精噁唑禾草灵在我国最早登记在1993年,由德国拜耳公司首次登记在油菜、花生、大豆、棉花等旱地阔叶作物,用于防除一年生禾本科杂草。在1998年由德国拜耳公司开发加入安全剂,登记在春小麦和冬小麦上防除一年生杂草。21世纪初,该有效成分原药和制剂开始国产化生产,现已在生产上大面积推广应用,用于旱地禾本科杂草防除效果良好。近年来,有企业把精噁唑禾草灵有效成分复配开发登记在水稻田使用。通过生产实践表明,精噁唑禾草灵以及复配制剂在水稻直播田和移栽田应用,施用技术应引起重视,否则会发生药害事故,严重时影响水稻的产量。
Fenoxaprops was first registered in China in 1993. It was first registered by Bayer in Germany as dry-leaf broadleaf crops such as rapeseed, peanut, soybean and cotton for the control of annual grass weeds. Developed by Bayer AG in Germany in 1998 to contain safeners and registered for control of annual weeds on spring wheat and winter wheat. The beginning of the 21st century, the active ingredient of the original drug and preparation of domestic production, has been widely applied in the production of large areas for grassland weed control effect is good. In recent years, some enterprises have formulated and registered the active ingredients of fenoxaprop in the paddy field. The production practice shows that fenoxaprop and the compound formulation are applied in direct seeding field and transplanting paddy field, and the application technique should pay attention to it. Otherwise, phytotoxicity accident will occur and seriously affect the yield of rice.
