Microsphaera Diffusa
''Microsphaera diffusa'' is a plant pathogen. ''M. diffusa'' infections on soybeans are referred to as powdery mildew. Importance: Powdery mildew of soybeans is an important pathogen and tends to cause epidemics about every 10–15 years in Wisconsin. In 1975 the first epidemic there was observed and several have occurred since. Powdery mildew affects the soybean plants. 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 different amounts of yield reduction due to the powdery mildew. In Illinois, measured yield losses ranged up to 14 percent. From Iowa studies, measured yield losses were estimated up to 10 bushels per acre. In Wisconsin, the yield loss was up to 5 bushels per acre. And it's important to note that yield loss due to powdery mildew will be greater for soybeans planted late for a region compared to early-planted soyb ...

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 approximately 100 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'', ...

Powdery Mildew
Powdery mildew is a fungal disease that affects a wide range of plants. Powdery mildew diseases are caused by many different species of ascomycete fungi in the order Erysiphales. Powdery mildew is one of the easier plant diseases to identify, as its symptoms are quite distinctive. Infected plants display white powdery spots on the leaves and stems. 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 thrive in a greenhouse setting. In an agricultural or horticultural setting, the pathogen can be controlle ...
