“…In most eld situations, control of soil pests is very di cult because of the limited effectiveness of control measures. Various insecticides have been reported for the management of white grub from different parts of India (Thirumurugan et al, 2020). However, very little information exists on the e cacy of these insecticides against white grubs in the Nainital district of the Kumaon region of Uttarakhand.…”

The experiment was carried out to study the efficacy of various insecticides viz., Carbofuran 3G @ 750g a.i./ha, Clothianidin 50WDG @ 120g a.i./ha, Fipronil 0.3G @ 50g a.i./ha, Thiamethoxam 25WG @ 80g a.i./ha, Imidacloprid 70WG @ 300g a.i./ha, Chlorantraniliprole 0.4 GR @100g a.i./ha, Fipronil 40% + Imidacloprid 40% WG @ 300g a.i./ha Chlorpyrifos 10G @ 300g a.i./ha and Emamectin benzoate 5SG @ 12.5g a.i./ha against white grubs infesting soybean crops. All treatments were shown to be significantly superior to the control. During the 2019 and 2020 cropping seasons, Fipronil 40% + Imidacloprid 40% WG @ 300g a.i./ha was shown to be the most effective in terms of percent decrease over the control, i.e., 81.95 and 79.31%, respectively, followed by Clothianidin 50WDG @ 120g a.i./ha (78.95 and 77.46%). Emamectin benzoate 5SG at 12.5g a.i./ha was found to be less effective, reducing plant damage by 30.07% during the previous year and 39.37% during the next years. The maximum soybean yield and cost benefit ratio was obtained from the plot treated with Fipronil 40% + Imidacloprid 40% WG @ 300g a.i./ha, while the lowest was obtained from the plot treated with Emamectin benzoate 5SG @ 12.5g a.i./ha. Observations recorded on the following application of insecticides revealed that there was no evidence of phytotoxicity in any of the treated soybean plots. Experimental results demonstrated that Fipronil 40% + Imidacloprid 40% WG applied at 300g a.i./ha was effective for the control of white grub in soybean crop without harming natural enemies.
