Die-back and fruit rot diseases are major yield limiting factor in all chilli growing areas of India. Trichoderma species are commonly used as biological control agents against phytopathogenic fungi and represent differential capacity of antagonism. In the present investigation, the effect of seven native Trichoderma isolates from Madhya Pradesh was examined for management of chilli die back and fruit rot using seed treatment with three foliar sprays of respective isolate. Different isolates of Trichoderma spp. significantly inhibited the growth of Colletotrichum capsici causing die-back and fruit rot in chilli under confrontation assay and maximum inhibition of 39.29% was recorded by Trichoderma isolate T2(REWA) after 96 hrs of incubation period. In field conditions, among treatments with different Trichoderma isolates, it was observed that minimum PDI of 19.40% was recorded in seed treatment and three foliar sprays with T2 isolate of Trichoderma with maximum yield of 69.55q/ha. Among different fungicides evaluated, minimum PDI of 21.47% was recorded in foliar spray with propiconazole @0.1%. This was followed by foliar spray with Thiram + Carboxin @0.2% where 23.73 % PDI was recorded.
