摘要
本试验为腈菌唑在辽宁、江苏两地的两年残留测定，作物为小麦。分析目标为麦粉、麦杆、青植株、土壤，四种试材分析方法的添加回收率均为７５％以上。１９９３年土壤的半衰期辽宁、江苏分别为２７．２天和２３．７天，小麦青植株的半衰期辽宁、江苏分别为２．１天和２．５天；１９９４年土壤的半衰期辽宁、江苏分别为２５．８天和３６．７天，小麦青植株的半衰期辽宁、江苏分别为４．３天和３．３天。试验施药剂量为２５毫克／公斤（２．５克／亩）及５０毫克／公斤（５．０克／亩）两种，在收获期小麦麦粉及麦杆中的残留量都低于参照的允许残留量０．１毫克／公斤及２．０毫克／公斤，安全间隔期为２０天。分析结果表明腈菌唑对小麦使用安全。
The experiment was carried out from 1993 to 1994 in Liaoning and Jiangsu for measuring residue of myclobutanil in wheat grain,stalk,living plant and soil.The four fortification recoveries were greater than 75%.In 1993,the half-lives of degradation in soils in Liaoning and Jiangsu were 27.2 days and 23.7 days and in living plants were 2.1 days and 2.5 days respectively.In 1994,the half-lives in soils in and Jiangsu were 25.8 days and 36.7 days and in living plants were 4.3 days and 3.3 days respectively.The amounts of used myclobutanil were 25mg/kg and 50mg/kg.The residues of wheat grain and stalk were less than 0.1mg/kg and 2.0mg/kg of tolerance respectively.The safe limit is not less than 20 days.The results showed that myclobutanil is safe for wheat.
