Abstract

Field screening conducted during Kharif, 2008 and 2009 revealed that out of 31 genotypes of greengram, only 1 genotype ML 1299 and out of 14 genotypes of blackgram, only 3 genotypes viz, BS 2–3, IPU 02–43 and B 3-8-8 showed resistant or highly resistant response against multiple diseases including Cercospora leaf spot, web blight and powdery mildew. In another trial conducted for management of foliar diseases of greengram and blackgram through chemical revealed that two foliar sprays of propiconazole @ 0.1% at an interval of 8–10 days was most effective as it reduced severity of Cercospra leaf spot (85.77 and 80.10%), web blight (77.87 and 85.29%) and powdery mildew (100.00% each) with average yield of 9.08 and 8.83q/ha of greengram and blackgram, respectively.
