FIELD EVALUATION OF BIOINTENSIVE MODULE FOR THE MANAGEMENT OF MAJOR INSECT PESTS OF COLEUS

A fieldexperiment was conducted to evaluate the efficacy of a biointensive moduleincluding organic nutrients, botanicals and bio-control agents against majorinsect pests of coleus (Coleus forskohlii Briq.). The results of thestudy revealed that biointensive module for coleus (BIMC) II was effective inreducing the incidence of major pest of coleus, recording the mean leaf damageof 5.6 per cent with a reduction of 68.8 per cent for thrips (Scirtothripsdorsalis), 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 centover full dose of NPK for defoliator (Orphanostigma abruptalis). Same modulerecorded the natural enemy activity equal to untreated check and recorded thehighest yield of 25,623 kg wet tubers/ha.
