Efficacy of different insecticides against aphid on brassica juncea

Abstract

A field experiment was conducted to find out and compare the efficacy of Pyriproxyfen, Nitenpyram, Carbosulfan and Chlorpyrifos against aphid on Brassica juncea variety (Bahawalpur Raya) during Rabi 2016-17 at Regional Agricultural Research Institute, Bahawalpur, Pakistan. After 72 hours of treatment carbosulfan, nitenpyram and pyriproxyfen showed statistically similar results. Aphid population reduction of 96.7% was observed on the brassica plants treated with Carbosulfan, followed by 96.4% and 91.6% control of aphid infestation caused by Nitenpyram and Pryriproxyfen respectively. Chlorpyrifos showed 67.8% results.
