Spot blotch caused by Bipolaris sorokiniana is the most devastating in India and several other countries. The disease also seed, soil, air borne in nature therefore seed were play role in disease development. Seed treatment is a simple and first step of disease management in seed borne diseases and methods can reduces disease intensity of wheat. In seed treatment out of nine fungicide with different concentrations . Raxil 060FS, Trifloxystrobin 500SC, Tebuconazole 2% DS, Trifloxystrobin + Tebuconazole 080 FS, Nativo (Trifloxystrobin 25% + Tebuconazole 50%) 75 WG, Flint (Trifloxystrobin) 75 WG, Vitavax, Neemexecel and Bioagent (T. harzianum) have been revealed that the seed treatment with fungicides and biocides significantly increased the germination percentage of wheat seed over the control except Nativo 75 WG and Trifloxystrobin + Tebuconazole 080 FS. In blotter paper method, The maximum germination with 100 per cent was recorded in the treatment of Trichoderma viride followed by Raxil , Tebuconazole 2% DS per cent and vitavax . Seed treatment with neem product (neemexel) gave the superior result(100%) over the control but inferior to other treatment and in regarding growth parameter, shoot length of wheat seedling with Trichoderma viride was best showing per cent increase over control followed by Raxil060FS (). The rest of the treatment were also showing increased trend of plant growth but not at par with T. viride. In case of glasshouse condition, the maximum with 99% seed germination was recorded in the treatment of Trichoderma viride followed by Raxil , Tebuconazole 2% DS , vitavax . The shoot length of wheat seedling was found maximum better under treatment with T. viride () representing on against cm in control which was followed by cm and cm in Raxil 060FS and Vitavax treated plant respectively. | Effect of seed treatment of fungicides and biocides against spot blotch of wheat caused by Bipolaris Sorokiniana
