Novel oxime esters, broad-spectrum selective post-budding herbicides. The mechanism of action is similar to that of sulfonylurea and imidazolidone herbicides, both of which are acetyllactate synthase (ALS) inhibitors. It has selective and ultra-efficient post-budding herbicidal activity on rice, common wheat and Zoysia grass, and non-budding herbicidal activity before. It has excellent effect on controlling various grasses and broadleaf weeds such as Barnyard grass, Daishigan, and Polygonum spicifolia, and is safe for rice and common wheat. The herbicide has a slow weeding speed and can inhibit the growth of weeds after application, but it must die after 2 weeks. The drugs used were moderately wide and effective in 1.5 ~ 6.5 leaf stage of Barnyard grass. At 2.5-3.5 leaf stage, 100% control can be achieved with 10g/hm2 dose; From 3.5 to 4.5 leaf stage, the dosage increased to 20g/hm2 can achieve 100% control.
