- Abstract: 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.
