草坪阔叶杂草防除技术研究

在2001～2002年两年间,应用百草敌、2,4-D丁酯乳油、2-甲-4-氯丙酸及混合药剂对青海大学农牧学院草业科学系试验地草坪杂草进行防除试验。结果表明:百草敌、2,4-D丁酯乳油及混合药剂I对几种主要杂草防除效果比较好,与对照相比30 d能达100％,而且两种混合药剂有增效作用,扩大了除草剂的使用范围。

Study on Technology of Eradiating Broad-leaf Weed in Lawn and Grassland

The prevention and eradication effects of three herbicide varieties and mixtures (Banvel, 2, 4-Dbutylate, mecoprop, Banvel +2, 4-Dbutylate, Banvel+2, 4-Dbutylate+mecoprop) on broad-leaf weeds in lawn were studied in trial field of grassland science department of Qinghai normal universiey.The results of the two years' experiments showed that the Banvel, 2, 4-D butylate can effectively eradicate most broad-leaf weeds, and the death rate of the broad-leaf weed reached to 100% in 30 days.The two mixtures had increased efficiency and broaden scope than they used singly.
