The present study on evaluation of insecticides for the management of brown plant hopper and white backed plant hopper in rice crop was undertaken at Agriculture Research Station, Sakoli, Bhandara district during kharif 2021. The experimental plot was laid out in Randomized Block Design (RBD) incorporating seventeen treatments along with control consisting of seed treatment of Thiamethoxam 25 % WG, nursery application at one week before of Carbofuran 3% CG, Fipronil 0.3 % GR, Chlorantraniliprole 0.4 % GR, main field application at 22 DAT of Carbofuran 3 % CG, Fipronil 0.3% GR, Chlorantraniliprole 0.4% GR, Cartap hydrochloride 4 % GR, Chlorpyrifos 10% GR, Thiamethoxam 25% WG (seed treatment) + Fipronil 0.3 % GR (main field), Thiamethoxam 25% WG (seed treatment) + Chlorantraniliprole 0.4 % GR (main field), Thiamethoxam 25% WG (seed treatment) + Cartap hydrochloride 4 % GR (main field), Thiamethoxam 25% WG (seed treatment) + Chlorpyrifos 10 % GR (main field), Fipronil 0.3% GR (nursery) + Chlorantraniliprole 0.4 GR % (main field), Fipronil 0.3% GR (nursery) + Cartap hydrochloride 4 % GR (main field), Fipronil 0.3 % GR (nursery) + Chlorpyrifos 10 % GR (main field). The results clearly revealed that Chlorantraniliprole 0.4% GR (main field) was most promising in controlling brown plant hopper and at par with treatment Carbofuran 3% CG (nursery), Chlorpyrifos 10% GR (main field), Chlorantraniliprole 0.4% GR (main field) and Carbofuran 3% CG (nursery) was most promising in controlling white backed plant hopper and at par with Chlorantraniliprole 0.4% GR (nursery), Chlorpyrifos 10% GR (main field), Chlorantraniliprole 0.4% GR (main field). Highest yield was noticed in Chlorantraniliprole (main field) (44.33 q/ha) followed by Fipronil 0.3% GR (nursery) + Chlorantraniliprole 0.4% GR (main field) (38.59 q/ha) and Chlorpyrifos 10% GR (main field) (38.22 q/ha). ICBR is highest for Carbofuran 3% CG (nursery) followed by Chlorantraniliprole 0.4% GR (nursery), Fipronil 0.3% GR (nursery), Chlorpyrifos 10% GR (main field) and Thiamethoxam 25% WG (seed treatment).

Brown plant hopper, White backed plant hopper, Capsulated granules

The brown plant hopper was found to be the serious pest of paddy. Similarly, low incidence of white backed plant hopper was recorded. From the data it can be concluded that Chlorantraniliprole 0.4 % GR (Main Field) was effective in management of brown plant hopper and Carbofuran 3% CG (nursery) was effective in management of white backed plant hopper. Highest grain yield was recorded in plot treated with Chlorantraniliprole 0.4 % GR (Main Field) followed by Fipronil 0.3% GR (nursery) + Chlorantraniliprole 0.4% GR (main field), Chlorpyrifos 10% GR (main field), Fipronil 0.3% GR (nursery) + Chlorpyrifos 10% GR (main field), Thiamethoxam 25% WG (seed treatment) + Chlorpyrifos 10% GR (main field). Among different treatments, incremental cost benefit ratio in Carbofuran 3% CG (Nursery) was found highest followed by Chlorantraniliprole 0.4% GR (nursery), Fipronil 0.3% GR (nursery), Chlorpyrifos 10% GR (main field). Thus, the above insecticides are the better option to manage the brown plant hopper and white backed plant hopper of paddy.
