Abstract

Cotton, the white gold, is an important fiber crop that is grown as a commercial crop all over the world. Among the several factors contributing to the low yield of cotton, biotic constraints appear to be very important that are ravages caused by insect pests assume greater importance. Sucking the cell sap caused by whitefly gives a great reaction, which transfers viral diseases to the cotton after secreting the honeydew. For this, a trial was conducted Ayub Agricultural Research Institute (AARI) and a local farmer’s field during 2023-2024 cotton season to check the efficacy of different insecticides against the critical cotton insect pest, whitefly (Bemisia tabaci). In this study, Dufire 70% WDG, Crunch Super 75% WDG, Ulala 50%, Oshin 20% SG, and neem oil were applied in the cotton field and the data of the whitefly population were recorded the day after application, 72 hrs., and 7 days after application of insecticides. The data was taken accordingly, and it was seen that each insecticide significantly reduced the population to a certain level, but Oshin and Ulala proved to be the best chemicals to decrease the whitefly population in field conditions. The population of whitefly in treated areas of Ayub Agricultural Research Institute was always maximum in control conditions after the pesticides were applied and the least value was observed in neem oil and control-treated plots.
