Clade 6 consists of "Blumeria graminis", which has an "Oidium" subgenus "Oidium" mitosporic state. The vine ripens late and is susceptible to many grape diseases including oidium. The vine performs well in drought conditions but is susceptible to oidium and peronospora. In the mid-nineteenth century oidium struck. It was followed by a fungal disease called powdery mildew (Oidium). Clade 3 consists of "Erysiphe" species with anamorphs in "Oidium" subgenus "Reticuloidium". It also has some sensitivity to downy mildew and oidium. Only some cultivars are severely susceptible to mildew disease ("Oidium ceratoniae" C.). Its anamorph is called Oidium tuckeri. The defunct genera "Oidium" and "Monilia" were used to represent the genus "Candida". It does have some susceptibility to oidium though. Sauvignon vert is a late budding vine with high sensitivity to downy mildew and oidium. Oidium tingitaninum is a plant pathogen affecting citrus. Powdery mildew (oidium) struck in 1852 and Phylloxera in 1863. The vine is highly resistance to peronospora but has some susceptibility to oidium.
