Abstract

Investigations were carried out to assess the efficacy of neonicotinoids by application on the auxillary and main stem of coffee plants. The results showed that stem application of thiamethoxam at 0.05 g.a.i./plant in the auxillary branches was very effective in suppressing the population of Coccus viridis causing 93.1 % reduction. Application of insecticides over the main stem was not that much effective. Thiamethoxam at 0.025 g.a.i./plant was comparable with imidacloprid (0.05 g.a.i.) and dimethoate (0.3 g.a.i.) applied.
