为了评价唑草酮在水稻上使用后的残留动态,在天津、南京两地同时进行了唑草酮在水稻上的残留动态试验。结果表明:唑草酮在水稻植株上的半衰期为5.2~5.7d,在土壤中的半衰期为1.3~2.3d,在稻田水中的半衰期为0.8~1.4d;收获的水稻糙米中唑草酮的残留量均未检出。唑草酮在糙米中最高残留限量(MRL值)推荐值为0.05mg/kg。
In order to evaluate the residue dynamics of oxacillin on rice, the residual dynamic test of oxacloprid on rice was carried out in Tianjin and Nanjing at the same time. The results showed that the half-life of oxacillin in rice was 5.2-5.7d, the half-life in soil was 1.3-2.3d, and the half-life in paddy water was 0.8-1.4d. The residuals of oxacillin in rice brown rice The amount were not detected. The recommended maximum MRL value for pyraclostrobin in brown rice is 0.05 mg / kg.
