Abstract

The invention discloses a glyphosate herbicide and a preparation technology thereof and mainly relates to the technical field of herbicides. The problem is solved that the permeability of an existingherbicide is poor, the herbicide cannot permeate into the roots of weeds, and accordingly the weeding effect of the herbicide is poor. The glyphosate herbicide comprises, by weight, 25-32 parts of glyphosate original agent, 8-13 parts of isopropylamine, 0.5-1 part of urea, 24-30 parts of soft water, 6-8 parts of stearic acid ethylene glycol ester, 0.5-1.5 parts of polyoxyethylene alkylphenol ether, 2-5 parts of polyacrylate, 0.5-2 parts of 2,4-D butyl ester, 0.1-0.5 part of fluoroglycofen-ethyl, 0.8-1.6 parts of sodium alkyl benzene sulfonate, 0.5-1.2 parts of polyglycolic acid alkyl ether, 1-3 parts of polyoxyethylene trisiloxane and 0.4-1.1 parts of alkyl glucosamide. The glyphosate herbicide has good permeability and can quickly flow into other parts of the weeds and quickly permeate into the roots of the weeds, weeding is conducted thoroughly, and the good weeding effect can be achieved.

Description

technical field

[0001] The invention relates to the technical field of herbicides, more specifically, it relates to a glyphosate herbicide and a preparation process thereof. Background technique

[0002] Glyphosate is a non-selective, non-residual herbicide that is very effective against perennial root weeds. After being incorporated into the soil, glyphosate quickly combines with iron, aluminum and other metal ions and loses its activity. No adverse effects on seeds and soil microorganisms.

[0003] In the prior art, a glyphosate-containing herbicide and its preparation method proposed by the Chinese patent with the patent announcement number CN105794836A are specifically composed of the following raw materials in parts by weight: 40-80 parts of glyphosate, 4-15 parts of fomesafen, 2-10 parts of dimethylformamide, 2-5 parts of surfactant, 1-4 parts of thickener, 1-4 parts of stabilizer, 2-7 parts of bentonite, defoaming 0-1 part of agent, 3-6 parts of self-made titanium d...

Examples

Embodiment 1

[0035] Embodiment 1: a kind of glyphosate herbicide, it comprises the component of following parts by weight: glyphosate former medicine 32 parts, isopropylamine 8 parts, urea 0.5 part, soft water 30 parts, stearic acid ethylene glycol 6 parts of grease, 0.5 parts of alkylphenol polyoxyethylene ether, and 5 parts of polyacrylate. A kind of preparation technology of glyphosate herbicide, it comprises the following steps:

[0036] Step 1, mixing the original drug of glyphosate and isopropylamine in corresponding parts by weight evenly, stirring for 130min, the concentration of the original drug of glyphosate is 95%;

[0037] Step 2: Add corresponding parts by weight of urea and polyacrylate, stir in a constant temperature water bath for 30 minutes, the temperature of the water bath is 30°C, and the stirring speed is 30 rpm / min, and in the process of stirring, slowly add an appropriate amount of soft water, divide Add 5 times, maintain the temperature while stirring and let stan...

Embodiment 2-7

[0039] Example 2-7: A glyphosate herbicide, the difference from Example 1 is that each component and its corresponding parts by weight are shown in Table 1.

[0040] Each component and parts by weight thereof in table 1 embodiment 1-7

[0041]

Embodiment 8

[0042] Example 8: a glyphosate herbicide, the difference from Example 1 is that step a is also set between the step 1 and step 2: adding 0.5 parts by weight of 2,4-D Butyl ester was stirred in a constant temperature water bath for 20 min, the temperature of the water bath was 40°C, and the stirring speed was 40 rpm / min.
