Embodiment 1

[0031] According to the conventional preparation method, the final mixed herbicide is measured by mass percentage, taking 60% of chlorfentrazone and 10% of metolachlor, and adding agricultural additives: sodium methylene ditetrasulfonate 6% , Sodium lignosulfonate 5%, mix well, and continuously add kaolin during the stirring process to make the mass ratio of the whole mixture reach 100%, and follow the general steps to form the mixed mass of chlorfentrazone and metolachlor A wettable powdery mixed herbicide with a ratio of 70%.

Embodiment 2

[0033] According to the conventional preparation production method, the final mixed herbicide was measured by mass percentage, taking 60% of chlorfentrazone and 5% of metolachlor, adding agricultural additives: naphthalenesulfonic acid formaldehyde condensate 6.6%, moist T 4.4%, white carbon black 4%, mix and mix, and continuously add kaolin during the stirring process to make the mass ratio of the whole mixture reach 100%, perform jet pulverization, and follow the general steps to form chloracetamide and iso A wettable powdery mixed herbicide with a 65% mass ratio of metolachlor.

Embodiment 3

[0035] According to the conventional formulation production method, the final mixed herbicide was measured by mass percentage, taking 50% of chlorfentrazone and 25% of metolachlor, adding agricultural additives: sodium lignosulfonate 5%, 12% Alkyl sulfate 2%, ammonium sulfate 5%, mix well, and continuously add kaolin during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and follow the general steps to form chlorfentrazone and metolachlor A water-dispersible granular hybrid herbicide with an amine mixing mass ratio of 75%.

Abstract

The invention belongs to the technical field of chemical synthesis and provides a mixed herbicide containing cloransulam-methyl and metolachlor as active components and its preparation method and use. A mass ratio of cloransulam-methyl to metolachlor in the mixed herbicide is 5-60: 1-25. The total mass of cloransulam-methyl and metolachlor is 6-75% that of the mixed herbicide. The mixed herbicide can prevent and remove various gramineous weed and broadleaf weed in the soybean field. The mixed herbicide has the advantages of high weeding activity, wide weeding spectrum, lasting action, high safety, high efficiency, wide spectrum, good environmental compatibility and good safety to human and animals and can be used as a high-quality chemical herbicide for crops.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide comprising two effective ingredients of chlorfentrazone and metolachlor, and a preparation method and application of the mixed herbicide. Background technique [0002] Cloransulam-methy (cloransulam-methy), chemical name: 3-chloro-2-(5-ethoxy-7-fluoro[1,2,4]triazole[1,5-c]pyrimidine-2- Sulfonyl) methyl aminobenzoate is a sulfonamide herbicide. It has systemic conductivity. The roots and stems and leaves of weeds can absorb the drug, and can conduct upward and downward through the xylem and phloem, and finally accumulate in the plant In the meristem, by inhibiting acetolactate synthase and inhibiting the biosynthesis of branched-chain amino acids, the protein synthesis in the weeds is blocked, resulting in the weeds' growth stagnation and death. The agent has both stem and leaf treatment effect and soil sealing effect. The main purpose is to spray on the soil surfac...
