云南省农业科研人员近期通过田间试验和气相色谱检测,研究了苯醚甲环唑在三七中的残留消解动态以及三七茎叶对其的吸收、转运与分布特性。试验结果表明:苯醚甲环唑在三七植株中的半衰期为12.3~12.8天;叶面施药后,其可被三七茎叶吸收并迅速向下传导至根部,且主要集中在须根中。苯醚甲环唑在三七不同部 Recently, the agricultural researchers in Yunnan Province studied the residual digestion dynamics of difenoconazole in Panax notoginseng and the absorption, transport and distribution of difenoconazole in its stems and leaves by field experiments and gas chromatography. The results showed that the half-life of difenoconazole in Panax notoginseng was 12.3 ~ 12.8 days. After foliar application, it could be absorbed by the stems and leaves of Panax notoginseng and rapidly down to the roots, and mainly concentrated in the fibrous roots .
