S.D. Mohapatra, P N Mishra, MP Singh

Abstract

White grubs are a major production constraint in upland rice production in North-Western Himalayas. Field experiment was carried out to evaluate five insecticides viz., chlorpyriphos 20 EC, quinalphos 25 EC, lindane 20 EC, imidacloprid 200 SL and lamda cyhalothrin 5 EC as post-sown soil application in furrows against the white grub, Holotrichia longipennis Blanch damaging upland rice in Uttarakhand hills. Imidacloprid 200 SL @ 80.0 g a.i. ha−1 was found to be most effective by registering lowest cumulative plant mortality (3.14%) and grub populations (2.0 grubs pit−1). Highest benefit cost ratio (6.72) was obtained in the treatment of imidacloprid 200 SL (60g a.i. ha−1).
