Rarely the Black Gram crop is affected by Powdery mildew and it is noticed by the presence of white powder deposits on the leaves. Leaf spot of Cercospora can be noticed by the presence of brown spots. The Powdery mildew and cercospora can be controlled by spraying 1% Bavistin solution. Harvesting of black gram crop Black gram (Vigna mungo (L.) Hepper) is the third most important pulse crop in India. Powdery mildew caused by Erysiphe polygoni DC is one of the major constraints in the production of black gram causing both qualitative and quantitative loss of grains. The fungus has very wide host range spread by air borne oidia and also produces the sexual fruiting bodies cleistothecia and difficult to.
