Oidium (genus)
''Oidium'' is a genus of Deuteromycetes, where traditionally most anamorphs of the order Erysiphales are included. Most of them are plant pathogens causing different forms of powdery mildew, for example: *''Oidium alphitoides'' (= ''O. quercinum'') = '' Microsphaera alphitoides'' (on oaks) *'' Oidium anacardii'' (= ''Acrosporium anacardii'') (on cashew) *'' Oidium arachidis'' (on peanut) *''Oidium asteris-punicei'' (= ''Erysiphe cichoracearum'') (on mangos) *''Oidium balsamii'' = '' Erysiphe verbasci'' (on mulleins) *''Oidium begoniae'' (=''O.cyclaminis'', ''O.lini'', ''O.violae'') = ''Erysiphe polyphaga'' (on ''Valerianella'', ''Calluna'' and '' Erica'') *''Oidium candicans'' (= ''Monilia candicans'') *''Oidium caricae'' (on papayas) *''Oidium caricae-papayae'' (on papayas) *''Oidium caricicola'' (on papayas) *''Oidium chrysanthemi'' = ''Erysiphe cichoracearum'' (on numerous plant species, especially Asteraceae) *'' Oidium carpini'' *'' Oidium chartarum'' (= ''Torula chartarum ...

Oidium (spore)
An oidium (plural: oidia) is an asexually produced fungal spore that (in contrast to conidia) is presumed not to constitute the main reproductive preoccupation of the fungus at that time. The hypha breaks up into component cells/ small pieces and develop into spores. Oidia cannot survive in unfavourable conditions.

Uncinula Necator
''Uncinula necator'' (syn. ''Erysiphe necator'') is a fungus that causes powdery mildew of grape. It is a common pathogen of Vitis species, including the wine grape, ''Vitis vinifera''. The fungus is believed to have originated in North America. European varieties of ''Vitis vinifera'' are more or less susceptible to this fungus. ''Uncinula necator'' infects all green tissue on the grapevine, including leaves and young berries. It can cause crop loss and poor wine quality if untreated. The sexual stage of this pathogen requires free moisture to release ascospores from its cleistothecia in the spring. However, free moisture is not needed for secondary spread via conidia; high atmospheric humidity is sufficient. Its anamorph is called ''Oidium tuckeri''. It produces common odors such as 1-octen-3-one and (Z)- 1,5-octadien-3-one. This mildew can be treated with sulfur or fungicides; however resistance to several chemical classes such as Benomyl, the DMIs, and Strobilurins has ...
