Compliance with application instructions and safety precautions significantly reduces pesticide residues that may have adverse effects. Field trials were thus carried out to determine the degradation of Agromec® 1.8% EC (abamectin 1.8% (w/v)) and Shooter® 30% SC (pyraclostrobin 20% + boscalid 10% (w/w)) in/on apple fruits. Before starting Field trials, the tested pesticide formulations were subjected to analysis before and after accelerated storage at 54 ±2 oC for 14 days; the active ingredient content, emulsion stability, and suspensibility were found to comply with the chemical and physical specifications. The pesticides were applied to the treated apple trees using a knapsack sprayer at the recommended rates. The QuEChERS method was used for sample extraction and cleaning. HPLC-UV was used to determine residue amounts up to 15 days after application. The mean recovery percentages for abamectin, pyraclostrobin, and boscalid were 82.27, 88, and 101%, respectively. Furthermore, the methods' coefficient variation obtained was 1.71- 2.48%. At the same time, the LOQ values for abamectin, pyraclostrobin, and boscalid were 0.1, 0.25, and 0.25 mg/kg, respectively. Abamectin, pyraclostrobin, and boscalid initial deposits on/in apple were 0.955, 2.24, and 3.66 mg/kg, respectively. The degradation rate constants were 0.803, 0.14, and 0.21, respectively, with corresponding half-life times of 0.86, 4.95, and 3.3 days and pre-harvest intervals of 4.32, 10.71, and 2.88 days for abamectin, pyraclostrobin, and boscalid. The potential health risks associated with exposure to the chemicals under investigation were calculated
