Abstract:ObjectiveTo establish the safety standard of acetaniprid in use, and to make sure that the pesticide residues in Lonicera japonica are not exceed with favorable effect of acetaniprid in harvest. MethodsBy the determination of the residual dynamics of acetaniprid in Lonicera japonica, the half-life of acetaniprid was solved, and then the safety standard of acetaniprid was established.ResultsThe degradation of 3 % acetaniprid EC was above 90 % after ten days and half-life of acetaniprid was 1.48~1.64 d.ConclusionIt had better to use 3 % acetaniprid EC in Lonicera japonica at least five days before harvest. The dosage of acetaniprid is no more than 18.75 g/hm2 to make sure the quality of Lonicera japonica.
