摘　　要：为评价菌核净在烟草上的安全性,采用气相色谱法检测,研究了菌核净在湖南湘西地区土壤及其烟叶上残留消解动态。结果表明:以100ga.i./hm2施药,菌核净在土壤中消解较慢,半衰期为14.6d,在烟草中消解较快,半衰期为5.6d。Research on residue dynamics and environmental safety of dimetacholne in tobacco was conducted. Experiments were carried out in Xiangxi district. The results showed that the half-life of dimetachlone was 14.6 days in soil and 5.6 days in tobacco.
