Abstract
A field study was conducted in Loralai during spring 2023 evaluated the efficacy of botanical insecticides against leaf miner infestations in squash. Using a Randomized Complete Block Design (RCBD) with five treatments (Neem oil 5%, Tobacco extract 2%, Chili extract 5%, Chinaberry extract 10%, and along with control), each treatment with replicated three times, the experiment assessed infestation levels over five weeks. Chinaberry extract proved the most effective, reducing mean leaf miner populations to (7.43), followed by Tobacco extract (12.42), Chili extract (13.36), and Neem oil extract (13.88). The control had the highest infestation rate (27.23). It is concluded from the study that all the botanical extracts showed best results against squash leaf miner, but botanical extract of Chinaberry extract superior efficacy against squash leaf miners. It is recommended that botanical extract of Chinaberry is batter control against leaf miner.
