The antagonistic potential of forty four isolates of Trichoderma were evaluated in vitro against the most widely occurring soil borne plant pathogens viz., Macrophomina phaseolina, Rhizoctonia solani, Rhizoctonia bataticola and Sclerotium rolfsii to identify the most potential Trichoderma isolate. Maximum growth inhibition of M. phaseolina (81.11 %), R. solani (82.59 %) and S. rolfsii (76.67 %) was recorded by T. hamatum where as T. virens was most aggressive against R. bataticola (68.15 %) in dual culture technique.

Abstract


The antagonistic potential of forty four isolates of Trichoderma were evaluated in vitro against the most widely occurring soil borne plant pathogens viz., Macrophomina phaseolina, Rhizoctonia solani, Rhizoctonia bataticola and Sclerotium rolfsii to identify the most potential Trichoderma isolate. Maximum growth inhibition of M. phaseolina (81.11 %), R. solani (82.59 %) and S. rolfsii (76.67 %) was recorded by T. hamatum where as T. virens was most aggressive against R. bataticola (68.15 %) in dual culture technique.
