dc.description.abstractChickpea (Cicer arietinum L.) is an important pulse crop of India. Collar rot of chickpea caused by Sclerotium rolfsii is an important disease of chickpea. Fifty chickpea genotypes were evaluated under artificially inoculated pot condition during Rabi 2019-20. Out of 50 genotypes seven genotypes viz., C- 1769, C-1775, PDG-4, ICVT-181107, ICVT-181118, ICVT-181117 and Vijay were found moderately resistant and rest genotypes were found susceptible to highly susceptible. Six native fungal antagonists (Trichoderma spp.) were evaluated in vitro against S. rolfsii through dual culture and non-volatile (culture filtrate) techniques among them Trichoderma harzianum (TH2) found highly effective against the pathogen, which inhibited maximum growth of the pathogen 75.18% and 61.85% in both dual culture and culture filtrate techniques, respectively. Nine fungicides were evaluated in vitro against pathogen and Trichoderma harzianum at 50, 100, 500 and 1000 ppm, with a view to select suitable fungicides highly toxic against S. rolfsii at lower concentrations and less toxic to bioagent (Trichoderma harzianum). Amongst 9 fungicide four fungicides namely captan 70% + hexaconazole 5% WP (Taquat), penflufen 13.28% w/w + trifloxystrobin (Evergold), hexaconazole 5% SC (Contaf), tebuconazole 25.9%E.C (Folicur) found highly effective which inhibited 100% growth of pathogen at all tested concentrations i.e 50, 100, 500 and 1000 ppm. Out of 9 fungicides four fungicides namely propineb, mancozeb, captan 70% + hexaconazole 5% WP, and penflufen 13.28% w/w + trifloxystrobin found less inhibitory against Trichoderma harzianum at 50 to 1000 ppm concentrations. For Integrated disease management the effect of 10 different treatments comprising highly effective bioagent (Trichoderma harzianum) and a fungicide highly effective against pathogen at lower concentration and compatible with bioagent used as a seed treatment and soil application with organic amendments in various combinations was evaluated under pot and field conditions during Rabi 2019-20. Under pot condition the treatment in which seed treatment with captan 70% + hexaconazole 5% WP + soil application with Trichoderma harzianum enriched vermicompost found most effective and provided maximum germination (100%) and reduction (77.13%) in the incidence of collar rot over control. The same treatment in which seed treated with captan 70% + hexaconazole 5% WP + soil application with Trichoderma enriched vermicompost also found highly effective in reducing (72.81%) collar rot incidence and increasing yield (67.67%) over control.en_US
