      Abstract

      Protection of chilli seedlings against Rhizoctonia damping-off by Plant Growth Promotion Fungi (PGPF) i.e.: Penicillium, Fusarium, Phoma, and sterile fungi were investigated in laboratory and greenhouse studies. The PGPF failed to show antagonistic interaction when grown in dual cultura on agar media with Rhizoctonia solani, causing damping-off disease. AllPGPF isolates did not inhibit the growth of Rhizoctonia solani. Treatment of chili seedlings with PGPF for 10 days and then the treated chili roots were surface sterilized with 70% ethanol for 30 sec. When the treated seedlings were replanted and subsequently inoculated with pathogen, however, the protective capability against R. Solani was srill maintained. Seedlings treated with Penicillium, Fusarium, Phoma, and sterile fungi reduced disease severity range from 30.0-95.9%; 32.6-71.4%; 16,3-65.3%; 69.4-95.9%, respectively. These results suggest that the mechannism of protection in this system might be induced resistance.
