Efficacy of fungicides on dry root rot of chickpea under field condition

An experiment was conducted on efficacy of fungicides of chickpea dry root rot incited by Rhizoctonia bataticola (Taub.) Butler has been emerging as a potential threat in last decades for successful and profitable chickpea cultivation because the pathogen is soil borne nature. The present investigation conducted at chickpea dry root rot hot spot area under natural conditioning Harda district of Madhya Pradesh during rabi 2017-18. The data evident that the spraying of Trifloxystrobin 25% + Tebuconazole 50% @ 500g ha-1 proven most effective for reducing dry root rot incidence in chickpea followed by Propiconozole 25 EC@ 500g ha-1, Tebuconazole 250 EC (25.9% W/W) @625 ml ha-1, Metalaxyl 4%+ Mancozeb 64% @ 1000g ha-1, and Pyraclostrobin 20 WG @500g ha-1 compare to control, while, the incidence of dry root rot noticed minimum 1.50, 2.25, 3.75, 9.50 and 11.50 per cent respectively, although, the incidence 60.75 per cent chickpea dry root rot was noticed in control in respect to management of the diseases, while, Pyraclostrobin 20 WG was found least effective in minimizing the disease incidence. The grain yield maximum 23.25 q ha-1, while, least grain yield 8.75 q ha-1 was harvested in control. Apart from this, the Benefit Cost Ratio 1:2.76 and 1:1.18 was noticed in Trifloxystrobin 25% + Tebuconazole 50% and control treatment, respectively.
