Studies were conducted to observe the physico-morphic influence of different doses of Tamaron 600 SL viz., 200, 300, 400, 500 and 600 ml per acre on FH-682 cotton at Faisalabad under natural field conditions. The experiment was laid out in Randomized Complete Block Design with 6 treatments including control and with 3 repeats. The crop was sprayed 3 times during its growth season. All the physico-morphic characters were studied at crop maturity stage. Results revealed that Tamaron 600 SL @ 400 ml/acre was found to be the most effective than others. Seed cotton yield was found to be positively correlated only to the plant height, weight of dry brackets and number of opened bolls but other plant characters like weight of dry leaves, weight of dry stem, number of leaves, number of unopened bolls and leaf area index were found to be negatively correlated. All the characters under study showed significant differences to different doses of insecticide under trial. |

seasons. All the physico-morphic characters were studied at crop maturity
stage. Results revealed that Tamaron 600 SL @ 400 ml acre-1
was found to be most effective than others. Seed cotton yield was found
to be positively correlated only to the plant height of dry brackets and
number of opened bolls but other plant characters like weight of dry leaves,
weight of dry stem, number of leaves, number of unopened bolls and leaf
area index were found to be negatively correlated. All the characters

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. |
