Embodiment 1

[0030] According to the conventional preparation production method, the final mixed herbicide was measured by mass percentage, taking 60% of chlorpropamide sulfentrazone, 10% of enoxydim, and adding agricultural additives: sodium methylene ditetrasulfonate 6%, wood Sodium sulfonate 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 a mixture of chlorfentrazone and sethoxydim at 70% The wettable powdery mixed herbicide.

Embodiment 2

[0032] According to the conventional preparation method, the final mixed herbicide is measured by mass percentage, taking 60% of chlorpropasulfan and 5% of sethoxydim, adding agricultural additives: naphthalenesulfonic acid formaldehyde condensate 6.6%, wetting agent T4 .4%, white carbon black 4%, mix evenly, and continuously add kaolin during the stirring process to make the mass ratio of the whole mixture reach 100%, and perform jet pulverization, and follow the general steps to form chloracetamide and sulfentrazone A wettable powdery mixed herbicide with a fixed mixing mass ratio of 65%.

Embodiment 3

[0034] According to the conventional preparation method, the final mixed herbicide is measured by mass percentage, taking 50% of chlorpropasulfan, 25% of enoxydim, and adding agricultural additives: sodium lignosulfonate 5%, dodecyl 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 the mixed mass ratio of sulfentrazone and sethoxydim It is a 75% water-dispersible granular hybrid herbicide.

Abstract

The invention belongs to the technical field of chemical synthesis and provides a mixed herbicide containing two active ingredients, namely cloransulam-methyl and sethoxydim, and a preparation method and an application of the mixed herbicide. Mass ratio of cloransulam-methyl to sethoxydim in the mixed herbicide is 5-60:1-25. The total mass of cloransulam-methyl and sethoxydim is 6-75% of the mass of the herbicide. By the use of the mixed herbicide, gramineae weeds and broadleaved weeds in the soybean field can be controlled and eliminated. The mixed herbicide provided by the invention has advantages of high herbicidal activity, wide herbicidal spectrum, long persistent period, high safety, efficient broad spectrum and good environmental compatibility, is safe to human and livestock, and is an excellent chemical herbicide for the soybean crop.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide comprising two active ingredients of chlorpropamide and sethoxydim, 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, 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 surface befo...
