sulfonamide herbicide | chloroester sulfonamide is a sulfonamide herbicide newly developed by Dow Yinong Company in the United States. It is mainly used to spray stem and leaf to control broad-leaved weeds in soybean fields. The agent is absorbed and accumulated in the growth point by the weed leaves and roots, inhibiting acetolactate synthase (ALS), affecting the synthesis of protein, and causing the weed to stop growing and die. Field efficacy tests showed that chlorosamine had a good control effect on the broad-leaved weeds of Commelina communis, Polygonum chinensis and Ambrosia, and had a strong inhibitory effect on bitter cabbage and Sonchus. Sulfonamide herbicides are similar to sulfonylurea herbicides. Sulfonamide herbicides are also typical acetolactate synthase inhibitors. Targeting ALS, they are mixed inhibitors involving pyruvate and thiamine pyrophosphate (TPP), competing for the binding site of the enzyme, but not for the matrix or cofactors. Sulfonamide herbicides are a new class of acetolactate synthase inhibitors developed by Dow Yinong Company in the United States. Its main structural form is triazolopyrimidinesulfonamide. There are currently 6 varieties, all of which are dry field herbicides, including oximuron, methoxysulfuron, chlorosulfuron, and dichlorosulfuron. Amine, difluorosulfuron and pentafluorosulfuron. Zazimuron is safe for soybean, corn, wheat, barley, pea, alfalfa, clover, etc., and has no adverse effect on subsequent crops. Methodoxamine is used to control most of the main broad-leaved weeds in wheat, barley, and rye fields after seedlings. It can be used before and after seedlings to control most of the main broad-leaved weeds in corn fields. Chloroester sulfonamide is mainly used to prevent and remove broadleaf weeds before and after seedling in soybean fields, and has special effects on Xanthium sibiricum, ragweed, trifid leaf ragweed, sweet potato and Abutilon. Dichlorosulfamethoxamine is a soybean field herbicide. Bifudoxamine is mainly used to control broad-leaved weeds in winter wheat fields after seedlings. Pentafosulforamine is a recently reported herbicide, mainly used to control weeds in rice fields. (2015-08-29). |
