ABSTRACT

An evaluation of the efficacy of many novel pesticides against important sucking pests on cotton in field situation was carried out in 2023 at the Cotton Research Station, Ayub Agriculture Research Institute (ARRI), Faisalabad. A number of the most notorious and destructive pests to cotton crops are sucking insects, including whitefly Bemisia tabaci, jassid, Amrasca biguttula and thrips, Thrips tabaci. About 28% of losses occur in cotton crops every year due to the attack of these insect pests. The major goal of chemical control, which includes using different pesticides is to reduce yield losses in cotton crops. In order to identify an insecticide that could efficiently manage these sucking insect pests of cotton, the toxicity a few selected insecticides in the field have been assessed in current study. Six insecticides, when used alone or in a combination viz. chlothianidin 200ml/acre, spirotetramate 250ml/acre, matrine 500ml/acre, flunicamid 80gm/acre, imidacloprid + acephate 500gm/acre and dinotefuran 100gm/acre were tested against sucking insect pests such as whiteflies, jassids and thrips on cotton under field conditions at AARI Faisalabad. The population of cotton sucking insect pests was counted prior to pesticide administration as well as on 1st, 3rd, and 7th days following pesticide application. The results of this study revealed that overall reduction percentage of flunicamid and dinotefuran after 1st, 3rd, and 7th days was 33.33, 46.79, and 71.15%, and 30.52, 44.16, and 69.48%, respectively against jassid after first spray and second spray. The overall reduction percentage of whitefly flunicamid after 1st, 3rd, and 7th days was 22.20, 44.54, and 73.39%, respectively after first spray. the first spray against thrips, the mixture of Imidacloprid and Acephate reduced the maximum insect infestation from 16.33 to 6.79 per leaf, respectively. The overall reduction percent of Imidacloprid + Acephate after 1st, 3rd, and 7th days was 10.89, 9.78, and 6.79%, respectively. All tested insecticides caused a significant reduction in jassid, whitefly, and thrips even after first and second spray.
