Abstract:
Two year’s field experiment was conducted to see the effect of seed biopriming on incidence of leaf blight in black gram at college farm, NMCA, NAU, Navsari. Seed biopriming with five different bioagents viz., T. viride, T. harzianum, T. virens, P. fluorescens and B. subtilis were taken as bioprimed treatments while, hydroprimed seeds and untreated seeds were acted as treated and absolute control. Data on average Per cent disease control was taken in present experiment. All the treatments were found to be effective in reducing the leaf blight over control. The highest Per cent disease control was obtained in seed biopriming with T. harzianum (57.14%) followed by T. viride (53.03%), P. fluorescens (50.00%) and all the other treatments over control at 65 DAS. Thus, seed biopriming with T. harzianum, T. viride or P. fluorescens @10 gm talc base formulation/kg seeds was recommended to manage leaf blight significantly.
