	Microsphaera Diffusa ''Microsphaera diffusa'' is a plant pathogen that is known to cause powdery mildew on soybean The soybean, soy bean, or soya bean (''Glycine max'') is a species of legume native to East Asia, widely grown for its edible bean. Soy is a staple crop, the world's most grown legume, and an important animal feed. Soy is a key source o ...s. Importance Powdery mildew is a significant pathogen of soybeans and tends to cause epidemics about every 10–15 years in Wisconsin. The first epidemic there was observed in 1975 and several have occurred since. When 82% of the soybean leaf area is covered by ''M. diffusa'', photosynthetic and transpiration rates are less than half of normal soybeans, thus affecting soybean yield. Different studies have found varying amounts of yield reduction due to powdery mildew. In Illinois, measured yield losses ranged up to 14 percent. Studies from Iowa recorded yield losses of up to an estimated 10 bushels per acre. In Wisconsin, yield loss w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Powdery Mildew Powdery mildew is a fungus, fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of Ascomycota, ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as the signs of the causal pathogen are quite distinctive. Infected plants display white powdery spots on the leaves and stems. This mycelial layer may quickly spread to cover all of the leaves. The lower leaves are the most affected, but the mildew can appear on any above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. Powdery mildew grows well in environments with high humidity and moderate temperatures; greenhouses provide an ideal moist, temperate environment for the spread of the disease. This causes harm to agricultural and horticultural practices where powdery mildew may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Erysiphales Erysiphales are an order of ascomycete fungi. The order contains one family, Erysiphaceae. Many of them cause plant diseases called powdery mildew. Systematics The order contains one family (Erysiphaceae), 28 genera and around 1000 species. Many imperfect fungi (fungi whose sexual reproduction is unknown) belong here, especially the genus '' Oidium''. Recent molecular data have revealed the existence of six main evolutionary lineages. Clade 1 consists of '' Erysiphe'', '' Microsphaera'', and '' Uncinula'', all of which have an ''Oidium'' subgenus ''Pseudoidium'' mitosporic state. Clade 2 consists of '' Erysiphe galeopsidis'' and '' Erysiphe cumminsiana'' ( anamorphs in ''Oidium'' subgenus ''Striatoidium''). Clade 3 consists of ''Erysiphe'' species with anamorphs in ''Oidium'' subgenus ''Reticuloidium''. Clade 4 consists of ''Leveillula'' and ''Phyllactinia'', which have ''Oidiopsis'' and ''Ovulariopsis'' mitosporic states, respectively. Clade 5 consists of '' Sphaerotheca'', ...
