Abstract
The experiment was conducted in local field conditions of Dera Ghazi Khan during the 2021 Kharif season on three different sites. The core objective of this experiment is to manage Jassid on the cotton crop a major pest. Five different insecticides Dinotefuran, Thiamethoxam, Nitenpyram, Dimethoate and clothianidin were evaluated at recommended doses. The treatments were laid out in randomized complete block designs with three replications. Data regarding the Jassid population before a spray of insecticides and after 24-, 48-, and 72-hour’s of spray were recorded. The reduction in the Jassid population is evaluated by the Abbots formula. The results indicated that Nitenpyram was found most effective on Jassid with mean mortality of 63.47%, 65.07 and 61.86% followed by Dinotefuran with 59.22%, 59.33% and 51.45%. Other treatments thiamethoxam, Dimethoate and clothianidin were at par and did not reduce the Jassid population after 24 and 48 hours. However, thiamethoxam and clothianidin reduced the Jassid population below ETL after 72 hours of spray as compared to Dimethoate. Therefore, it is recommended that Nitenpyram and Dinotefuran should be used for Jassid control at the recommended dose.
