Field experiment was conducted to evaluate the efficacy of some new insecticides against sucking insect pest’s viz., leafhopper, aphid, Thrips and whitefly in okra. Two sprays of different insecticides viz., BAS 450 01 I 300 SC, Chlorantraniliprole 18.5% SC, Cypermethrin 10% EC, at three different concentrations of BAS 450 01 I 300 SC@ 18.5, 12.5 and 6.5 g.a.i./ha were made at 1,3,5,7 and 10 days interval. All the treatments registered significantly lower population of sucking pests as compared to untreated control. BAS 450 01 I 300 [email protected] g.a.i./ha proved the best treatment for the control of the sucking pest, however, treatments viz., BAS 450 01 I 300 SC@ 12.5 g.a.i./h and Chlorantraniliprole 18.5% SC @ 25 g.a.i./ha were also observed to be effective treatments in most of the observations.
