巨星（75％磺酰脲类干燥悬浮剂）是美国杜邦公司研制的一种新型高效麦田除草剂。活性高、用量少、杀草谱广、效果好,对小麦安全。亩用0.8～1克左右（株防效达90％以上,鲜重防效80％以上）。对小麦无药害,并有一定的增产作用,一般可较不除草对照区增产一成到一成半左右。使用该药剂应掌握在杂草幼苗期用药,兑水量不少于30公斤,土壤干旱时应适当增加用水量。

Superstar (75% sulfonylurea dry suspending agent) is a new type of high efficient wheat field herbicide developed by DuPont. High activity, less dosage, broad spectrum to kill grass, good effect, safe for wheat. About 0.8 to 1 gram of mu is used (more than 90% of strain control and over 80% fresh weight control efficiency). No phytotoxicity to wheat, and a certain increase in yield, generally less herbicidal control area yield 10% to 15%. The use of the agent should be seized in weed seedlings, watered less than 30 kg, soil drought should be appropriate to increase the amount of water.
