杜邦公司于80年代初期开发的磺酰脲类除草剂磺隆(chlorsulfuron)具有高效,低毒,选择性强,用量低,效果好。杀草谱广的特点,每公顷用量(有效量)10～60克,可防治麦类作物及亚麻田中绝大多数阔叶和部分禾本科杂草。其活性之高,选择性之强,从而成为在第五届国际农药会议上获得农药研究奖的唯一品种。我们于1984年起对此药的使用技术等进行了初步试验。 The sulfonylurea herbicide chlorsulfuron developed by DuPont in the early 1980s has high efficiency, low toxicity, high selectivity, low dosage and good effect. Broad spectrum of herbicides to kill, the amount per hectare (effective amount) 10 to 60 grams, can prevent wheat crops and flax fields most of the broadleaf and some grass weeds. Its high activity and high selectivity make it the only variety that has received the Pesticide Research Award at the Fifth International Conference on Pesticides. We started in 1984 on the use of technology and other drugs conducted a preliminary test.
