Combi-product of β-Cyfluthrin + Imidacloprid (Solomon 300 OD) for Managing Sucking Insect Pests in Bt Cotton

The study was conducted to assess the bioefficacy of new combi-product of β-cyfluthrin 9% + imidacloprid 21% (Solomon 300 OD) @ 150, 175 and 200 mL ha⁻¹ (13.5 + 31.5, 15.75 + 36.75 and 18 + 42 g ai ha⁻¹) along with imidacloprid (Confidor 200 SL) @ 125 mL and 210 mL ha⁻¹ (25 and 42 g ai ha⁻¹) and diafenthiuron (Polo 50 WP) @ 500 g ha⁻¹ (250 g ai ha⁻¹) as standards check against whitefly and leafhopper, respectively, on Bt cotton during 2017 and 2018 crop season, Maximum reduction in whitefly (64.8 and 73.5%) and leafhopper (78.6 and 84.9%) was recorded in Solomon 300 OD @ 175 and 200 mL ha⁻¹, respectively. Solomon 300 OD @ 200 mL ha⁻¹ recorded higher seed cotton yield (23.71 q ha⁻¹) and was at par with the diafenthiuron @ 500 g ha⁻¹ (23.45q ha⁻¹) and Solomon 300 OD @ 175 mL ha⁻¹ (22.78 q ha⁻¹) without causing any phytotoxicity to Bt cotton.
