abstract
The studies were conducted to determine the efficacy of four insecticides, imidacloprid (Confidor 200 SL) @ 150 ml/acre, acetamiprid (Mospilan 20 SP) @ 80g/acre, carbosulfan (Advantage 20 EC) @ 300 ml/acre and thiamethoxam (Actara 25 WP) @ 24g/acre with different mode of actions were tested against mustard aphid (Lipaphis erysimi Kalt.) in the field of canola crop at Entomological Research Area of University of Agriculture Faisalabad during 2013-14. The data was recorded pre and post (24 hrs, 48 hrs, 72 hrs and 1 week) treatment. Results showed that all the four insecticides, viz., imidacloprid (Confidor 200 SL) @ 150 ml/acre, acetamiprid (Mospilan 20 SP) @ 80 g/acre, carbosulfan (Advantage 20 EC) @ 300 ml/acre and thiamethoxam (Actara 25 WP) @ 24 g/acre, Advantage 20 EC (carbosulfan) @ 300 ml/acre gave satisfactory results as compared with control. But statistically highest population reduction was found with the application of Advantage 20 EC (carbosulfan) @ 300 ml/acre while the lowest population reduction was found with Mospilan 20 SP (acetamiprid) @ 80 g/acre. It is concluded that all insecticides were effective statistically against the Lipaphis erysimi (Kalt.) need to be tested on different cultivars of rapeseed mustard.
