新型农药氰氟草酯是芳氧苯氧羧酸类除草剂中唯一对水稻具有高度安全性的品种,并且对禾本科杂草具有高效的内吸传导性作用。目前主要用于水稻秧田、水直播、旱直播稻田,防除稗草、千金子、牛筋草等大多数恶性禾本科杂草,需求呈现上升之势。水稻田中千金子危害较严重,而氰氟草酯对4叶期前的千金子表现出极高的杀草活性,其它药剂无法与之相比。氰氟草酯和陶氏的使它隆混用,杀灭阔叶草效果较好。2007年前,我国氰氟草酯进口 Cyhalofop esters, the new pesticides, are the only species of aryloxyphenoxycarboxylic acid herbicides with high safety to rice, and have high internal absorption and conductivity of gramineous weeds. At present, mainly for rice seedling, water direct seeding, dry direct seeding rice fields, control barnyardgrass, Qianjinzi, tendon grass and most other malignant grass weeds, the demand showed an upward trend. Thousands of gold in paddy field more serious harm, and Cyhalofop-ethyl on the four-leaf period before the gold showed a high activity of herbicides, other agents can not be compared. Cyhalofop ester and Dow make it Lung mixed use, kill broadleaf better. Before 2007, China Cyhalofop-butyl was imported
