Abstract: (14831 Views)
Powdery mildew disease of beet, cause by the fungus Erysiphe polygoni, is highly epidemic on table beets which are mostly cultivated in cooler regions of Isfahan province. Severity of the disease in fodder beets is lower than that of table beets. Studies on this fungus revealed that there is ascocarp formation as yellow spots which then turned to light to dark brown and then to black spherical bodies on upper, lower and petiols of the leaves, at the end of the season. Asci contain ellipsoid ascospores . Disease symptoms, characters of the pathogen and methods of disease management are described.
