Abstract

Two stable mutants, one each of Trichoderma viride (TvM₁) and Trichoderma harzianum (ThM₁), obtained through gamma radiation were tested for their compatibility with different pesticides in order to fit them in integrated disease management for the control of fusarial wilt of chilli. Both the fungal mutants showed high compatibility carbendazim (0.1%), fipronil (0.2%), imidacloprid (0.025%) and fluchloralin (0.33%). TvM₄ showed compatibility with captan (0.25%), copper oxy chloride (0.15%), phosalone (0.1%) and butachlor (0.2%) and ThM₁, was compatible with mancozeb (0.125%) and phosalone (0.1%). Mancozeb (0.25%), copper oxy chloride (0.3%), dicofol (0.5%), pendimethalin (0.66%) and alachlor (0.4%) were found to be highly inhibitory to the radial growth of the mutants TvM₁ and ThM₁.
