摘要

Studies on the efficacy of five different insecticide i.e. Thiodan 35 EC (Endosulfan), Actara 25 WG (Thiamethoxam), Match 050 EC (Lufenuron), Supracide 40 EC (Methiodethion) and Laser 25 EC (Dimethoate+Cypermethrin) were carried out against citrus leaf miner ( Phyllocnistis citrella stnt) in April, 2002 at Agricultural Research Institute (ARI) Tarnab, Peshawar. The results revealed that after first application, Thiodan 35 EC proved to be the best insecticide followed by Actara 25 WG, Match 050 EC, Supracide 40 EC and Laser 25 EC with infestation of 2.70, 4.41, 5.67, 6.93 and 9.62% of leaf miner per 6" tender shoot, respectively. Wherein control, it was 19.84%. Similarly, after second spray the minimum percent infestation was recorded in Thiodan 35 EC followed by Actara 25 WG, Match 050 EC, Supracide 40 EC and Laser 25 EC as 2.41, 3.84, 5.15, 6.16 and 7.74%, respectively. Where in check it was recorded as 13.38%. Based on the present finding it could be suggested that Actara 25 WG and Thiodan 35 EC should be listed in the spray schedule for the control of citrus leaf miner.
