Actinomycetes were tested for their antagonistic activity against Fusarium udum and Macrophomina phaseolina under in vitro condition. Among the tested isolates of Actinomycetes AC (5) reported highest 82.85 per cent reduction of mycelial growth of Fusarium udum and 85.13 per cent reduction of mycelial growth of Macrophomina phaseolina. In the field experiment, five treatments were tested for the management of wilt and dry ischolar_main rot disease, T3- ST+ SA with Actinomycetes (AC 5) significantly recorded 71.92 and 70.38 per cent reduction of the wilt and dry ischolar_main rot diseases, respectively. These biocontrol agents were used an alternative to the chemical fungicide for controlling the wilt and dry ischolar_main rot incidence and enhanced the plant growth parameters and there by increased yield in redgram.

Among the tested isolates of Actinomycetes AC (5) reported highest 82.85 per cent reduction of mycelial growth of Fusarium udum and 85.13 per cent reduction of mycelial growth of Macrophomina phaseolina.
