Of the seven insecticides evaluated against S. litura, the treatment of chlorantraniliprole 10 + lambda-cyhalothrin 5 ZC @ 0.006% recorded the lowest (1.06) larvae/plant, which was statistically at par with novaluron 5.25 + emamectin benzoate 0.9 SC @ 0.009% (1.25 larvae/plant) and novaluron 5.25 + indoxacarb 4.5 SC @ 0.016% (1.38 larvae/plant) after 3 days of the first spray. A similar trend was seen after 7 and 10 days of the first spray as well as 3, 7, and 10 days after the second spray. The highest (2640 kg/ha) yield of soybean was produced in the treatment of chlorantraniliprole 10 + lambda-cyhalothrin 5 ZC 0.006% followed by novaluron 5.25 + emamectin benzoate 0.9 SC 0.009% (2346 kg/ha) and novaluron 5.25 + indoxacarb 4.5 SC 0.016% (2268 kg/ha). Looking to the ICBR, the treatment of chlorantraniliprole 10 + lambda-cyhalothrin 5 ZC 0.006% noted the highest (1:8.8) ICBR followed by thiamethoxam 12.6 + lambda-cyhalothrin 9.5 ZC 0.011% (1:8.3) and chlorpyriphos 50 + cypermethrin 5 EC 0.11% (1:7.1). 10 31 2024 383 390 1 10.31254/biomed-crossmark-policy www.biomedresearch.org false 10.31254/phyto.2024.13507 https://www.phytopharmajournal.com/assets/pdf_files/Vol13_Issue5_07.pdf
