有读者手机发来短信反映,前年有农户油菜田化除误用“骠马”导致绝收(用量不详)。今读一农药杂志上《油菜草害发生特点及防除方法》一文,其中介绍对以禾本科杂草为主的油菜田,可选用6.9%威霸(精噁唑禾草灵)乳油40～50毫升,在杂草4叶期以前化除。骠马与威霸两者成分相同,这篇文章中的相关内容是否有误? A reader sent a text message to reflect the cell phone, two years ago, farmers have used rape fields in addition to misuse “骠 horse ” lead to absolute income (the amount is unknown). Now read a Pesticide Magazine “rape grass pest occurrence characteristics and methods of prevention and control” one article, which introduced to grass weeds-based rapeseed field, the optional use of 6.9% Wei Pa (fenoxaprop-ethyl) EC 40 ~ 50 Ml, weed before the 4-leaf weed.骠 Ma and Wei Pa both the same composition, the relevant content of this article is wrong?
