磺酰脲类除草剂甲黄隆、绿黄隆防席麦田杂草具有用药量低、防效好的特点,但也存在对当茬小麦或后茬作物安全性差等弊端.本所应用由甲黄隆、绿黄隆复配制度的新型除草剂麦草克防除麦田杂草,具有用药省、除草活性高、杀草谱广、对作物安全、价格低廉等优点.亩用麦草克5g(a.i.1.0g)对水喷雾,对小麦田主要杂草看麦娘、繁缕、猪殃殃的防效分别在95%、90%、90%以上,但对硬草防效较差.使用后一般每亩可增产25~40%,投入产出比在1.50以上.施药适期应掌握在播后至麦苗三叶期。
Sulfonylurea herbicide Huanglong, Green Huanglong maize weeds with low dosage, good control effect, but there are also shortages when the stubble crop or poor crop safety. The application by the methyl yellow, green Huanglong compound system of the new herbicide wheat grass grams of weed control wheat field, with drug province, high herbicidal activity, broad spectrum to kill grass, crop safety, low price and so on. Mu wheat straw grams 5g (a.i.1.0g) on water spray, the main wheat weeds Anemarrhenae, chickweed, Galium aparine control effect were 95%, 90%, 90%, respectively, but Poor control of the hard grass. After the use of general increase of 25 to 40% per mu, input-output ratio in more than 1.50. Application should be mastered in the sowing to the wheat seedling three-leaf stage.
