Description

Technical Field

[0001] The present invention relates to the technical field of herbicidal pesticides, and in particular to a synergistic herbicidal pesticide composition and a production process thereof. Background Art

[0002] Herbicides are one of the essential pesticides in agricultural production. They are widely used to control weeds in the field and help crops obtain better growth space and nutritional resources. However, with the increasing demand for high-efficiency, low-toxicity and low-residue herbicides in agricultural production.

[0003] Traditional herbicides (such as glyphosate, diuron, etc.) are effective in weed control, but usually require higher dosages and are difficult to achieve optimal effects on different weed types. Long-term use can lead to weed resistance problems and reduce weed control effects. In addition, some herbicides are toxic to crops and require precise dosage control.

[0004] With the increase in the use of herbicides, resistant weeds spread, affecting crop yields and increasing the cost of weed control. To address this problem, the development of new herbicide compositions has become an important direction, especially the use of synergists that can improve the weed control effect and inhibit the development of resistance. Synergists are a class of chemical substances that can significantly improve the effect of herbicides, by improving the permeability, absorption rate and biological activity of herbicides, thereby enhancing the weed control effect. Reasonable combination of synergists and herbicides can improve weed control efficiency, reduce the dosage used, and reduce environmental pollution.

[0005] At present, some synergistic herbicidal pesticide compositions on the market have been applied in actual production, but most products still have some problems. For example, the selection and ratio of synergists are not reasonable, resulting in unsatisfactory weed control effects; or there are deficiencies in environmental adaptability and safety, and they cannot be widely used in agricultural production under different climate and soil conditions; in addition, the production process of synergistic pesticide compositions is relatively complicated, the cost is high, and the production efficiency is low, which also limits their popularization and application.

[0006] To this end, we propose a synergistic herbicidal pesticide composition and a production process thereof. Summary of the invention

[0007] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a synergistic herbicidal pesticide composition and a production process thereof.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a synergistic herbicidal pesticide composition, comprising the following components in parts by weight: 45%-60% of glyphosate, 8%-14% of sodium alkylbenzene sulfonate, 5%-11% of cocamidopropyl dimethyl betaine, 3%-9% of polyoxyethylene isooctylphenol polyoxyethylene ether, 10%-16% of isopropyl alcohol, 5%-11% of xylene, 20%-26% of water, 2%-5% of hydroxyethyl cellulose, 1%-4% of antioxidant and 0.5%-3.5% of colorant.

[0009] Preferably, the antioxidant is sodium sulfite.

[0010] A production process of a synergistic herbicidal pesticide composition comprises the following steps:

After the glyphosate solution is completed, add sodium alkylbenzene sulfonate and cocamidopropyl dimethyl betaine and stir again to ensure that these ingredients are completely dissolved and evenly dispersed in the solution;

[0014] S4: Add isopropyl alcohol and xylene to the mixing container to help glyphosate better penetrate the plant epidermis and ensure that there is no oily substance or suspended matter to ensure stability during subsequent mixing;

[0015] S5: Slowly add the glyphosate solution and solvent phase solution to the water phase solution. Keep stirring slowly and evenly during mixing to ensure that all ingredients are evenly blended. Add antioxidants and colorants to help the product be easier to identify and control during use.

[0016] S6: Ensure that the pH value of the product is maintained at 6.5. After adjustment, filter the entire solution through a fine mesh filter to remove possible impurities or solid particles to ensure the final quality of the product;

[0017] S7: After filtration, the product can enter the packaging stage, be labeled, and be stored accordingly according to the product characteristics.

[0021] The present invention provides a synergistic herbicidal pesticide composition and a production process thereof, which has the following beneficial effects:

[0022] 1.

[0023] 2. The synergistic herbicidal pesticide composition and its production process can significantly improve the activity of the herbicide through the action of the synergist, so that the dosage can be reduced. Reducing the dosage helps to reduce environmental pollution, reduce the accumulation of chemical residues in soil and water sources, and thus reduce the negative impact on the ecological environment.

[0024] 3. A synergistic herbicidal pesticide composition and its production process. The synergist helps to improve the effectiveness of the herbicide and reduce the emergence of weed resistance. The higher weed control efficiency can effectively eliminate weeds and reduce the accumulation of resistant weeds, thereby maintaining the effectiveness of the herbicide in long-term use and avoiding the spread of resistant weeds.

[0025] 4. This synergistic herbicidal pesticide composition and its production process can reduce the toxic effects of glyphosate on crops by rationally matching the various components. By optimizing the formula of the herbicide, it can ensure that glyphosate is only toxic to weeds and has minimal impact on crops, thereby improving the safety and yield of crops.

[0026] 5. The synergistic herbicidal pesticide composition and its production process improve the stability and efficiency of the production process through precise raw material ratio, dissolution and stirring control. Through a reasonable production process, not only the production cost is reduced, but also the production efficiency of the product is improved, and the large-scale application of the product is promoted.

[0064] Sodium alkylbenzene sulfonate is used to reduce the surface tension of the herbicide, allowing glyphosate to better penetrate the leaf surface of the weeds. By reducing the surface tension, sodium alkylbenzene sulfonate helps glyphosate break through the wax layer of the weeds, thereby improving its permeability, allowing the herbicide to enter the plant more quickly and effectively and take effect;

[0065] Cocamidopropyl dimethyl betaine is a modified surfactant. Its main function is to enhance the stability of glyphosate and optimize its distribution on the surface of plants. It can also reduce the irritation of glyphosate to the environment, especially during the spraying process, and reduce the damage to non-target plants or soil.

[0066] Polyoxyethylene isooctylphenol polyoxyethylene ether can further improve the wettability and adhesion of glyphosate, which means that the adhesion of glyphosate on weed leaves is enhanced and it can remain on the surface of plants for a longer time. For some stubborn weeds, polyoxyethylene isooctylphenol polyoxyethylene ether can effectively increase the activity of glyphosate and prevent glyphosate from evaporating or losing too quickly, ensuring that it is fully absorbed by the weeds.

[0067] Isopropyl alcohol is a chemical component commonly used in solvents and penetrants. It is mainly used in herbicide formulations to increase the solubility of glyphosate. It also helps to improve the ability of glyphosate to dry quickly during spraying, reduce water evaporation, and improve the efficiency of application. Its volatility allows glyphosate to dry faster and adhere to the surface of weeds after spraying, thereby reducing the impact of rain erosion and improving the durability of the weed control effect;

[0068] Xylene is an aromatic hydrocarbon solvent that can effectively enhance the stability of glyphosate and form a thin film on the surface of weed leaves, allowing glyphosate to continue to work and reduce the reduction in weed control effect caused by weather factors such as rainfall;

[0069] Hydroxyethyl cellulose can improve the rheological properties of the product, increase its viscosity, prevent the stratification and precipitation of herbicide components during storage, prevent the interaction between components causing adverse reactions, and extend the shelf life of the herbicide;

[0070] The antioxidant is mainly to prevent glyphosate and other ingredients from oxidizing in the air. The antioxidant is sodium sulfite;

[0071] The main function of colorants is to enhance the visual recognition of the product. In the formulation of herbicides, colorants increase the color of the product, helping users to more accurately determine the sprayed area during the spraying process to avoid confusion or missed spraying.

[0072] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
