sulfonamide herbicide | , it is mainly used to control broad-leaved weeds in hybrid maize and soybean crops. Similar to sulfonylurea herbicides, sulfonamide herbicides are also typical acetolactate synthase inhibitors. They target ALS and are mixed inhibitors involving pyruvate and thiamine pyrophosphate (TPP), competing for the binding site of the enzyme without competing for matrix or cofactors.|
Use | The fluazolidinum belongs to triazolopyrimidine sulfonamides, and is a typical acetolactate synthase inhibitor. By inhibiting the synthesis of branched-chain amino acids, protein synthesis is blocked and plants stop growing. The residual period is long, the killing grass spectrum is wide, the soil, the stem and leaf treatment can be. Fluazolidine is used to control broad-leaved and narrow-leaved weeds in field legumes, soybeans and corn. |
