Study on different insecticide application methods against white grub, H. consanguinea.

Abstract

A field experiment comprised of two insecticides with four different application methods tested against white grub on groundnut was conducted in endemic area of Junagadh District at Oil Seed Research Station, Manavadar. Different methods of insecticides application (Seed treatment, Drenching, Chemigation and Broadcasting) in groundnut against the white grub, seed treatment of clothianidin 50% WDG (ST) @ 250 gm per ha and chlorpyriphos 20% EC (ST) @ 4000 ml per ha were found most effective treatments against white grub in groundnut and maximum yield can be found. Although, seed treatment with clothianidin 50% WDG (ST) @ 250 gm per ha was the most profitable treatment (NICBR = 1:2.42).
