Embodiment 167

[0047] Embodiment 167% sulfentrazone · chlorimuron-methyl water-dispersible granules

[0048] Sulfentrazone 62%, Chlorsulfuron-methyl 5%, Dispersant polycarboxylate sodium salt 3%, Calcium lignosulfonate 1%, Wetting agent a-sulfo fatty acid methyl ester 0.5%, a-olefin sulfonic acid Sodium 0.5%, fatty amide N-methyl taurine sodium salt 1.0%, disintegrant urea 1.5%, sodium sulfate 1.5%, kaolin supplement 100%. After the mixture is fully mixed and uniform, carry out ultrafine airflow pulverization to obtain 750-mesh fine powder, and then knead the obtained fine powder with an appropriate amount of water in a kneader, and then granulate it through an extrusion granulator. Dry at ℃ to obtain 67% sulfentrazone·chlorimuron-methyl water-dispersible granules.

Abstract

The invention discloses a herbicidal composition containing sulfentrazone and chlorimuron-methyl and an application thereof. The composition uses sulfentrazone and chlorimuron-methyl as active components. The herbicidal composition of the present invention can effectively control broad-leaved weeds and grass weeds such as cocklebur, quinoa, and morning glory in soybean fields and peanut fields, and the control effect is obviously higher than that of sulfentrazone or chlorimuron-methyl alone. prevention effect. In addition, the use of the composition can not only improve the efficacy of the drug, reduce the dosage of the drug, save economic costs, greatly reduce the dosage of each active substance, reduce the residue of the drug in the environment, and at the same time delay the emergence of weed resistance , to prolong the service life of the agent, which has important ecological and environmental significance.

Description

technical field [0001] The invention relates to a compound herbicidal composition and its application, in particular to a herbicidal composition containing sulfentrazone and chlorimuron-methyl and its application, and belongs to the technical field of pesticides. Background technique [0002] Sulfentrazone, English common name: Sulfentrazone, chemical name: N-(2,4-dichloro-5-(4-difluoromethyl-4,5-dihydro-3-methyl-5-oxo -1H-1,2,4-triazol-1-yl)phenyl)methanesulfonamide. Sulfentrazone is a tan solid with a melting point of 121–123°C and a vapor pressure of 1.3×10 -4 MPa (25°C), the specific gravity is 1.21g / ml (20°C), the solubility in water is 0.11 (pH6), 0.78 (pH7), 16 (pH7.5) (mg / g, 25°C). Sulfentrazone is a protoporphyrinogen oxidase inhibitor. By inhibiting protoporphyrinogen oxidase, excess protoporphyrin IX is produced in plant cells. The cell membrane, sac membrane, etc. are ruptured, the lysate in the cell leaks out, and the cell dries up and dies. Sulfentrazone ca...
