Study on the Residual Digestion Characteristics of Emamectin Benzoate on Facility Pepper Applied by the Powder Method
In order to explore the residual digestion characteristics of emamectin benzoate on pepper applied by the powder method,this experiment adopted a powder machine to apply emamectin benzoate on the peppers grown in the greenhouse,and collected pepper samples at different time points after application.Meanwhile,ultra-high performance liquid chromatography-tandem mass spectrometry was established to determine the residual emamectin benzoate in pepper plants.The results showed that the residue degradation of emamectin benzoate on pepper was subject to the first-order reaction kinetics,and the half-life of emamectin benzoate on pepper was 2.3 d.The final residue of emamectin benzoate in pepper collected 5 d after application met the quality and safety standard.This study provided a reference for the pesticide residual safety after the use of powder method in the production of pepper in the facility.
