Title: Efficacy of fungicides and biocontrol agents against Fusarium oxysporum f.sp. ciceri causing wilt of chickpea.
Abstract: Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri is a serious threat to its successful cultivation. Six fungicides both non systemic and systemic were evaluated against the pathogen under laboratory conditions. Thiram, mancozeb and baycor at 250, 500, 1,000, 2,000, 3,000 ppm and three systemic fungicides were evaluated at 50, 100, 250, 500 and 1,000 ppm concentrations respectively, two antagonistic fungi viz., Trichoderma harzianum (TH-CICR), Trichoderma viride (TV-97) and bacterial biocontrol agents viz., Pseudomas fluorescens (PF-1) and Bacillus subtilis (B-8) were evaluated for their antagonistic effect against Fusarium oxysporum f.sp. ciceri in vitro by dual culture test. Among the non-systemic fungicides tested, thiram inhibited maximum growth of 78.14% at 3,000 ppm. Among systemic fungicides evaluated, carbendazim and prochloraz were the best, which gave cent per cent inhibition of mycelial growth at 100 ppm concentration. Among fungal antagonists maximum inhibition was observed in Trichoderma harzianum (83.33%) followed by Trichoderma viride (75.66%) and among bacterial antagonists maximum inhibition was observed in Bacillus subtilis (76.66%)
