Assessment of IDM modules with some fungicides for whip smut of sugarcane in Chhattisgarh

Abstract

Among the fungal diseases of sugarcane whip smut (Ustilago scitaminea) is the most serious and widely spread disease of sugarcane and causes a significant reduction in cane quantity and quality in all Sugarcane growing areas of India including Chhattisgarh also. Considering the importance of the disease an experiment was conducted with sugarcane set treatment with Tebuconazole against whip smut disease through OFT in Kabirdham district of Chhattisgarh during Kharif season 2016-17 and 2017-18 at different location of farmer’s field on variety CO68032 by supervision of Indira Gandhi Krishi Vishwavidyalaya, Krishi Vigyan Kendra, Kabirdham (Chhattisgarh). The sugarcane set was treated with Tebuconazole - 50% @ 0.1% solution for half to one hour before sowing. The experiment was observed by calculation of No. of infested plants/m2, Disease Incidence (%), No of infected shoots and yield data with cost: benefit ratio. Tebuconazole showed good response in all respective parameters with low cost high benefit ratio compare to farmer practices (without any chemical treatment).
