Embodiment 1

[0030] According to the conventional preparation production method, measured in the mass percentage of the mixed herbicide finally obtained, take clomazone 60%, clomazone 10%, add agricultural adjuvant: 6% sodium methylene bis-tetrasulfonate, Sodium lignosulfonate 5%, mix evenly, and add kaolin continuously in stirring process, make whole mixture mass ratio reach 100%, and according to general procedure, form the mixed mass ratio of clomazone and clomazone as 70% wettable herbicide powder mix.

Embodiment 2

[0032] According to the conventional preparation production method, measured by mass percentage of the finally obtained mixed herbicide, take clomazone 60%, clomazone 5%, add agricultural auxiliaries: naphthalenesulfonic acid formaldehyde condensate 6.6%, wetting agent T 4.4%, white carbon black 4%, mix well, and add kaolin continuously 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 A wettable powdery mixed herbicide with grass pine mixed mass ratio of 65%.

Embodiment 3

[0034] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 50% of clomazone, 25% of clomazone, and add agricultural auxiliaries: sodium lignosulfonate 5%, dodecane Base sulfate 2%, ammonium sulfate 5%, deployment and mixing, 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 a mixture of clomazone and clomazone A water-dispersible granular mixed herbicide with a mass ratio of 75%.

Abstract

The invention belongs to the technical field of chemical synthesis and provides a mixed herbicide containing cloransulam-methyl and clomazone as active components and its preparation method and use. A mass ratio of cloransulam-methyl to clomazone in the mixed herbicide is 5-60: 1-25. The total mass of cloransulam-methyl and clomazone 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 soybean.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a mixed herbicide containing two active ingredients of clomazone and clomazone, 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 aft...
