Embodiment 1

[0028] Sodium dodecylbenzenesulfonate 350g

[0029] Cetyltrimethylammonium Bromide 100g

[0030] Lecithin 50g

[0031] Silicone antifoam agent (AF-9000) 0.1g

[0032] Deionized water 499.9g

[0033] The preparation process is to add 500g of deionized water to the reaction kettle, start stirring, add 50g of lecithin and 0.1g of organic silicon antifoam agent, heat, stir at 35-38°C for 30 minutes until uniform, and then add dodecyl Add 350 g of sodium benzenesulfonate and 100 g of cetyltrimethylammonium bromide, add deionized water, stir for 65 minutes until uniform, and obtain 1000 g of glyphosate ammonium brine synergist.

[0034] It is used in the production of glyphosate ammonium salt solution, and its usage rate is 10%. According to the efficacy test, the killing effect on grass is better than that of the synergist control group in the market.

Embodiment 2

[0036] Sodium dodecylbenzenesulfonate 250g

[0037] Cetyltrimethylammonium Bromide 150g

[0038] Lecithin 80g

[0039] Silicone antifoam agent (AF-9000) 0.01g

[0040] Deionized water 519.9g

[0041] The preparation process is to add 520g of deionized water to the reactor, start stirring, add 80g of lecithin and 0.01g of organic silicon antifoam agent, heat, stir at 35-38°C for 30 minutes until uniform, and then add dodecyl Add 250 g of sodium benzenesulfonate and 150 g of cetyltrimethylammonium bromide, add deionized water, stir for 70 minutes until uniform, and obtain 1000 g of glyphosate ammonium brine synergist.

[0042] It is used in the production of ammonium glyphosate salt solution, and its usage rate is 10%. According to the efficacy test, the killing effect on grass is better than that of the existing synergist control group.

Embodiment 3

[0044] A kind of glyphosate ammonium salt solution synergist, it is characterized in that: comprise the following components by weight percentage:

[0045] Sodium dodecylbenzenesulfonate 25%

[0046] Cetyltrimethylammonium Bromide 10%

[0047] Alkyl Glycosides 6%

[0048] Lecithin 5%

[0049] Silicone defoamer AF-9000 0.005%

[0050] The balance is deionized water.

Abstract

The invention provides a glyphosate-ammonium aqueous solution synergistic aid and belongs to the field of herbicides. The formula of the aid comprises the following components in percentage: 25 to 35 percent of sodium dodecyl benzene sulfonate, 10 to 15 percent of hexadecyl trimethyl ammonium bromide, 6 to 10 percent of alkyl polyglucoside, 5 to 8 percent of lecithin, 0.005 to 0.1 percent of organic silicon deforming agent AF-9000 and the balance of deionized water. For solving the medical effect and cost problems in the prior art, the glyphosate-ammonium aqueous solution synergistic aid which is cheap, can be processed simply and has good effects is provided; when the aid is used for producing glyphosate-ammonium aqueous solution, the used amount is small; and medicine effect tests provethe grass killing effect of the aid is better than that of a reference aid.

Description

technical field [0001] The invention relates to a glyphosate ammonium salt synergist, more specifically, the invention relates to a glyphosate ammonium salt synergist, which belongs to the field of herbicides. Background technique [0002] Glyphosate (glyphosate) is a herbicide developed by Monsanto Company of the United States, also known as: glyphosate, Roundup, glyphosate, and phosphonic acid. The pure product is a non-volatile white solid with a specific gravity of 0.5. It melts at about 230°C and decomposes. The solubility in water at 25°C is 1.2%, insoluble in common organic solvents, and its isopropylamine salt is completely soluble in water. Non-flammable, non-explosive, stable in normal temperature storage. It has a corrosive effect on medium carbon steel and galvanized iron sheet (tinplate). [0003] The herbicidal properties of glyphosate were discovered by D.D. Baird in the United States in 1971, and developed and produced by Monsanto. By the 1980s, it had bec...
