| Abstract | ||||
| Five common insecticides (imidacloprid, emamectin benzoate, abamectin, thiamethoxam and Lambada-cyhalothrin), their mixtures with mancozeb and certain non- synthetic agrochemicals (Hydrogen Peroxide 35%, Calcium aluminum sulphate (Alum), Palm oil, lime sulphur and mixture from lime sulphur + Boric acid were evaluated to control Aphids in Egg plants under field conditions. Their selectivity against Coccinella undeciumpunctata were also studied during 2023 season. The results showed that insecticide and non- synthetic agrochemicals were highly effective in controlling Aphis gossypii, Also, the mancozeb gave an additive effect for all tested insecticide. Insecticide and non- synthetic agrochemicals were highly safe on C. undeciumpunctata except lambda-cyhalothrin. Average maximum reduction (%) of A. gossypii were achieved by imidacloprid (80.9%) followed by acetamiprid and lambada-cyhalothrin (73.7 and 73.7%) followed by abamectin (72.6%) and the last one was emamectin benzoate by (68.7%), respectively in 2023 seasons. | ||||
