A Study On Bio Efficacy Of Cyantraniliprole 10.6% OD Against Major Sucking Pests Of Watermelon

Abstract

Cyantraniliprole, 10.6% OD, was evaluated in the field against major sucking pests of watermelon at Jaguli Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya (BCKV) during 2020-21. The study took place during the kharif season, and the watermelon variety named ‘Krishna’ was selected and grown with proper agronomic practices. A total of three sprays were done starting from the ETL of the pest population. The spraying was done at ten days intervals with four different doses of Cyantraniliprole, 10.6% OD along with Imidacloprid 17.8% SL @ 100 g a.i./ha, Spinosad 45% SC @ 73 g a.i./ha (standard checks) and an untreated control. All the treatment is arranged in randomized block design with three replications, each consisting of seven treatments. The results revealed that treatments cyantraniliprole 10.6% OD @ 120 g a.i/ha and 90 g a.i/ha were substantially more potent with regard to its efficacy on the basis of three sprays, compared to untreated control.
