摘要： SYP-1924 is a new kind of herbicide developed by Shenyang Scicncreat Chemicals. This study has been carried out to investigate the environmental fate of SYP-1924 in rice-field system. An analytical method utilizing high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection was described for the determination of new kind of herbicide SYP-1924 in rice, rice straw, soil and water. The dissipation of SYP-1924 in soil, water and rice straw was determined using the proposed method. The results showed that dissipation of SYP-1924 in rice straw and water were found to be very faster with half-life time shorter than 1.5 days. The half-life value of SYP-1924 was observed to be 4.5 days in soil. The ultimate residues of SYP-1924 in rice were found to be below the limits of the detection at level of recommended and 1.5 times recommended dosage with an interval date of 70 days.
