The dissipation of spirodiclofen in fresh fruit and dry fruit of wolfberry was detected in this study to provide a reference for its safe application.According to Pesticide Residue Test Criteria of China, the open-field experiment was conducted in Zhongning courty of Ningxia province, and the dissipation of spirodiclofen was studied by acetonitrile extraction and HPLC-MS/MS detection. The results showed that the half-lives of spirodiclofen in fresh wolfberry fruit and dry wolfberry fruit were 6.9-11.2 days and 8.5-10.4 days, respectively. Spirodiclofen belongs to the easily degradable pesticide type. According to the maximum residue limits (0.5 mg•kg⁻¹) of spirodiclofen of EU for wolfberry, after recommended dosage being sprayed for once, fresh wolfberry fruit was safe to eat after 5 days, and dry wolfberry fruit was safe to eat after 21 days.
本研究检测了螺螨酯在枸杞鲜果和干果中的消解情况，为其安全使用提供参考。按照我国农药残留试验准则，在宁夏中宁县进行田间试验，采用乙腈萃取和高效液相色谱 - 串联质谱检测法研究螺螨酯的消解情况。结果表明，螺螨酯在枸杞鲜果和干果中的半衰期分别为6.9 - 11.2天和8.5 - 10.4天。螺螨酯属于易降解农药类型。根据欧盟对枸杞中螺螨酯的最大残留限量（0.5 mg•kg⁻¹），按推荐剂量喷施一次后，枸杞鲜果5天后食用安全，枸杞干果21天后食用安全。
