Investigations on the toxic effect of different doses of Dimecron 100 SCW (phosphamidon) on cotton variety FH-682 on thrips Thrips tabaci Lind. were carried out under natural field conditions at Faisalabad. Different doses of Dimecron 100 SCW (phosphamidon) under trial were 150, 200, 250, 300 and 400 ml/acre. Trials were laid-out in Randomized Complete Block Design having six treatments including control having five repeats each. The spray material was prepared on vol./vol. basis and sprayed on the crop by using Solo-Knapsack Sprayer at fortnight interval. The data were recorded early in the morning 24, 48, 72 hours and 7 days after each spray. Data were recorded from 20 randomly selected plants from upper middle and lower portion on per leaf basis. Crop was sprayed 3 times during the growth period. The efficacy of different doses was considered to be an indirect reflection of thrips population. Dose of 400 ml was found to be the most effective followed by all other dosages in descending order.
