Efficacy of Combi-Product Fipronil 40%+ Imidacloprid 40%WG Against Leafhopper and Thrips in Cotton

The efficacy of lessenta 80 WG (fipronil 40%+ imidacloprid 40%WG) @ 125, 100 and 75 g ai/ ha was evaluated against sucking pests of cotton in comparison with the fipronil 5%SC @ 125 g ai/ ha, imidacloprid 17.8 SL @ 250 g ai/ ha, lambda-cyhalothrin 5%EC @ 600 g ai/ ha and monocrotophos 36%SL @ 437 g ai/ ha at the Agricultural Research Station, Dharwad, Karnataka, India. Fipronil 40%+ imidacloprid 40%WG @ 125 g ai/ ha recorded significantly minimum (8.25 and 3.01) Thrips tabaci (Lindeman) (Thysanoptera: Thripidae) and Amrasca biguttula biguttula (Ishida) (Hemiptera: Cicadellidae) incidence, respectively followed by lessenta 80 WG @ 100 g ai/ ha (8.68 and 3.42, respectivey) and fipronil 40%+ imidacloprid 40%WG @ 75 g ai/ ha (9.55 and 3.98, respectively). Further, significantly highest seed cotton yield of 13.99 q/ha, 13.58 q/ha and 12.86 q/ha, respectively were harvested from the fipronil 40%+ imidacloprid 40%WG treatments proving them better choice in effective management of both A. biguttula biguttula and T. tabaci incidence.
