Abstract

A significant interaction between antagonistic soil micro-organisms and cotton cultivars influenced the development of disease symptoms by R. solani AG-4 in vivo. Two isolates of each of Trichoderma spp. and Gliocladium spp were selected from 50 different micro-organisms using a fast assay. Rhizoctonia solani (AG-4) was controlled successfully in the greenhouse when the biological agents were applied on autoclaved organic manure, but wheat bran or gel suspensions were not as efficacious. In field experiments, no significant differences were observed between the biological agents and nontreated control. Several other soil borne pathogens were isolated from diseased seedlings from the field in addition to R. solani AG-4.
