Embodiment 1

[0028] Example 1 Preparation of wettable powder

[0029]

[0030] The preparation method is as follows: the above-mentioned materials are fully mixed, and after jet crushing, a white wettable powder with a uniform appearance is formed. Above-mentioned preparation index is as shown in table 1:

[0031] Table 1

[0032]

[0033] It can be seen that the wettable powder prepared in this embodiment has good indicators and meets the national standards.

Embodiment 2

[0034] Example 2 Preparation of oil suspension

[0035]

[0036] The preparation method is as follows: firstly mix the components uniformly, then shear with a high-speed shearing machine, and then sand-mill with a sand mill to form an oil suspending agent with a uniform appearance.

[0037] Above-mentioned preparation index is as shown in table 2:

[0038] Table 2

[0039]

[0040] Above index shows that the oil suspension concentrate that this example makes is good, meets the standard that the country requires to oil suspension concentrate.

Embodiment 3

[0041] Embodiment 3 preparation of water suspension

[0042]

[0043]The preparation method is: the preparation method of the water suspension is: first, take dioctyl sulfosuccinate sodium salt, alkylnaphthalene sulfonic acid condensation polymer, ethylene glycol, xanthan gum, sodium benzoate and water, mix, 1500 rpm high-speed homogeneous shearing for 30 minutes, then add glyphosate, fluorfen, quizalofop-p-ethyl and defoamer, continue 1500 rpm high-speed shearing for 30 minutes, and then sand mill by sand mill , Grind until the solid particles are less than 5um, then a water-suspending agent with uniform appearance and qualified quality can be formed.

[0044] Above-mentioned preparation index is as shown in table 3:

[0045] table 3

[0046] Test items

[0047] Above index shows that the aqueous suspension concentrate that this embodiment makes is good, meets the standard.

Abstract

The invention discloses herbicide for expanding a glyphosate weed control spectrum. The herbicide comprises the following active ingredients in parts by weight: 20-80 parts of glyphosate, 0.5-5 parts of f fluoroglycofen-ethyl and 0.5-6 parts of quizalofop-p-ethyl; besides the active ingredients, a surfactant, a carrier or / and auxiliary material and the like also can be added to prepare water aqua, emulsion in water, wettable powder, soluble powder, water dispersible granules, suspension concentrate or oil suspension. The herbicide has obvious synergized action by compounding of the three herbicides, is wide in herbicide control spectrum, long in effective duration, and small in environmental pollution, and the drug dosage and the drug times are reduced.

Description

technical field [0001] The invention relates to a herbicide for expanding the herbicide spectrum of glyphosate. Background technique [0002] Glyphosate (glyphosate) is a herbicide developed by Monsanto Company of the United States, also known as: glyphosate, roundup, glyphosate, phosphonic acid; chemical name N-(phosphonomethyl) glycine, Molecular formula: C 3 h 8 NO 5 P, the structural formula is as follows: [0003] [0004] The technical content of glyphosate is generally 95-98%. The technical glyphosate is a white solid, insoluble in water, but it has good water solubility after reacting with alkaline substances such as isopropylamine to form a salt. The most widely used 41% glyphosate water solution on the market is the water solution made of glyphosate and isopropylamine salt. The glyphosate content is 30%, and the isopropylamine salt content is 41%. The mother liquor used is generally 62% glyphosate isopropylamine salt mother liquor. [0005] Glyphosate is a...
