abstract
A field experiment was conducted during 2017-18 at Pantnagar (India) to evaluate the bio-efficacy of Solomon 300 OD (beta-cyfluthrin 9% + imidacloprid 21%) against wheat aphid in comparison to beta-cyfluthrin 25 SC, imidacloprid 200 SL, quinalphos 25 EC and thiamethoxam 25 WG. The treatment of Solomon 300 OD @ 400 ml/ha was found to be the most superior in reducing aphid population with higher grain yield of wheat. At this concentration, it did not show any symptom of phytotoxicity on wheat.
