Abstract

An investigation was undertaken to test the effect of liquid formulation of Trichoderma asperellum against Fusarium wilt of chickpea. Oil based formulation delivers organism in a physiologically dormant state and does not encourage the growth of contaminants during storage. Paraffin oil, soybean oil and groundnut oil were used as carrier material for oil based liquid formulation of Trichoderma asperellum. The population density of T. asperellum found in paraffin oil was 28.67 × 108 CFU/ml at 30 days whereas at 180 days it was 18.00 × 108 CFU/ml. Paraffin oil was found significantly superior over soybean oil and groundnut oil. The effect on percent growth inhibition of Fusarium oxysporum f. sp. ciceri was 74.44 percent. Efficacy of liquid formulation on growth parameter of chickpea revealed that paraffin oil based formulation of T. asperellum with combined seed treatment and soil application effectively increased the germination percentage (92.50%, 91.67%), shoot length (38cm, 32.16cm
