Abstract:
Indian mustard [Brassica juncea (L.) Czern & Coss] is an important oilseed crop. Powdery mildew of mustard incited by Erysiphe cruciferarum (Opiz ex Junell) is the most important disease that causes a maximum reduction in yield and quality of mustard seed. A field experiment was carried out to know the effect of different fungicides against powdery mildew of mustard during Rabi season. Among the seven treatments, Tebuconazole 50 % + Trifloxystrobin 25% WG (0.1%), was observed highly superior over other fungicides and recorded a minimum of 8.33 per cent disease intensity (PDI) by decreasing 85.37 per cent disease intensity and maximum 13.62 q/ha yield. Myclobutanil (0.1%) was observed second best and recorded 12.73 per cent disease intensity and yield 12.32 q/ha.
