Management of Fungal Foliar Diseases of Blackgram

摘要

A field experiment was conducted at Agricultural College farm, Bapatla during late rabi, 2016-17 to study the efficacy of eight fungicides on fungal foliar diseases of blackgram and on yield parameters. Foliar spray with Azoxystrobin @ 0.05% was foundsuperior in reducing the Corynespora leaf spot (53.52% PDI) and Cercospora leaf spot (36.66% PDI). Foliar spray of trifloxystrobin + tebuconazole @ 0.05% combination found superior in reducing the powdery mildew (PDI-0%). Highest seed yield (9.33 q/ha),lowest discoloured seed (17%) and lowest shrivelled seed (4.67%) were recorded by foliar spray with Azoxystrobin @ 0.05%.
