Three bioagents (Trichoderma viride, T.harzianum and Gliocladium virens) and five biopesticides (Achook, Neemgold, Wannis, Spictaf and Neemazal) were evaluated under in vitro and in vivo conditions against knowall.blog Colletotrichum lindemuthianum.All the three antagonistic fungi caused significant inhibition of mycelial growth, maximum being with T.

viride (69.21%) followed by T.harzianum (64.

20%).Among the biopesticides tested at four concentrations, Wanis applied @ 1000 ?l/ml caused maximum inhibition of click here 82.12 per cent followed by Spictaf (52.

85%).T.viride and Wanis @ 1000 ?l/ml were most effective in reducing the seed borne infection.

Integration of bioagents with Bavistin showed that disease can be effectively managed with seed dressing either with Bavistin or biopesticide followed by foliar treatment with fungicide or biopesticide.
