Integrated management of Fusarium wilt by combined soil application and seed dressing formulations of Trichoderma species to increase grain yield of chickpea
International Journal of Pest Management 59 (1), 47-54
Abstract: Wilt caused by the fungus Fusarium oxysporum f. sp. ciceris adversely affects the productivity of cultivated chickpea. For the management of this disease, seed and soil application formulations developed from another fungus, Trichoderma species, were evaluated. In pot experiments, T. harzianum-based formulations Pusa 5SD for seed dressing and Pusa Biopellet (PBP) 10G and Pusa Biogranule (PBG) 5 for soil application, and T. viride-based formulations Pusa 5SD for seed dressing and PBP 4G and PBG 4 for soil application, were found to be highly effective against the disease. A combination of PBP 4G (T. viride) for soil application and Pusa 5SD (T. harzianum) for seed treatment together with a fungicide, carboxin, provided the highest seed germination, shoot and root lengths and grain yield with the lowest incidence of wilt in chickpea under field conditions. Individually, soil application of PBP 4G, and seed treatment with Pusa 5SD were effective in reducing the incidence of wilt and increasing the grain yield of chickpea, but their effectiveness was greater when applied as a combination. Thus, combined application of the formulations of two different species of Trichoderma in two modes of application is recommended for the management of chickpea wilt.
