乙氧氟草醚

乙氧氟草醚用途

【用途一】
用作除草剂。芽前、芽后施用防除咖啡、针叶树、棉花、柑橘等田中单子叶和阔叶杂草。可制成乳油使用。
【用途二】
用于水稻、大豆、玉米、棉花、蔬菜、葡萄、果树等作物田防除一年生阔叶杂草和禾本科、莎草科杂草
【用途三】
本品属含氟二苯醚类，是一种超低用量的选择性、芽前芽后触杀型除草剂，杂草主要通过胚芽鞘、中胚轴吸收药剂致死。适用于水稻、大豆、小麦、棉花、玉米、油棕、蔬菜及果园等，防除阔叶杂草及某些禾本科杂草，如鸭跖草、稗草、莎草、田菁、雀麦、曼陀罗等，用量为1～2g有效成分/100m² 。如水稻移栽后4～6d，稗草芽期至1.5叶期，用24%乳油1.5～2.3mL/100m²，制成毒土均匀撒施。也可用0。5%颗粒剂撒施。用于大豆、棉花等作物在播后苗前施药，用24%乳油7.5mL/100m²，对水均匀喷雾土表。
乙氧氟草醚使用过程可能发生一定程度药害，一般半月后即可恢复。
【用途四】
低毒、触杀型除草剂。在有光的情况下发挥其除草活性。在芽前和芽后早期施用效果最佳，对种子萌发的杂草杀草谱广，能防除阔叶杂草、莎草及稗，但对多年生杂草具有抑制作用。防治对象：可防除移栽稻、大豆、玉米、棉花、花生、甘蔗、葡萄园、果园、蔬菜田和森林苗圃的单子叶和阔叶杂草。
