Field evaluation of biointensive module for the management of major insect pests of coleus

Abstract

A field experiment was conducted to evaluate the efficacy of a biointensive module including organic nutrients, botanicals and bio-control agents against major insect pests of coleus (Coleus forskohlii Briq.). The results of the study revealed that biointensive module for coleus (BIMC) II was effective in reducing the incidence of major pest of coleus, recording the mean leaf damage of 5.6 per cent with a reduction of 68.8 per cent for thrips (Scirtothrips dorsalis), 3.4 per cent with a reduction of 63.8 per cent for scale insects (Orthezia insignis) and 7.0 per cent with a reduction of 65.8 per cent over full dose of NPK for defoliator (Orphanostigma abruptalis). Same module recorded the natural enemy activity equal to untreated check and recorded the highest yield of 25,623 kg wet tubers/ha. © JBiopest.
