Abstract: Field experiment was conducted to study the effect of the different organic modules for management of Alternaria blight and Powdery mildew diseases of Indian Mustard (Brassica juneca)(L.) Czern &Coss) Efficacy of different organic modules were also tested against aphid management in successful growing of organic mustard.Treatment module comprising of seed treatment with Trichoderma viride@8g/kg seed +foliar spray of Azadirachtin @3ml/lit.at 5-10DAS+Neem oil spray@2% at 10-20DAS+NSKE spray@5% at 30-40 DAS+cow urine spray@10% at 50-60DAS+milk whey spray @10% at 60-75 DAS was found significantly superior over control and gave maximum seed yield of mustard 13.65q/ha. in comparison to control which gave only 10.16q/ha. mustard seed yield.This organic module was found superior in respect to disease control also,and effectively controlled both the diseases and record minimum disease intensity of Alternaria blight(15.94%) and Powdery mildew 17.67%. Where as in control 38.32% and 48.15% disease intensity was observed respectively. This module gave the highest net return of Rs.23294/over control with maximum B:C ratio of 1.88,1.83 and 1.84 in year 2012-13 & 2013-14 &2014-15respectively.
