Seed spices have emerged as one of the important group of spice crop in India. The global demand estimated for seed spices crop is about 150000 tonnes, and India contributes 70,125 tonnes annually accounting to 47 % of the total world trade. The cultivation of seed spice crop suffers from major disease like stem gall (Protomyces macrosporus Unger). In this investigation the effect of seed treatment and foliar spray of bioagents Trichoderma viride, Pseudomonas fluorescens and fungicides like Carbendazim, Ridomil, Blitox-50, Hexaconazole and Propiconazole on the incidence of stem gall disease of coriander tested. The trial was conducted in a Randomized Block Design with three replications and eight treatments including check. Hexaconazole as seed treatment (0.2%) and foliar spray after 40,60 and 75 DAS (0.2%) is more effective treatment for management of stem gall disease of coriander than the seed treatment of biofungicides like Trichoderma viride (0.4%) and foliar spray of Trichoderma species (0.4%) after 40,60 and 75 days of sowing. Maximum seed yield in Hexaconazole and Propaconazole treatment was at par to each other. Maximum cost benefit ratio of 1:4.36 was observed in the seed treatment of IISR Trichoderma liquid formulation @ 0.4% + foliar spray at 40, 60 and 75 DAS @ 0.4%.
