BIOLOGICAL CONTROL OF SOUTHERN STEM BLIGHT OF SOYBEAN (GLYCINE MAX (L.) MERRILL) BY THE ELECTED TRICHODERMA

SUBHASH CHANDRA

ABSTRACT:

Trichoderma species Sclerotium rolfsii is an important stem disease pathogen and responsible for southern stem blight disease of Soybean. Sclerotium rolfsii were southern stem blight of Soybean Soybean , Sclerotium rolfsii have been reported as most potential biocontrol agents against several plant pathogens. The mass cultures of selected Trichoderma species and the test pathogen, S prepared on barley grain. The seed of susceptible variety of Soybean (NRC 7) were sown separately in the treated and control pots. Effect of the Trichoderma species amended in natural soil on per cent disease control of showed that the per cent mortality in plants was 92.2% in control but it was highly reduced in treatment. Amongst the antagonists, T. harzianum BHU showed maximum disease control (83.0 %) at 3% concentration but it was insignificant with T.viride 1.
