Abstract
The green apple aphid, Aphis pomi De
Geer (Hemiptera: Aphididae), is a major pest affecting apple
cultivation, causing significant yield losses. Neonicotinoids, particularly
imidacloprid, are commonly used worldwide for aphid control. This study
evaluated the field efficacy of various concentrations of imidacloprid 17.8% SL
against A. pomi under open-field conditions in Kashmir. All tested
concentrations significantly suppressed aphid populations compared to the
standard check (Chlorpyrifos 20EC) and the untreated control. The highest
reductions were observed at 0.5 and 0.6 ml/L concentrations of imidacloprid,
achieving 93.65% and 95.99% control in the first year, and 90.71% and 93.24% in
the second year, respectively, at 21 days post-application. In contrast,
Chlorpyrifos 20EC showed only 5.63% reduction, indicating markedly lower
efficacy. These results confirm that imidacloprid 17.8% SL is highly effective
against A. pomi and should be considered a reliable component of
integrated pest management (IPM) strategies for apple orchards in Kashmir and
other temperate apple-growing regions of India.
