摘　　要：以多年生杂草空心莲子草 (Alternantheraphiloxeroides) 为生测材料对内吸传导型除草剂草甘膦(Glyphosate)配方的药效进行了评价 ,以高、低两种浓度处理生长均匀的空心莲子草 ,通过地上和地下部分的毒害症状的分级记录与统计分析 ,比较不同配方的药效 ,筛选出最佳配方。试验结果表明 ,以空心莲子草为生测材料评价草甘膦药效是一种准确。A new technique was developed that a perennial weed, Alternanthera philoxeroides, was used as bioassay materials to evaluate the efficacy of glyphosate formulation, a translocated herbicide. Alligator weed growing well was selected and plotted, and then treated with high and low concentrations. After having a grading record and statistical analysis of the symptoms of the weed's aerial and subterraneous parts, the efficacy of glyphosate formulations tested was compared. The results showed that formulation 2# was the best formulation. The experimental results also indicated that it was an accurate and practical way to use Alternanthera philoxeroides to bioassay the efficacy of glyphosate.
