2-[4-[(6-chloro-1,3-benzoxazol-2-yl)oxy]phenoxy]-2-methyl-propanoic acid - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| action characteristics | The purification (R-body) of the active ingredient excluding the inactive part (S-body), jinoxazole grass is a selective, in-penetration type Post-seedling stem and leaf treatment agent. The active ingredients are absorbed by the stems and leaves and then conducted to the growing points of the leaf base, Internode meristem and root, which are rapidly converted into phenoxy free acids, inhibit fatty acid biosynthesis, and damage the growing points and meristems of weeds, the action was rapid, and the growth was stopped within 2-3 days after application. In 5-7 days, the Heart Leaf became green and purple, and the meristem became brown. Detoxification in drug-resistant crops is broken down into inactive metabolites. |
| biological activity | Fenoxaprop-P-ethyl is a hetero-epoxyphenoxypropionic acid herbicide. |
