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 based on the final residue levels and acceptable daily intakes. The hazard quotient values for the pesticides tested ranged from 1.07 to 64.94%.
