Embodiment 1

[0029] According to the conventional preparation production method, measured in the mass percentage of the mixed herbicide finally obtained, take 60% of sulfazone, 10% of bentazone, add agricultural adjuvant: 6% of sodium methylene bis-tetrasulfonate, wood Sodium sulfonate 5%, mix well, and add kaolin continuously during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and follow the general steps to form a mixed mass ratio of clofensulfame and bentazone with a mass ratio of 70% A wettable powdered herbicide mix.

Embodiment 2

[0031] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 60% of sulfazone, 5% of bentazone, add agricultural auxiliaries: 6.6% of naphthalenesulfonic acid formaldehyde condensate, wetting agent T 4.4%, white carbon black 4%, blended and mixed, and kaolin was continuously added during the stirring process, so that the mass ratio of the whole mixture reached 100%, and air-jet milling was carried out, and according to the general steps, the formation of cloxazone and bimazone A wettable powder mixed herbicide with a mixing mass ratio of 65%.

Embodiment 3

[0033] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 50% of sulfazone, 25% of bentazone, and add agricultural auxiliaries: sodium lignosulfonate 5%, lauryl Sulfate 2%, ammonium sulfate 5%, mix well, and add kaolin continuously during the stirring process, so that the mass ratio of the whole mixture reaches 100%, and follow the general steps to form a mixed mass ratio A 75% water dispersible granular herbicide mix.

Abstract

The invention belongs to the technical field of chemical synthesis and provides a mixed herbicide containing two active ingredients, namely cloransulam-methyl and bentazone, and a preparation method and an application of the mixed herbicide. Mass ratio of cloransulam-methyl to bentazone in the mixed herbicide is 5-60:1-25. The total mass of cloransulam-methyl and bentazone is 6-75% of the mass of the herbicide. By the use of the mixed herbicide, broadleaved weeds and cyperaceae 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 clofenac-sulam and bentazone, 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 an...
