Bio-efficacy of BAS 450 01 I 300 SC against major insect pests of okra during Kharif season 2015-16 to 2016-17

Abstract

An experiment was conducted to observe the “Bio-efficacy of BAS 450 01 I 300 SC against major insect pests of okra during Kharif Season2015-16 and 2016-17” at Horticulture farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya (IGKV), Raipur, Chhattisgarh. In okra crop, novel approaches of insect management by using new molecules of insecticides may play important role to manage shoot and fruit borer and safer to non target pest and natural enemies. Two year computed data of mean per cent of fruit damage indicated that, the plot 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.
