摘　　要：在青海海北草地用狼毒净1号除草剂、2,4-D丁酯(72％乳油)和75％Lontrel G除草剂分别设三个用药量进行防除狼毒试验。狼毒净1号除草剂在1500ml/hm2用药量时对狼毒的防除效果最好,并且对禾草和阔叶牧草没有副作用,在海北有一定推广价值;2,4-D丁酯(72％乳油)对狼毒的防除效果较好、但对阔叶牧草的副作用较大;75％ LontrelG除草剂防除草地狼毒的效果较差。A test of controlling Euphorbia fisheriana was conducted using Langdujing I herbicide, 2,4-D bytyric ester (72% emulsion) and 75% Lontrel G at the level of three dose in the pasture of Haibei Prefecture of Qinghai Province.
