Spread of disease and severity was comparatively lower in treated plots than untreated control. Plants grew more vigorously in imidacloprid followed by thiamethoxam treatments. Seed treatment with imidacloprid proved to be the best. Average number of bolls per plant were 16 in imidacloprid treated plots followed by 12 in thiamethoxam treated plot and 10 in non-treated control. Other yield components were also more in treated plots than untreated control. The yield was estimated to be 80% more in imidacloprid treated plot and 18% in thiamethoxam treated plot over control.]]>Mansoor, S., I. Bedford, M.S. Pinner, J. Stanley and P.G.
