Dissipation and Residues of Emamectin Benzoate Study in Paddy Under Field Conditions

Abstract

The objective of this experiment was not only to provide a simple residue analytical method to evaluate the safe application rate of Emamectin Benzoate for paddy crops but also to give a suitable recommended dosage in paddy crops. Paddysamples were detected using HPLC-MS/MS. The half-lives of emamectin benzoate in paddy plants, water and soil were 2.04-8.66days, 2.89-4.95days and 3.65-5.78days with a dissipation rate of 90% over 7days after application, respectively. Low residues and short half-life suggested that Emamectin Benzoate could be safely used in paddy crops with the suitable dosage and application.
