Abstract:

Collar rot caused by Sclerotium rolfsii Sacc. is one of the catastrophic diseases of brinjal causing in negligible yield loss globally. The present study investigated the effect of Bacillus spp. and Trichoderma spp. on the growth of collar rot pathogen S. rolfsii under in vitro. The highest disease incidence was noticed in Vilangudi village which recorded 42.4% followed by Thirumangalam village (39.5%) and least incidence was noticed in Kottampatty village (8.8%) of Madurai district in Tamil Nadu. Results showed that the mycelial growth of the S. rolfsii was significantly inhibited by the Trichoderma isolate T-AG with 84.44 per cent growth reduction followed by the Bacillus isolate B-VI with 55.55 per cent growth reduction.
