sustain viticulture in the dry, arid climates.

The policy encouraged the expansion of rubber farms in the north and northeast and is partly to blame for an oversupply of rubber as it was implemented with few restrictions. The program caused rubber farms in Isan to expand by 17 percent per year, with little understanding of rubber's global supply and demand issues. In 2019, south Thailand rubber growers were hit by the fungal disease Pestalotiopsis. More than 330,000 rai of rubber trees in Narathiwat, Yala, Pattani, and Trang Provinces have been damaged by Pestalotiopsis leaf fall disease since it was detected in September 2019. The disease makes the rubber tree leaves fall and production drops up to 50 percent. Rubber output has dropped by 40,000 tonnes as of November.

L. pakeka on Maud Island L. pakeka is classed as nationally endangered in the New Zealand Threat Classification System. The entire species was initially confined to a 16-ha forest remnant on 309-ha Maud Island. Although its population on Maud Island is estimated to be 27,500–39,500, conservation has focused on establishing new populations on different islands, because the species is still vulnerable to fungal disease, natural disaster, climate change, or the arrival of mammalian predators. Maud Island suffered an incursion of mice in 2013, but these were eradicated and the island was declared predator-free in November 2016. In 1984–85 100 frogs were transferred by the Department of Conservation to a different part of Maud Island, successfully starting a new colony.

The big brown bat is not considered at risk for extinction, and is evaluated as the lowest conservation priority by the International Union for Conservation of Nature (IUCN). While some other bat species in its range have experienced dramatic population declines due to the fungal disease white-nose syndrome, the big brown bat is relatively resistant to the effects of the disease, and some populations have even increased since the syndrome arrived in North America. Like all bats in the US, the big brown bat can be impacted by rabies, though some individuals have immunity against the virus. Even though sick bats are more likely to be submitted for testing, in 2011, only 3.8% of submitted big brown bats were positive for the rabies virus.

Blackleg is a fungal disease of canola that results in major yield loss in affected crops. It overwinters on infected stubble (leftover crop residue) that is left on farm fields, and can continue to produce spores, infecting future crops, until the stubble is buried or broken down completely. The observation that C. olla grows and fruits on canola stubble has led to research on the potential of this fungus to degrade canola stubble, and reduce the incidence of stubble-borne diseases like blackleg and blackspot. In a study of its lignin-degrading abilities, C. olla was shown to colonize canola, wheat, and barley residue, but appeared to have a preference for the woody taproots of canola as compared to the cereal residue.

When his father needed to do business in St. Louis, Gerdemann used to be dropped off at the Missouri Botanical Garden, developing, then, his will to achieve something different as a career. Gerdemann completed his undergraduate and Master's degree in botany at the University of Missouri. To make his way through college he lived a simple life and had several jobs to pay his studies. He worked as a waiter at a women's college; had the responsibility of counting seeds and correct mistakes in the inventory records at the University's herbarium, where he was recognized for his knowledge about plants; and during summers he had a job at the Oregon Bureau of Land Management and the Forest Service, working inside Oregon's forests with the management of a fungal disease that affects white pine, the white pine blister rust (Cronartium ribicola).

The tree in 2003 Concerns about the tree's health date back to at least 1993, when a soil analysis revealed that leakage from a nearby underground domestic fuel tank was endangering the tree's root system. The city of Amsterdam spent €160,000 on a soil sanitation program to save the tree. For the last several years, the tree was attacked by a particularly aggressive fungus (Ganoderma applanatum, also called "Artist's Conk" or "Artist's Bracket") which rotted the wood and undermined the tree's stability. Additionally, horse-chestnut leaf miner moth caterpillars (Cameraria ohridella) ate the tree's leaves, causing them to turn brown prematurely and fall off. On 26 May 2005, the tree's crown was drastically trimmed after a six-month study by botanists concluded that this was the best way to ensure the tree's stability. However, the fungal disease continued to thrive, and a 2006 study estimated that 42% of the wood was rotten.

The disease is spread by airborne fungal spores and was first discovered in Northwest Christmas tree farms in 1983.Schmitz, John. Fungal disease of true firs attacking Christmas trees , The Capital Press, June 28, 2002, via Washington State University. Retrieved September 3, 2007. The plant pathogen, Phytophthora ramorum, which causes "sudden oak death" (SOD), is a fungus-like protist which was identified in the early 1990s. By 2002, sudden oak death had been reported along the California coast and the Oregon Coast, and two species of conifer were identified as hosts of the pathogen, Douglas fir and coast redwood. Between 2003 and 2005 P. ramorum was detected in Douglas fir, grand fir, white fir and California red fir on Christmas trees in Santa Clara County.A Christmas Tree Grower's Guide to Sudden Oak Death (Phytophthora ramorum), (PDF file), College of Natural Resources, University of California, Berkeley, November 20, 2006.
