乙氧氟草醚在花生上的残留动态研究

Study on Residues of Herbicide Oxyfluorfen in Peanut Plant and Soil

为防止新除草剂乙氧氟草醚对农业生态环境污染,作者进行了该农药在花生上残留动态试验研究。结果表明:乙氧氟草醚在土壤中的半衰期11～12天,生长后期,花生壳、花生仁及花生植株中均未检出。同时提出了乙氧氟草醚在花生上的安全使用准则。

The residues of oxyfluorfen have been determinated with GC.The results showed that the dispersion of oxyfluorfen in soil follows index equation (C=Coe-kt), the half-life was about 11-12 days in soil. The residues of oxyfluorfen in peanut plant of mature period is not detectable.The guidelines for safely application of herbicide oxyfluorfen in the peanut field have been provided.
