Bio-efficacy of new formulation of carbofuran against major insect pests of rice <em>Oryza sativa</em> L.

Abstract

Bioefficacy of new formulation of carbofuran 3CG were tested in the field condition against stem borer and leaf folder in paddy during kharif 2017 and 2018 at Agricultural Research Station, Gangavathi, and Karnataka. The results confirmed that carbofuran 3CG is an effective chemical in reducing the pest population. Three doses of carbofuran 3CG (750, 1500 and 3000 g.a.i/ha) were tested along with the fipronil 5% SC, carbosulfon 25% EC and cartap hydrochloride 4G. among the treatments carbofuran 3CG @ 3000 g.a.i./ha effectively reduced stem borer (2.25 and 2.41% of white ears) and leaf folder infestation (0.34 and 0.37 larvae/hill) and increased grain yield during both the years as compared to untreated check.
