ABSTRACT

Seed treatment with commercial formulations of bio-control agents viz., Trichoderma viride, Pseudomonas fluorescens and thiram as check were evaluated against Macrophomina phaseolina causing charcoal rot of sorghum. Seed treatment with T. viride (Co isolate) @ 4g/kg of seed recorded average charcoal rot percentage of 17.7%, 11.8%, and 10% in cultivars M 35-1, GRS1 and 9–13, respectively followed by P. f1uorescens (CO) recording 23.4, 13.1 and 9.1 per cent respectively. The other charcoal rot parameters MNC and MLS were minimum in these two treatments. Thus, the study indicated that seed treatment with bio-control agents is the best options in the absence of complete host plant resistance for the management of charcoal rot disease of sorghum.
