Embodiment 1

[0029] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 60% of sulfazone, 10% of imazethapyr, add agricultural adjuvant: 6% of sodium methylene bis-tetrasulfonate, lignin sulfonate 5% sodium bicarbonate, 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 wettable powder with a mixed mass ratio of 70% of clofenac and imazethapyr mixed herbicides.

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 imazethapyr, and add agricultural auxiliaries: 6.6% of naphthalenesulfonic acid formaldehyde condensate, 4.4% of wetting agent T , white carbon black 4%, deployment and mixing, and constantly add kaolin during the stirring process, so that the mass ratio of the whole mixture reaches 100%, carry out jet milling, and according to the general steps, form the mixed mass ratio of sulfazone and imazethapyr 65% wettable herbicide powder mix.

Embodiment 3

[0033] According to the conventional preparation production method, measured by the mass percentage of the finally obtained mixed herbicide, take 50% of clofensulfame, 25% of imazethapyr, and add agricultural auxiliaries: sodium lignosulfonate 5%, lauryl sulfate 2%, 5% ammonium sulfate, 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 a compound with a mixed mass ratio of 75%. Water dispersible granular mixed 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 imazethapyr, and a preparation method and an application of the mixed herbicide. Mass ratio of cloransulam-methyl to imazethapyr in the mixed herbicide is 5-60:1-25. The total mass of cloransulam-methyl and imazethapyr 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 clofenac and imazethapyr, and a preparation method and application of the mixed herbicide. . Background technique [0002] Diflufenican, chemical name: 3-chloro-2-(5-ethoxy-7-fluoro[1,2,4]triazol[1,5-c]pyrimidin-2-ylsulfonyl Acyl)aminobenzoic acid methyl ester, 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 plant meristems In tissues, by inhibiting acetolactate synthase and 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 ...
