abstract
The study was undertaken to experiment on the management of Stem Rot, Sclerotium oryzae in rice by summer deep ploughing, green manure in situ, wet seed treatment with carbendazim @ 1g/l of water, nursery protection with carbofuran @1 kg, application of cartap hydrochloride @8kg per acre, spraying of chlorantraniliprole @ 60 ml/acre 10 days before booting, spraying of propiconazole @1ml/lit twice at maximum tillering and panicle initiation was done in 5 locations of Bhadradri Kothagudem district of Telangana during Kharif 2018 and 2019. Later in addition technology refinement treatment i.e. spraying of validamycin 2ml/l twice at 15 days interval and trifloxystrobin + tebuconazole @ 0.4g/l was done during Kharif 2019. The disease incidence was least in technology refinement treatment i.e. 5.7 per cent during Kharif 2019. The cost benefit ratio (BC Ratio) was higher in technology assessment plots with 2.5:1 and 2.3:1 whereas BC ratio was lower comparatively in farmers practiced plots with 1.8: 1 and 1.9:1 in corresponding Kharif 2018 and 2019 respectively.
