| 摘 要： | 目的]探讨氟吡磺隆对直播稻田杂草的防除效果,观察其对水稻的安全性,确定其最佳使用剂量。方法]以水稻品种武香粳833为试材,通过小区试验和大区示范试验调查了10%氟吡磺隆WP对水稻直播田1年生阔叶杂草和莎草科杂草等的防治效果及安全性。结果]10%氟吡磺隆WP在水稻直播田使用,不仅能有效防除3～5叶期稗草,而且对7叶以上稗草也有很好的控制作用,同时能防除鸭舌草、水苋菜等阔叶杂草和异型莎草。10%氟吡磺隆WP在常规用量300～600g/hm~2对水7 500 kg时对稗草、鸭舌草和异型莎草的株防效和鲜重防效均超过90%,持效期达40d以上,且对水稻安全性高,对水稻产量无影响。结论]氟吡磺隆对直播稻田杂草的防效或高于或相当于同类商品化除草剂,且价格低廉,适合大面积推广应用。
