Abstract:

Study to check the efficacy of seed treatment by bioagents on the seed germination and vigour by inhibiting the most dominant seed mycoflora (A. niger, Colletotrichum sp. and Fusarium sp.) of chilli variety GVC 111 was carried out by paper towel method in vitro. Treatment of seeds with T. harzianum+P. fluorescens (5+6g/kg seeds) and P. fluorescens (6g/kg seeds) found effective in seeds pretreated with A. niger, while T. harzianum+P. fluorescens (5+6g/kg seeds) and P. fluorescens+B. subtilis (6+6g/kg seeds) found effective in seeds pretreated with Colletotrichum sp. and P. fluorescens+B. subtilis (6+6g/kg seeds) and T. viride+P. fluorescens (5+6g/kg seeds) found effective in seeds pretreated with  Fusarium sp. However, overall results indicated that seed treatment with P. fluorescens+B. subtilis @ 6g + 6g/kg seeds and T. harzianum+P. fluorescens @ 5g + 6g/kg seeds proved very effective with higher seed germination, seedling length and vigour index in all pretreated seed mycoflora i.e, A. niger. Colletotrichum sp. and Fusarium sp.
