Problems solved by technology

The third is that amiloride has excellent performance, but is expensive. At present, the price of amiloride is about 10 times that of glyphosate, and its output cannot meet the market demand. Mixing the two can reduce the cost of medication
[0004] At present, there have not been several special auxiliaries for glyphosate and amiloride compound water preparations that meet the economic, environmental protection and high efficiency requirements in China. And way far

preparation example Construction

[0017] A preparation method of a special additive for glyphosate and amiloride compound water preparation, characterized in that it comprises the following steps:

[0018] Step 1: Mix LAS and fatty alcohol polyoxyethylene ether, stir evenly, add stearic acid monoglyceride, stir at 20-60°C for 4-6 minutes to obtain material a;

[0019] Step 2: Add alkyl polyether to deionized water, stir to dissolve, add lauroyl glutamic acid and alkyl sulfonate, stir evenly, add the above material a, stir and disperse for 15 minutes to obtain material b;

[0020] Step 3: Add the diffusing agent NNO to the material b, stir and mix evenly, send it to the colloid mill, and grind for 10 minutes to obtain the special additive for high-efficiency glyphosate and amiloride compound water agent.

Embodiment 1

[0022] Take the following weight materials: mix measured 5% LAS (linear sodium alkylbenzene sulfonate) and 15% fatty alcohol polyoxyethylene ether into the reaction kettle, stir well and then add weighed 1% glycerol monostearate Stir at 50°C for 5 minutes, then add 5% alkyl polyether and water into it, stir to dissolve, add quantitative 5% lauroyl glutamic acid, 5% alkyl sulfonate, stir and disperse for 15 minutes, Finally, 2% diffusing agent NNO is added to the product, stirred and mixed evenly, sent to a colloid mill, and ground for 10 minutes to obtain a special additive for high-efficiency glyphosate and amiloride compound water agents.

Abstract

A special auxiliary agent for glyphosate-picloram compound water aqua is composed of the following substances (by weight): linear alkylbenzene sulfonates (LAS), fatty alcohol polyoxyethylene ether, N-lauroyl-L-glutamic acid, alkyl sulfonate, glyceryl monostearate, alkyl polyether, a dispersing agent NNO and deionized water. A preparation method of the auxiliary agent comprises the following steps:firstly mixing LAS and fatty alcohol polyoxyethylene ether, uniformly stirring and then adding glyceryl monostearate to obtain a material a; then adding alkyl polyether into deionized water, stirringand dissolving and then adding N-lauroyl-L-glutamic acid and alkyl sulfonate, and adding the above material a to obtain a material b; and finally adding the dispersing agent NNO into the material b to obtain efficient special auxiliary agent for glyphosate-picloram compound water aqua. The auxiliary agent of the invention has a good weeding effect, also has insecticidal and sterilization efficacy, is environmentally-friendly, will not be agglomerated, is convenient to use, has a simple process, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a special additive for high-efficiency glyphosate and amiloride compound water preparation and a preparation method thereof. Background technique [0002] Glyphosate, the pure product is a non-volatile white solid, insoluble in water and common organic solvents, mainly ammonium or sodium salt, and its salt is completely soluble in water. Glyphosate is a post-emergence systemic non-selective, high-efficiency, broad-spectrum herbicide that kills weeds. By dissolving the waxy layer on the leaf diameter surface of weeds, the drug effect quickly enters the plant conduction system to cause weeds to dry up and die. It has a broad-spectrum , low toxicity, no residue, systemic conduction and excellent killing properties, non-selective to plants, all green plants, including crops. Amclopyralid is a new type of pyridinic acid herbicide developed by Tao Nongke. It is widely used in the control of ...
