Author(s): Manju Kumari and Mahabeer Singh
Abstract: All the bio agents were found significantly inhibitory to the fungal growth as compared to control in vitro and in vivo. Antagonistic effect of of 2 Trichoderma strains (T. harzianum and Trichoderma viride), Pseudomonas fluorescens and T. harzianum + P. fluorescens against the collar rot disease-causing fungus A. niger, were studied in vitro and in vivo. Studied of relative efficacy of organic amendments with bio-agents field conditions also. Of all the 2 fungal and 1 bacterial biocontrol agents screened by dual culture technique. It was observed that T. harzianum inhibited maximum (81.66%) growth of test fungus, followed by T. viridae (66.94%) in vitro and in feild conditions observed T. harzianum + P. fluorescens was most effective (52.21%) followed by T. harzianum (45.73%). Thus, these findings indicated that biological control using bioagents can be exploited in the frame work of integrated disease management to manage the collar rot of groundnut incited by Aspergillus niger.
