Abstract
This study aimed to assess the effectiveness of chemical insecticides against canola aphids during the winter of 2019 at The University of Agriculture Peshawar. Treatments including Cypermethrin @ 3ml/lit, Indoxacarb @ 0.5 ml/lit, Bifenthrin @ 2.5 ml/lit, lambda‐cyhalothrin @ 1.5‐2 ml/lit and a control (tap water) were applied four times monthly at 7‐day intervals. Aphid population data were recorded, with the highest infestation (3.1 Aphids leaf‐1) observed during the 2nd week of November. Results indicated that lambda‐cyhalothrin resulted in the lowest mean infestation (3.74±0.36), followed by bifenthrin (3.95±0.32), indoxacarb (4.35±0.28) and cypermethrin (4.55±0.28). Furthermore, the maximum yield (16.00±0.49 ha‐1) was obtained from lambda‐ cyhalothrin‐treated plots, while the minimum yield (7.17±0.43 ha‐1) was recorded in the control group. The highest mortality rate of 100% was achieved by lambda‐cyhalothrin and cypermethrin after 72 hours of testing. Based on these findings, further investigations into the potential side effects of synthetic insecticides are recommended to better understand their impact on the ecosystem.
