Management of Seed Borne Mycoflora of Wheat (Triticum Aestivum L.) Using Fungicides and Bioagent

The present investigation was carried out on the “Studies of Seed borne Mycoflora of Wheat (Triticum aestivum L.)”, with a view to assess seed borne mycoflora associated with the seeds of wheat, their effect on seed germination and seedling vigour index, effects of fungicides and bioagents on seed borne mycoflora, seed germination and seedling vigour index All the isolated pathogens were found pathogenic to wheat resulting into reduction in seed germination and seedling vigour index. The seed borne mycoflora viz., Aspergillus falvus, Aspergillus niger, Alternaria alternata, Fusarium oxysporum and Curvularia lunata were found more dominant and damaging. Among the treatments of fungicides and bioagents fungicidal seed treatments were found significantly superior in reducing seedborne mycoflora, increasing seed germination and seedling vigour index. Among fungicides Tebuconazole @ 50 % + Tryfloxystrobin @ 25% WG @ 0.1% were found most effective against Aspergillus niger, Aspergilus flavus and Fusarium oxysporum, whereas Carboxin 37.5% + Thiram 37.5% DS @ 0.3% were found most effective against Curvualria lunata and Alternaria alternata. Among bioagents MPKV Fungal Consortium @ 10 gm kg-1 seed were found most effective against all detected seed mycoflora of wheat.
