据报道,加拿大某科研单位在实验室试验结果,美国孟山都公司生产的除草剂“拉索”有致癌因素.为用去草胺取代拉索,1985年小面积对比试验结果表明,两种除草剂对地膜内杂草的除治效果均好,但对裸地除草的效果较差.前者的除草效果为85.7％,后者为65.7%.去草胺是一种选择性芽前除草剂,对一年生禾本科和莎草科杂草的幼芽有效,对农作物安全,但对鱼类有毒害.对温度不敏感,在较低温度下也能发挥活性,但要有一定的土壤湿度,否则效果不好.去草胺的使用方法简
It is reported that a scientific research unit in Canada in the laboratory test results, the United States produced Monsanto herbicide “cable” carcinogenic factors. In order to replace grassroots cable, small area comparison test in 1985 showed that the two herbicides The removal of weeds in the mulching film is good, but weeding on the bare land is less effective, the weeding effect of the former is 85.7% and the latter is 65.7%. The herbicide is a selective pre-emergence herbicide, Young annuals of grasses and sedge weeds are effective, safe for crops, but poisonous to fish, insensitive to temperature and active at lower temperatures, but with some soil moisture, otherwise effective Not good.
