Management of the white grub Holotrichia consanguinea infesting groundnut by chemical insecticides

The present experiment that conducted during kharif 2023 at Rainfed agriculture research farm, Department of Entomology, Bundelkhand University Jhansi was worked out with nine treatments and three replications under randomized block design, where two time chemical insecticides were applied by soil drenching method in groundnut crop field against White grub Holotrichia consanguinea infestation and data were collected before and after every application of treatment that resulted Imidacloprid 17.8% SL was found best effective among all treatments to control the plant mortality of the groundnut crop followed by Chlorantraniliprole 18.5% EC and Chloropyriphos20%EC, and maximum yield and C:B ratio, 18.69 Qt/hac pod yield and 1:1.61 was obtained under Imidacloprid 17.8% SL treated plot followed by the Chlorantraniliprole 18.5% EC and Chloropyriphos20%EC that were produced 17.89 Qt/hac and 16.25qt/hac pod yield respectively, and remain all treatments were significantly effective over control (untreated plot).
