Abstract

The field experiment undertaken during 2018 at Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar evaluated the efficacy of insecticides by foliar application against fruit fly Bactrocera cucurbitae (Coquillet) in cucumber. Among the treatments evaluated, the least fruit damage at 10 and 14 days after second spray was observed with flubendiamide 480SC @ 0.3 l+ jaggery 5 kg/ ha followed by flubendiamide 480SC @ 0.3 l/ ha. The maximum fruit yield (48.29 q/ ha) was obtained with foliar application of flubendiamide 480SC @ 0.3 l/ ha+ jaggery, and maximum benefit in terms of protection cost benefit ratio (PCBR- 1:12.84) was observed with profenophos 50EC @ 1 l + jaggery 5 kg/ ha.
