Abstract

This study evaluated the efficacy of flonicamid 50%WG (50, 75 and 100 g ai ha-1) along with imidacloprid 17.8SL (25 g ai ha-1), thiamethoxam 25%WG (25 g ai ha-1), chlorpyriphos 19%ME (180 g ai ha-1) and fipronil 5% SC (75 g ai ha-1) against the rice ear head bug Leptocorisa acuta (Thunberg) in rice. The results revealed that flonicamid @ 100 g ai/ ha was the most effective (1.0 bugs hill-1) followed by flonicamid @ 75 g (1.13 bugs hill-1). Imidacloprid (1.22 bugs hill-1) was statistically on par with that of flonicamid @ 50 g (1.23 bugs hill-1) and thiamethoxam (1.24 bugs hill-1). The yield and cost-effectiveness were maximum in the flonicamid (48.93 q ha-1 @ 100 g) and imidacloprid (B: C; 2.43:1).
