Embodiment 1

[0031] According to the conventional preparation production method, the mass percentage of the finally obtained mixed herbicide is measured, taking 60% of clofensulfame and 10% of metolachlor, and adding agricultural adjuvant: 6% of sodium methylene bis-tetrasulfonate , sodium lignosulfonate 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 of sulfachlor and metolachlor Ratio of 70% wettable powder mixed herbicide.

Embodiment 2

[0033] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 60% of clofensulfame and 5% of metolachlor, add agricultural auxiliaries: 6.6% of naphthalenesulfonic acid formaldehyde condensate, wet Agent T 4.4%, white carbon black 4%, deployment and mixing, and continuously add kaolin during the stirring process, so that the mass ratio of the whole mixture reaches 100%, carry out jet milling, and follow the general steps to form the The mixed mass ratio of metolachlor is 65% wettable powder mixed herbicide.

Embodiment 3

[0035] According to the conventional preparation production method, the mass percentage of the mixed herbicide finally obtained is measured, taking 50% of clofensulfame and 25% of metolachlor, and adding agricultural adjuvants: sodium lignosulfonate 5%, dodecyl Alkyl sulphate 2%, ammonium sulphate 5%, mix well, and kaolin is added continuously during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and according to the general steps, the formation of sulfafelam and metofen A water-dispersible granular mixed 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 active ingredients of clofenac-sulam and metolachlor, and a preparation method and application of the mixed herbicide. Background technique [0002] Cloransulam-methy, chemical name: 3-chloro-2-(5-ethoxy-7-fluoro[1,2,4]triazol[1,5-c]pyrimidine-2- Sulfonyl) methyl aminobenzoate, belongs to sulfonamide herbicides, has systemic conductivity, weed roots and stems and leaves can absorb pesticides, and can conduct upward and downward through xylem and phloem, and finally accumulate in plants In the meristem, by inhibiting acetolactate synthase and inhibiting the biosynthesis of branched-chain amino acids, protein synthesis in weeds is blocked, resulting in growth stagnation and death of weeds. The agent has both stem and leaf treatment effects and soil sealing effect. Its main purpose is to spray the soil surface before planting, and use it before and...
