To evaluate efficacy of the native isolates of Trichoderma species which promote the growth of chilli and to manage anthracnose disease under in vitro and field conditions. The dominant pathogen, which causes anthracnose of chilli is Colletotrichum capsici. Four native Trichoderma antagonists were isolated from rhizosphere soils of different healthy crops like Black gram, Green gram, Ground nut and Chilli from SHUATS, Central Research Farm Allahabad. Under in vitro conditions, the results revealed that Trichoderma viride isolate 1 was found to be effectively inhibit the radial mycelial growth of the pathogen (by 76.45%) when compared to all other isolates. Under field conditions, the minimum disease intensity (%) was recorded in Trichoderma viride isolate 1 + Trichoderma harzianum isolate 2 which was applied combinely as seed + soil treatment (36.33%).
