为探讨新除草剂麦草灵在土壤和小麦体系中的残留及消解，采用田间现场试验的方法，在我国东西部进行了数年研究。实验现场设在四川成都和江苏无锡。研究时间跨度从１９８５年至１９９２年。结果显示，麦草灵在土壤中易消解，其消解半衰期为１２天～１８天；在推荐的施药剂量下，麦草灵在小麦中的残留低于０．０５ｍｇ／ｋｇ。本研究结果可为麦草灵除草剂的卫生学评估提供依据。
In order to investigate the residue and digestion of the new herbicide wheatgrass in soil and wheat system, a field experiment was conducted in the field for several years in our country. The experiment site is located in Chengdu, Sichuan and Wuxi in Jiangsu. The study spanned from 1985 to 1992. The results showed that wheatgrass was easily digested in the soil and its digestion half-life ranged from 12 days to 18 days. Wheatgrass residue was less than 0.05mg / kg at the recommended application rate. The results of this study may provide the basis for the hygiene evaluation of wheat grass herbicide.
