The present study was undertaken to analyze the effect of the native Trichoderma spp., isolated from the rhizosphere of ghost pepper (Capsicum chinense) against root rot caused by Rhizoctonia solani. Rhizospheric Trichoderma spp. were isolated from ghost pepper growing sites of Manipur and screened for their biocontrol potential against Rhizoctonia solani. Four fungal isolates were isolated and selected based on morphology and growth pattern. Molecular identification was carried out and an amplicon size of 262 bp were generated for fungus. Screening of the potent isolates showed variation on the radial growth of the pathogen, Rhizoctonia solani. Seven different substrates viz. Rice bran, Rice bran + Sugarcane juice (10%), Rice bran+Cowdung (1:1)+Jaggery (3%), Rice bran+ Cowdung (1:1)+Sugarcane juice (10%), Rice bran+Sugar (3%), Rice bran+ Mustard cake (1:1) + Jaggery (3%), Rice bran+ Mustard cake (1:1) + Sugarcane juice (10%) were evaluated for mass production of the most potent Trichoderma spp. Among the different substrate, highest population was recorded in rice bran + mustard cake (1:1) + sugarcane juice (10%) from CAU (13.33 x 108cfug-1) isolate at 30 days of incubation.
