Abstract
The efficacy of phosmet was evaluated against the aerial form of the woolly apple aphid Eriosoma lanigerum (Hausmann) during October- November 2017 and 2019 in apple orchards at Manali district Kullu of Himachal Pradesh. All the doses of phosmet were effective in suppression of the aphid up to 21 days of the spray. Chlorpyriphos (0.05%) was found statistically superior (0.06 aphid colonies/twig) followed by phosmet @ 0.075%, 0.05% and 0.025% (0.36, 0.40 and 0.54 aphid colonies/twig, respectively) during 2017. Similar trend was observed during 2019 but chlorpyriphos was found statistically at par with phosmet @ 0.05% and 0.075%. All the concentrations proved safe to the apple plants as there were no phytotoxic symptoms.
