Abstract

Abstract:

Based on the field experiments and laboratory tests, the deposition and residue characteristics of acetamiprid in celery under protected cultivation were studied, and a detection method was also established. The acetamiprid in soil and plant samples was extracted by using acetonitrile, purified by QuEChERs and detected by liquid chromagraphy-mass spectrometry. The average recoveries of acetamiprid in celery leaf, stem, root and soil were 100.2%-102.5%, 83.9%-93.5%, 97.0%-100.1% and 90.8%-94.4%, respectively. The amount of acetamiprid deposition decreased as celery leaf>soil>celery stem>celery root. The degradation curve of acetamiprid in celery leaf was in accordance with the first-order kinetic equation, and the degradation half-life of acetamiprid was 4.2-19.4 d. Seven days after application of acetamiprid with dosage of 18, 27 g·hm^-2, the residues of acetamiprid in celery leaf and stem were 0.330 0-2.570 0, 0.004 7-0.030 0 mg·kg^-1, respectively, which were below the maximum residue limit (3 mg·kg^-1) of the Chinese national standard GB 2763—2019. The results could provide scientific reference for the rational use of acetamiprid on celery under protected cultivation.

Key words: acetamiprid, protected cultivation, residue, deposition, celery
