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,

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

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.

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.

Powdery mildews were first recognized as white powdery appearance on the leaves of Humulus, Acer, Lamia, Galeopsis, and Lithospermum by plant pathogens infection as early as 1753 which was named as Mucor erysiphe. Initially powdery mildews were a fascinating subject of research for mycologists who reported several species of powdery mildews on ...

Closing the ranks to attack by powdery mildew
Trends in Plant Science, 2000Powdery mildews are among the most common plant diseases, infecting over 650 monocot and over 9000 dicot species. Analysis in domesticated barley and wild Arabidopsis has begun to unravel the genetic and molecular frameworks underlying the mechanisms of susceptibility and resistance to these biotrophic fungal pathogens.

Crucifers include very large group of oilseed Brassica species, and vegetable crops grown all over the world for quality vegetable oil and as vegetables apart from a source of fodder crops. The major oil yielding Brassica crops are: B. juncea (Mustard), B. napus (Rapeseed), B. carinata (Ethiopian mustard), B. rapa subsp.
