sulfosulfuron - Reference Information
| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | sulfonylsulfuron-methyl is a new developed sulfonylurea super-efficient herbicide in recent years, its chemical name is 1-(4, 6-dimethoxypyrimidin-2-yl)-3-(2-ethylsulfonyl imidazo [1,2-a] pyridin-3-yl) sulfonylurea. |
| mechanism of action | sulfonylcarbene is a systemic herbicide, which is mainly absorbed by plant roots and leaves. The product is a branched-chain amino acid synthesis inhibitor, by blocking the plant essential amino acids and isoleucine biosynthesis, so that cells stop dividing, plants stop growing and then dry and die. |
| Overview | sulfonylsulfuron is an systemic herbicide that is mainly absorbed by plant roots and leaves. The product is a branched-chain amino acid synthesis inhibitor, by blocking the plant essential amino acids and isoleucine biosynthesis, so that cells stop dividing, plants stop growing and then dry and die. |
| Use | sulfonylsulfuron is an organic substance that can be used as a herbicide. |
| soil degradation | The adsorption of sulfonylmethyl in soil is physical adsorption, and the adsorption constant (Kd) it is 3.05 of red soil in Jiangxi, 1.63 of paddy soil in Taihu Lake and 1.15 of black soil in Northeast China. Red soil in Jiangxi is medium mobile, while Paddy soil in Taihu Lake and black soil in Northeast China are mobile; the photolysis half-life of the soil surface was 22.6 h, and the photolysis of pesticide was difficult on the soil surface. |
