Field and lab experiments explored tetraniliprole dissipation in chili plants. A supervised trial in Devarayapuram village, Coimbatore, assessed the CO 2 chili variety (December-March 2018-2019). Using the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method and ultra-high-performance liquid chromatography (UHPLC), samples were collected up to 15 d post-application. Initial tetraniliprole deposits on chili fruits, 1-h post-spray, were 0.898 and 1.271 μg g -1 at single and double doses. Over 80% dissipated within 5 d, reaching below detection limits by day 7 and 10 for single and double doses, respectively. Transformation analysis favored first-order kinetics. Tetraniliprole half-life on chili fruit was 1.49 and 1.53 d at recommended and double doses. The safe waiting period was 4.16 and 5.04 d for 60 and 120 g a.i ha -1 . This study provides insights into tetraniliprole dynamics in chili plants, crucial for effective pesticide management.
