Abstract
The woolly aphid, Eriosoma lanigerum (Hausmann) (Aphididae: Homoptera) on apple, a key pest was studied in its aerial form for field efficacy of five insecticides namely spirotetramat (Movento150OD)0.009, 0.012, 0.015%, flupyradifurone (Sivanto 200SL)-0.02, 0.03, 0.04%, thiamethoxam (Thomson 25WG)-0.012, 0.025% and flonicamid (Ulala 50WG)-0.20, 0.30, 0.40%. These were compared with chlorpyriphos (Dursban 20 EC) 0.04%. The field trial was conducted during October-November of 2015 in apple orchards at Regional Horticulture Research and Training Station, Mashobra. The results revealed that all the treatments were superior, and 21 days after spray, chlorpyriphos (0.04%) and thiamethoxam 25WG (0.025%) were the best with zero infestation; but these were statistically at par with flupyradifurone (0.03 and 0.04%. Spirotetramat was observed to be the least effective. All the insecticides proved safe as regards phytotoxic symptoms.
