Abstract:

To clarify the residues and dietary risks of several pesticides commonly used for the control of Apolygus lucorum in grapes, studies were carried out on three common pesticides: emamectinbenzoate, thiamethoxam and acetamiprid. The results showed that the degradation of these three pesticides in grape were in accordance with the first-order kinetic equation, and could degrade to below the maximum residue level (MRL) value after 14 days. Three kinds of pesticide residues in degradation of 14 days dietary risk assessment results showed that the three kinds of pesticide risk of chronic and acute risk and total dietary risk was less than 100%, which indicated that according to the recommended use method, the dietary risk of these three test pesticides was low after 14 days, and could be recommended for control Apolygus lucorum and the recommended security clearances was 14 days.

Key words: Apolygus lucorum, emamectin benzoate, thiamethoxam, acetamiprid, residual dynamics, risk assessment
