Chickpea (Cicer arietinum L.) is grown on an average area of about 16401 ha in the Dangs district of South Gujarat per year. Severe incidence (10 to 40%) of wilt caused by Fusarium oxysporum f. sp. ciceris is one of the important constraints in the production of Chickpea in the Dangs. Since recent past The Dangs district of South Gujarat was declared as organic district and thus, afield experiment on biological management of chickpea wilt was formulated and conducted for three years. Two bio agents viz., T. viride 1.5% WP (2 x 10? cfu/g) (IIHR strain) and P. fluorescence 1.5% liquid form (1 x 10? cfu / ml) (NAU strain) were used as seed treatment and soil application. Among all the treatments, maximum disease control and grain production was reported in the seed treatment of T.viride @ 10g/kg of seeds + two soil applications of T.viride @ 2.5 kg /ha in 250 kg FYM at sowing and at 50% flowering with minimum wilt incidence (5.46 %)and highest grain yield (2513 kg/ ha) followed by the seed treatment of P. fluorescence @ 10 ml / kg of seeds + two soil applications of Pseudomonas fluorescence @ 2.5 l /ha in 250 kg FYM at sowing and at 50% flowering with the wilt incidence of (5.51 %) and highest grain yield (2471 kg / ha) over all the other treatment and control with positive effect on average plant height (cm), average numbers of branches/plant, average numbers of pods/plant, average numbers of root nodules/plant bio agent cfu /gm soil at harvest with high cost benefit ratio
