Resistance to Erysiphe polygoni of Red Clover Infected with Bean Yellow Mosaic Virus.
The development of Erysiphe polygoni on leaves of red clover was retarded by poor infection with bean yellow mosaic virus. Conidia germinated on leaves infected with the virus but disintegrated following necrosis of the leaf tissue in the immediate area of the germinating conidia.
