Mycologia, 1979
Throughout the temperate zones of the world, on many different kinds of plants, there occurs a whitish fungus growth of the powdery mildew fungi (Figs. 26-1,-3,-6). These fungi, which comprise the family Erysiphaceae, are all obligate parasites and all but a few are ectoparasites.

A review of fungal antagonists of powdery mildews and their potential as biocontrol agents [PDF]
Pest Management Science, 2003 There are approximately 40 fungal species that have so far been reported as natural antagonists of powdery mildews or have been tested as their potential biocontrol agents.

Live and let die – Arabidopsis nonhost resistance to powdery mildews [PDF]
European Journal of Cell Biology, 2010 The term "nonhost resistance" (NHR) describes the phenomenon that an entire plant species is resistant to all genetic variants of a non-adapted pathogen species.

Plant Pathology, 1988
A powdery mildew ( Erysiphe sp.) occurred on greenhouse‐grown tomato crops in southern England in 1987. White pustules appeared on the upper surfaces of leaves of affected crops and only rarely on the under surfaces. In greenhouse experiments, stems were very severely affected.

Nature, 1946
POWDERY mildew on potato was first recorded in Great Britain in 1932, when the oidial stage was found on the leaves of seedling potatoes in a glasshouse at Cambridge1. It was again observed at Cambridge in the late summer of 1945, and a field survey was made to determine its prevalence. The mildew was found not only on seedling plants in the greenhouse,

Mycologia, 1940
The fungus belongs to the genus Uncinula. No powdery mildew has ever been reported on this plant, and the fungus appears to be different from any that the writer has seen described. It is characterized by its exceedingly long appendages, four or five times as long as the diameter of the perithecium.

Conidial germination patterns in powdery mildews
Mycological Research, 2009Four conidial germination types namely, polygoni (syn. Pseudoidium), cichoracearum (syn. Reticuloidium), pannosa (syn. Fibroidium) and fuliginea (syn. Magnicellulatae) are commonly used as an aid in the identification of the Oidium anamorphs of powdery mildews. However, results of germination tests and a survey of the literature showed that these types

The powdery mildew of crucifers shows its symptoms on aerial parts of host plants in the form of white to dirty white circular floury patches on leaves, stems, inflorescence, and siliquae. These floury patches increase in size, and coalesce to cover entire aerial parts of the plant with the increase in atmospheric temperature.
