Cercospora minima is a fungal plant pathogen. In the European pear, it is the cause of the disease known as late leaf spot. [1] The geographic distribution includes India, South America, and the south-eastern United States. [2]
Rusts are fungal plant pathogens of the order Pucciniales causing plant fungal diseases.
Blight refers to a specific symptom affecting plants in response to infection by a pathogenic organism.

Eyespot is an important fungal disease of wheat caused by the necrotrophic fungus Tapesia yallundae and Tapesia acuformis. It is also called Strawbreaker. Eyespot is more severe where wheat is grown continuously and when the weather is cool and moist. Treating crops against eyespot with fungicide costs millions to farmers and is complicated by the pathogen becoming resistant to the more commonly used fungicides. Severe cases of the disease can reduce yield by up to 40%. It is most common in temperate regions such as North and South America, Europe, Australia, New Zealand and Africa.
Actinidia deliciosa, the fuzzy kiwifruit, is a fruiting vine native to Southern China. Other species of Actinidia are also found in China and range east to Japan and north into southern areas of Russian Far East. This species grows naturally at altitudes between 600 and 2,000 m.
Phomopsis cane and leaf spot occurs wherever grapes are grown. Phomopsis cane and leaf spot is more severe in grape-growing regions characterized by a humid temperate climate through the growing season. Crop losses up to 30% have been reported to be caused by Phomopsis cane and leaf spot.
Alternaria is a genus of Deuteromycetes fungi. All species are known as major plant pathogens. They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma. They are present in the human mycobiome and readily cause opportunistic infections in immunocompromised people such as AIDS patients.
Alternaria mali, also called alternaria blotch of apple, is a pathogenic fungus affecting plants. It is prevalent in the southern United States and elsewhere, and damages the leaves of infected apple trees.
Botryosphaeria dothidea is a plant pathogen that causes the formation of cankers on a wide variety of tree and shrub species. It has been reported on several hundred plant hosts and on all continents except Antarctica. B. dothidea was redefined in 2004, and some reports of its host range from prior to that time likely include species that have since been placed in another genus. Even so, B. dothidea has since been identified on a number of woody plants—including grape, mango, olive, eucalyptus, maple, and oak, among others—and is still expected to have a broad geographical distribution. While it is best known as a pathogen, the species has also been identified as an endophyte, existing in association with plant tissues on which disease symptoms were not observed. It can colonize some fruits, in addition to woody tissues.
Silver leaf is a fungal disease of trees caused by the fungal plant pathogen Chondrostereum purpureum. It attacks most species of the rose family Rosaceae, particularly the genus Prunus. The disease is progressive and often fatal. The common name is taken from the progressive silvering of leaves on affected branches. It is spread by airborne spores landing on freshly exposed sapwood. For this reason cherries and plums are pruned in summer, when spores are least likely to be present and when disease is visible. Silver Leaf can also happen on poming fruits like apples and pears. Plums are especially vulnerable.
Phyllachora pomigena is a plant pathogen responsible for Sooty blotch and flyspeck disease, a disease affecting apples and pears. It appears as a brown or black blotch on the fruit. Spots may coalesce to cover the entire fruit. During the summer these diseases develop during cool rainy weather, particularly in dense, unpruned trees with poor air circulation. Although unsightly, the fruit is still edible. The sooty blotch will wipe off of the fruit.
Mucor piriformis is a plant pathogen that causes a soft rot of several fruits known as Mucor rot. Infection of its host fruits, such as apples and pears, takes place post-harvest. The fungi can also infect citrus fruits.
Cadophora malorum is a saprophytic plant pathogen that causes side rot in apple and pear and can also cause disease on asparagus and kiwifruit. C. malorum has been found parasitizing shrimp and other fungal species in the extreme environments of the Mid-Atlantic Ridge, and can be categorized as a halophilic psychrotrophic fungus and a marine fungus.
Schizothyrium pomi is a plant pathogen of the sooty blotch and flyspeck complex, infecting apple, pear and citrus trees and carnations.
Pythium spinosum is a plant pathogen infecting a wide variety of crops. Hosts observed to be infected include rice in Taiwan, Primula, Impatiens, soil in Florida, Cucumis melo in South Korea, and soybeans in Arkansas USA, China, and Indiana USA.
Asperisporium caricae is an ascomycete fungus that is a plant pathogen, found in North and South America. It is responsible for the black spot disease on papaya trees. It affects generally leaves and fruits at any time. Sporodochia of Asperisporium caricae was growing under side of leaf, dark blackish brown to black, stroma well-developed, erumpent.
Gymnosporangium sabinae is a species of rust fungus in the subdivision Pucciniomycotina. Known as pear rust, European pear rust, or pear trellis rust, it is a heteroecious plant pathogen with Juniperus sabina as the main primary (telial) host and Pyrus communis as the main secondary (aecial) host.
A fungus is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae and either Protista or Protozoa and Chromista.
Serendipita indica is a fungal species of the order Sebacinales. It is an endophytic root-colonising species, discovered from orchid plants in the Thar desert in Rajasthan, India by Prof. Ajit Verma and group, School of Life Sciences, Jawaharlal Nehru University, New Delhi. The fungus has typical pear-shaped chlamydospores. S. indica can be easily grown on various substrates. It has been found to promote plant growth during its mutualistic symbiotic relationship with a wide variety of plants. Experiments have shown that S. indica increases the resistance of colonized plants against fungal pathogens. It has also been found in experiments with barley that S. indica-inoculated plants are tolerant to salt stress and more resistant to root pathogens. S. indica-infested roots also show antioxidant capacity. The fungus also induces systemic disease resistance in plants. S. indica was found to require host cell death for proliferation during mutualistic symbiosis in barley. Its genome has been sequenced and was published in 2011.
Lichtheimia corymbifera is a thermophilic fungus in the phylum Zygomycota. It normally lives as a saprotrophic mold, but can also be an opportunistic pathogen known to cause pulmonary, CNS, rhinocerebral, or cutaneous infections in animals and humans with impaired immunity.
