Abstract:
Two years field experiment was conducted to see the effect of seed biopriming on incidence of Alternaria leaf spot in green gram at college farm, NMCA, NAU, Navsari. Seed biopriming with six different bioagents viz., T. viride, T. harzianum, T. fasciculatum P. fluorescens-I, P. fluorescens-II, P. Aeruginosa 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 Alternaria leaf blight by 46.54 to 55.81 Per cent over absolute control. The highest Per cent disease control was obtained in seed biopriming with T. harzianum (55.81 %) followed by T. viride (55.28%), P. aeruginosa (55.03%) and all the other treatments over control at 65 DAS. Thus, seed biopriming with T. harzianum, T. viride or P. aeruginosa @10 gm talc base formulation/kg seeds was recommended to manage Alternaria leaf spot significantly.
