Abstract

Chickpea wilt incited by Fusarium oxysporum f. sp. ciceris is one of the severe diseases causes heavy losses (20-100%) depending upon stage of infection and wilting. Minimizing this disease can only be accomplished by careful crop management. Biological control is currently being painstaking for an increasing number of crops and managed ecosystems as the crucial technique of pest control. In this context an investigation was conducted to diminish wilt of chickpea by use of integrated disease management. It was observed that in vitro condition (dual culture technique) Trichoderma viride was highest inhibiting the growth of Fusarium oxysporum f. sp. ciceris at the ratio 1:4 followed by 1:2 and 1:1 in poisoned food technique maximum inhibition under field condition was obtained by 0.3% followed by 0.2 and 0.1%, doses of carbendazim. After that carbendazim it was neem cake at concentrations 7% followed by 5 and 3% in that order which give maximum inhibition of test pathogen under field condition. Lowest percentage of incidence of wilt (19.0%) was found with T. viride (T2) followed by carbendazim (21.0%), neem cake (42.6%), carbendazim+neem cake (45.2%), carbendazim+T. viride (47.2%), neem cake+T. viride (48.2%). Pot culture studies revealed that the soil application of T. viride (4 g kg-1) was found most effective treatment in reducing the incidence of chickpea wilt. Thus, chickpea wilt could be managed by the integration of various practices like, seed treatment with chemicals, seed and soil application of bioagents and amendment of soils with neem cakes.
