Efficacy of Antagonists on Germination and Root Rot of Blackgram

Germination of blackgram seeds was significantly higher in Trichoderma viride + T. harzianum soil amendment 30 days before sowing and was on par with T. viride and T. harzianum applied individually. When added at the time or sowing, maximum germination was obtained in T. viride + T. harzianum soil amendment, and, was on par with T. harzianum soil amendment. There was significant reduction in the incidence of root rot when T. viride + T. harzianum was amended to soil either 30 days before sowing or at the time of sowing followed by T. harzianum soil amendment.
