咪唑磺隆

咪唑磺隆用途

1、 通过根部吸收，然后输送至整株植物，对支链氨基酸生物合成的关键酶乙酰乳酸合成酶（ALS）具有强烈的抑制作用。抑制杂草尖芽生长，阻止根部或幼苗的生长发育，从而使之渐渐死亡。可在芽前或水稻移植后10～15d使用，防除包括稗草在内的大多数一年生杂草和牛毛毡、萤蔺、水莎草、水芹、矮慈姑等多年生杂草。推荐使用量30g/hm2。与其他除草剂混用可增强对稗草的防效。

2.用作除草剂。通过根部吸收，输送至整株植物，对支链氨基酸生物合成的关键酶———乙酰乳酸合成酶，具有强烈的抑制作用。可抑制杂草尖芽生长，阻止根部或幼苗的生长发育，使其渐渐死亡。可防除大多数一年生和多年生阔叶杂草及莎草科杂草，如牛毛毡、慈姑、莎草、水芹、稗草等，也能防除恶性杂草，如野慈姑等。
