Abstract: Chilli is an important vegetable crop that is severely affected by collar rot disease caused by Sclerotium rolfsii. Volatile and non-volatile substances secreted by biocontrol agents are very effective in the management of many fungal plant pathogens. The present study deal with in-vitro antagonistic efficacy of six Trichoderma isolates viz., Trichoderma ovalisporum, Trichoderma harzianum, Trichoderma koningiopsis, Trichoderma asperellum, Trichoderma atroviride and Tichoderma hypocrea against Sclerotium rolfsii tested by using poison food technique method. The results revealed that some isolates are very effective in reducing the mycelial growth of the pathogen. The volatile compounds secreted by Trichoderma asperellum showed 34.90% inhibition over control. However, the non-volatile compounds secreted by Trichoderma harzianum showed significant inhibition percentage of 16.08% and 41.57% at 7.5% and 15% concentration respectively. Trichoderma hypocrea and Trichoderma atroviride were found ineffective against the pathogen.
