| Abstract: | The residue dynamics of bensulfuron-methyl and quinclorac 36% WP in rice seedbed soil were studied by HPLC. And a method for the pretreatment and analysis of samples was established. The results showed that the average recoveries of bensulfuron-methyl and quinclorac were more than 80% in the paddy soil samples. The half-life of bensulfuron-methyl were 2.59-2.97, 1.52-1.59 d in Jilin province and Hunan province, and The half life of quinclorac were 10.00-12.49, 3.65-4.19 d, degrade faster. Residues were not ... |
