Abstract:
Sesame Phytophthora blight disease is one of the major constraints for successful cultivation and it may reported to cause substantially high yield loss. Integrated Disease Management (IDM) practices, found suitable against Phytophthora blight, developed and evaluated elsewhere, are here by tested and validated as IDM module with slight modifications as per local requirement. This is basically to demonstrate the benefit of good available technology to farmers as on farm trials (OFT). The comparative efficacy of four different modules were incredibly convincing for the farmers. It was realized that all three modules testes were significantly superior over prevailing farmer‘s practice (Module-1). Module-4 having Seed Treatment, Soil treatment with bio-agent and foliar spray of metalaxyl + mancozeb at early onset of disease found most effective in reducing disease incidence (86.21%) which is an average of three crop season. The yield increase (36.05%), net return (Rs. 7439.75) and benefit- cost ratio for the module four were very favorable and encouraging. Module -3 was found to be the next best. The modules were improving production and yield parameters that to without imposing any drastic input burden to farmers, as evidenced by cost and benefit estimates of our study. Hence it can be concluded that Module-4 may be considered for improved sustainable package of practice for Pytophthora blight management of Sesame.
