Erysiphe Heraclei
''Erysiphe heraclei'' is a plant pathogen that causes powdery mildew on several species including dill, carrot and parsley. History It was originally found in 1815, on the leaves of a species of ''Heracleum (plant), Heracleum'' in France. It was found in Australia in New South Wales in 2007 then it spread to Tasmania and South Australia in 2008. Importance ''Erysiphe heraclei'' is no different than your typical powdery mildew as it shares many of the important traits that make it a plant disease worth paying attention too. In the case of powdery mildew of carrots yield loss is a very typical result of an infection, as well as the reduction of the ability to mechanically pull carrots from the ground during harvest due to leaf damage."Vegetable Diseases Cornell", vegetablemdonline.ppath.cornell.edu, 2018, http://vegetablemdonline.ppath.cornell.edu/NewsArticles/Carrot_Powdery.html. Accessed 10 Dec 2018. The effects of yield lost are felt most with early infections, for carrots there ...

Erysiphe Cruciferarum
''Erysiphe cruciferarum'' is a plant pathology, plant pathogen of the family Erysiphaceae, which causes the main powdery mildew of crucifers, including on ''Brassica'' crops, such as cauliflower, cabbage, broccoli, and Brussels sprouts. ''E. cruciferarum'' is distributed worldwide, and is of particular concentration in continental Europe and the Indian subcontinent. ''E. cruciferarum'' is an Ascomycota, ascomycete fungus that has both sexual and asexual stages. It is also an obligate parasite that appears to have host specificity; for example, isolates from turnip will not infect Brussels sprout, and vice versa. While being a part of the family Erysiphaceae, it belongs to those members in which the conidia are formed singly and whose haustoria are multilobed. This species is also being evaluated as a potential biological control for the invasive plant garlic mustard. Signs and symptoms ''Erysiphe cruciferarum'' exhibits typical powdery mildew characteristics, appearing as small ...

Erysiphe Polygoni
''Erysiphe betae'' is a fungal plant pathogen. It is a form of powdery mildew that can affect crops of sugar beet A sugar beet is a plant whose root contains a high concentration of sucrose and that is grown commercially for sugar production. In plant breeding, it is known as the Altissima cultivar group of the common beet (''Beta vulgaris''). Together with ..., that could cause up to a 30% yield loss. The fungus occurs worldwide in all regions where sugar beet is grown and it also infects other edible crops, e.g. beetroot. Identification This pathogen is a strict obligated parasite, and therefore can only be identified when ''in planta''. Often to properly identify this pathogen, some form of microscopic analysis is needed when it is only found on one type of plant. This can be done through isolation and observation of cleistothecia, which are the product of sexual reproduction. Disease symptoms * Symptoms appear as dirty white, circular, floury patches on either sides of ...

Erysiphaceae
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'', ''P ...
