Efficacy of biocontrol agents, plant extracts and organic ammendment against blight, powdery mildew and wilt diseases in cumin

Field experiment was conducted to study the effect of the different organic modules for management of Alternaria blight Powdery mildew and wilt diseases of cumin (Cuminum cyminum L.).Treatment module comprising of seed treatment with Trichoderma herzeanum@8g/kg seed + three foliar spray of Azadirachtin @2ml/lit.at 45-60DAS+ 60-75DAS+and at 90-100 DAS was found significantly superior over control and gave maximum seed yield of cumin 5.76q/ha. in comparison to control which gave only 3.43q/ha. cumin seed yield.This organic module was found superior in respect to disease control and effectively controlled all three diseases and record minimum disease intensity of Alternaria blight(12.49%) Powdery mildew 14.93% and wilt (6.20%). Where as in control 26.33.% ,28.66% and12.28%disease intensity was observed respectively. This module gave the highest net return of Rs.28013 /over control.
