Biocontrol Of Fusarium Udum Through Trichoderma

Abstract

Management of wilt of pigeonpea by soil application of fungicides are economically non-viable. The potential role of biocontrol agent, Trichoderma, in the management of many soil borne plant pathogens are well documented. Hence, eleven different isolates of Trichoderma were assessed in vitro for their efficacy against Fusarium udum. The local strain of Trichoderma was equally efficacious against all the Fusarium udum isolates. Soil application of talc based preparation of this potential isolates was proved better to its seed treatment. The highest reduction in wilt was resulted in talc based preparation of promising local strain of Trichoderma compared to market products.
