近几年来,玉米田苗后除草中,硝磺草酮扮演着重要的角色,因为其除草速度快,并且对玉米安全性高,获得了老百姓的普遍欢迎。不过,厂家的推广不当及农民的认识不足,导致了这个品种进入了错误的推广境地。2013年,从华北到华东,玉米产区由于使用效果较差几乎全军覆没,已经充分暴露了这个问题。硝磺草酮,为触杀型除草剂,属对羟基丙酮酸双加氧酶(HPPD)的抑制剂,杂草受药后,一般3~5天内即表现白化,但最终死亡与否与多种因素有关。1.打药时间必须要早,不可迟打。这是导致硝磺草酮推广
In recent years, mesotrione plays an important role in weeding in the field after weeding in the corn fields. Because of its high weeding speed and high safety to corn, it has been widely welcomed by the common people. However, improper promotion of manufacturers and lack of awareness of farmers led to the variety into the wrong promotion. In 2013, from north China to east China, the maize production area was almost completely annihilated due to its poor use effect, which has fully exposed this issue. Mesotrione, as a contact herbicide, is an inhibitor of hydroxy-pyruvate dioxygenase (HPPD). Weeds generally receive whitening within 3 to 5 days after drug treatment, but eventually they die or not Factors related. 1. The fight time must be early, can not be hit later. This is leading to mesotrione promotion
