Organic farming system emphasis on sustainable development of agriculture, the traditional agriculture system was much akin to the organic system but modernization of agriculture made a shift to this trend. Field experiments were conducted during kharif (Rain fed) 2013 and 2014 to develop a suitable organic module to manage these diseases and improve productivity of cluster bean. The module consisting of soil application of Neem Cake 2 q/ha + T. viride 2 kg/ha incubated on 100 kg FYM + Foliar spray of Neem Oil 2% and alternate foliar application of 1st Neem oil + 2nd cow dung + 3rd indigenous pesticide @ 35, 50, 65 DAS significantly reduced the maximum incidence of foliar diseases, and increased the yield attributes and yield of cluster bean. Two year pooled data under field conditions revealed that lowest powdery mildew (PDI 13.1), Blight complex (PDI 18.0) and maximum seed yield (743 kg ha-1) was recorded with the application of afore said module, as compared to un-treated control with PDI 60.3 and 73.6, respectively and seed yield 428 kg ha-1 . This organic module resulted in 1.95 B: C ratio over untreated control.
