本文通过对10%烯酰吗啉水乳剂在葡萄和土壤中残留消解动态和最终残留量的研究。结果表明,以375 mg/L剂量施药4次,距离最后1次施药后21 d,烯酰吗啉最终在葡萄中的残留量均<0.5 mg/kg,在土壤中均<0.7 mg/kg,烯酰吗啉在葡萄和土壤中消解较快,其残留消解动态曲线符合化学反应一级动力学方程。半衰期在葡萄上为9.3～14.8 d,在土壤中为11.2～15.8 d。 In this paper, 10% dimethomorph aqueous emulsion residues in grapes and soil digestion dynamics and final residue. The results showed that the final residues of dimethomorph in grapes were less than 0.5 mg / kg and all the soil samples were less than 0.7 mg / kg, and dimethomide was rapidly digested in grape and soil. The dynamic curve of residual digestion was in accordance with the first-order kinetic equation of chemical reaction. The half-life was 9.3-14.8 d on grapes and 11.2-15.8 d in soil.
