ABSTRACT
An experiment was conducted at Zonal Agricultural Research Station, V.C farm, Mandya during 2014 and 2015, to assess the chemical control of sugarcane early shoot borer (Chilo infuscatellus). Nine insecticides namely, Fipronil 0.3G, Chlorantraniliprole 0.4G, Chlorantraniliprole 18.5 SC, Spinosad 45SC, Flubendiamide 39.35SC, Cartap hydrochloride 4G, Phorate 10G, Carbofuran 3G, Chlorpyriphos 20EC and compared with untreated (Check plot) using Randomized block design with three replications. Significant differences were noticed among the treatments. The lowest per cent cumulative incidence of early shoot borer and highest percent reduction over control was recorded in Chlorantraniliprole 0.4G followed by Chlorantraniliprole 18.5 SC, Cartap hydrochloride 4G, Flubendiamide 39.35SC, Fipronil 0.3G and Spinosad 45SC. Further the highest cane yield was recorded in, Chlorantraniliprole 0.4G followed by Fipronil 0.3G, Chlorantraniliprole 18.5 SC, Flubendiamide 39.35SC, Cartap hydrochloride 4G and Spinosad 45SC. Among the insecticides, Fipronil 0.3G proved to be superior with highest B:C ratio followed by Cartap hydrochloride 4G and Chlorantraniliprole 0.4G.
