Nine isolates of Trichoderma spp. were isolated from different agro- ecological regions of Nepal viz; Jumla, Palpa, Chitwan, Tarahara, Banke, Illam and Salyan and screened against Sclerotium rolfsii Sacc. Adreded soil borne phytopathogen causing collar rot of chickpea in chickpea; In-vitro efficacy of nine fungal antagonist (Trichoderma spp.) against Sclerotium rolfsii were screened. Pot experiment was done to find out the effective management of S. rolfsi through Tricoderma using different methods i.e. Seed treatment, soil drenching and soil application. All the tested isolates of Trichoderma spp. were found effective on mycelial growth inhibition and sclerotial parasitization of S. rolfsii. Trichoderma isolated from Palpa district showed maximum growth inhibition (%) of pathogen periodically after 48(93.78%), 72(96.00%), 96(97.96%) and 120(100.00%) hours of inoculation. Parasitized sclerotium showed minimum sclerotial germination on agar plates. Moreover, Trichoderma species isolated from Palpa districts showed second best percent mycelial growth inhibition periodically at 72(25.00%), 120(29.16%), 168(29.16%) and 216(29.16%).In pot experiment at 40 days after sowing, Seedling height was maximum in soil drenching with 30g per 100ml of water (22.27cm) and Mortality percentage of seedlings was least or highest disease control was observed in seed treated with 109cfu/ml (0.000%).

An in vitro and field experiments for two consecutive years were conducted at Bangladesh Institute of Nuclear Agriculture, Mymensingh, aiming to investigate the efficacy of Trichoderma harzianum against Sclerotium rolfsii causing collar rot disease of soybean and chickpea. In in vitro the antagonistic activity of T. harzianum against S. rolfsii was observed through dual culture. In field experiment Trichoderma was applied as soil treatment and seed treatment. The percent inhibition of S. rolfsii induced by T. harzianum was found upto 78.9% in in vitro. The maximum reduction of collar rot disease incidence over control was 82.4% in soybean and 77.6% in chickpea which was recorded in the plot where T. harzianum was applied in the soil. The highest seed germination: 86.3% in soybean and 84.8% in chickpea, maximum fresh shoot weight: 94.5 g plant-1 in soybean, 62.5 g plant-1 in chickpea, maximum fresh root weight: 10.7 g plant-1 in soybean, 9.3 g plant-1 in chickpea and the highest yield: 2830 kg ha-1 in soybean, 1836 kg ha-1 in chickpea were obtained by the application of Trichoderma in soil. The study indicated that the tested isolate of T. harzianum had potential in controlling collar rot disease of soybean and chickpea. For the reduction of collar rot incidence application of T. harzianum in soil was found more effective than seed treatment.
