Residue distribution of fluopyram and tebuconazole was assessed in pomegranate whole fruit, aril, outer peel (pericarp), inner peel (mesocarp) and leaves. The method LOQ of fluopyram and tebuconazole were 0.01 and 0.02 mg kg, respectively. Both fungicides remained in fruit peel and residues in edible aril were < LOQ. In fruit peel major portion of the fungicides remained on pericarp with minimal movement to mesocarp. In mesocarp fluopyram was 5.7-14.2%; tebuconazole, 7.5-14.4% of the residues in pericarp. Terminal residues of fluopyram and tebuconazole in pomegranate whole fruit were 0.037-0.094 and 0.036-0.096 mg kg. Half-life of fluopyram in pomegranate fruit and leaves were 7.3-9.1 and 15 days; tebuconazole, 8-10.3 and 11.2-12.6 days, respectively. Pre-harvest intervals for treatment of combination formulation of fluopyram and tebuconazole, were 47-59 days in fruits, 158-173 in leaves. Dietary risk assessment demonstrated that consumption of peel and leaves may pose risk to human health, whereas fruit consumption was considered safe.
氟吡菌酰胺和戊唑醇在石榴整个果实、果肉、外果皮（果皮）、中果皮（中果皮）和叶片中的残留分布情况进行了评估。氟吡菌酰胺和戊唑醇的方法检出限（LOQ）分别为 0.01 和 0.02mg/kg。两种杀菌剂均残留在果皮中，可食用果肉中的残留量均低于 LOQ。在果皮中，大部分杀菌剂残留在果皮上，向中果皮移动的量最小。在中果皮中，氟吡菌酰胺为 5.7-14.2%；戊唑醇为 7.5-14.4%的果皮残留。石榴全果中氟吡菌酰胺和戊唑醇的最终残留量为 0.037-0.094 和 0.036-0.096mg/kg。氟吡菌酰胺和戊唑醇在石榴果实和叶片中的半衰期分别为 7.3-9.1 和 15 天；8-10.3 和 11.2-12.6 天。氟吡菌酰胺和戊唑醇复配制剂处理的石榴收获前间隔分别为 47-59 天和 158-173 天。膳食风险评估表明，食用果皮和叶片可能对人体健康构成风险，而食用水果则被认为是安全的。
