In agricultural production, the effective deposition and spread of pesticide spray droplets on the leaf surface of crops is a key factor determining the efficacy of pest control. However, most crop leaves are covered with a waxy layer, resulting in extremely low surface energy. Traditional spray droplets are difficult to effectively wet and spread on such surfaces. Our company's product, agricultural organic silicon surfactant 2000, as a special agricultural organic silicon additive modified with ethoxy groups, with its extremely low surface tension, excellent spreading and penetration properties, demonstrates significant application value in areas such as herbicides, insecticides, fungicides, foliar nutrient agents, and growth regulators, providing an efficient additive solution for reducing pesticide use and enhancing efficacy, as well as for precise application.


I. Core Physical and Chemical Properties of the Product


Agricultural organic silicon surfactant 2000 is a colorless to light yellow transparent liquid with a specific gravity of 0.020 at 25 degrees Celsius. Its viscosity ranges from 20 to 40 centipoises, its refractive index is 1.4430, and the cloud point of the 0.1% aqueous solution is 40 degrees Celsius. It is transparent to semi-transparent in water solubility, with a surface tension as low as 21.5 millinewtons per meter, and the content of the active ingredient is above 99%. This product is a polyether modified heptamethyl siloxane structure, providing strong spreading driving force through the siloxane backbone, and the polyether chain segments provide water solubility, belonging to organic silicon non-ionic surfactants. Its extremely low surface tension enables it to reduce the surface tension of water from 72 millinewtons per meter to around 21.5 millinewtons per meter at an extremely low addition amount.


II. Core Performance Advantages


Agricultural organic silicon surfactant 2000 demonstrates the following core performance advantages in agricultural spraying applications:


Superior spreading and rapid wetting performance. The product can significantly reduce the surface tension of the solution, decrease the contact angle between the droplet and the leaf surface, enhance the wetting, adhesion, and spreading ability of the pesticide on the plant surface or the body surface of pests, and achieve rapid spreading and uniform coverage on the leaf surface.


Strong penetration and synergistic performance. The product can carry the active ingredients through the plant leaf wax layer and epidermal tissue, promoting the absorption and conduction of the pesticide, thereby enhancing the efficacy of the pesticide, without decomposing the original drug.


Extremely low plant toxicity. The product has lower plant toxicity than common fatty amines, ethoxy alcohols, etc., providing higher crop safety and lower risk of pesticide damage.


Emulsification dispersion and compatibility with formulations. The product has excellent emulsification dispersion performance and good compatibility with various pesticide raw materials and additives, and can be directly added to the formulation or used as a ready-mixed bucket mixer additive.


III. Wide Application Areas


Agricultural organic silicon surfactant 2000, with its outstanding performance, can play a key role in the following agricultural application areas, including:


1. Synergistic application of herbicides. As a spray improvement agent and foliar absorption enhancer, it can be used with herbicides to significantly improve the spreading and adhesion performance of the pesticide on weed leaves, enhancing the control effect on stubborn weeds and reducing the dosage. Suitable for glyphosate, paraquat, and other systemic herbicides and selective herbicides for bucket mixing synergistic enhancement.


2. Synergistic application of insecticides. The product can enhance the wetting, adhesion, and spreading ability of the pesticide on the plant leaves and the body surface of pests, improving the efficacy of the pesticide, and reducing pesticide usage. Suitable for aphids, whiteflies, lepidopteran larvae, etc.


3. Synergistic application of fungicides. The product can improve the uniformity of coverage and penetration of the fungicide on the leaf surface, enhancing the disease control effect.


4. Synergistic application of foliar fertilizers and growth regulators. The product can enhance the adhesion and penetration absorption efficiency of foliar fertilizers and plant growth regulators on the leaf surface, improving nutrient utilization and regulation effects.


IV. Usage Suggestions and Recommended Dosages When the agricultural organic silicon surfactant 2000 is used as a ready-mixed and ready-to-use bucket mixer additive, the dosage ranges from 0.02% to 0.04%, which means 3 to 6 grams should be added to a 15-kilogram sprayer. In the pesticide formulation recipe, the dosage ranges from 0.5% to 5%. The product can be directly added to the formulation recipe for pesticide production or used as a ready-mixed and ready-to-use bucket mixer additive.


V. Packaging Specifications and Storage Conditions


The agricultural organic silicon surfactant 2000 is packaged in 25-kilogram, 50-kilogram plastic drums or 200-kilogram iron drums. This product is non-hazardous. During storage and transportation, attention should be paid to moisture prevention and the prevention of the admixture of various impurities. Under sealed and room temperature conditions, the shelf life is two years.


VI. Quality Assurance and Industry Application Value


During the production process of the agricultural organic silicon surfactant 2000, a strict quality control system has been established. Key indicators such as product appearance, specific gravity, viscosity, refractive index, cloud point, and active ingredients are tested throughout the process to ensure consistency and reliability between batches.


With the continuous advancement of the national policy of reducing pesticide use and increasing efficiency and the popularization of precise application techniques, the demand for agricultural organic silicon additives with super spreading, efficient penetration, and low plant toxicity continues to grow. The agricultural organic silicon surfactant 2000, with its extremely low surface tension, outstanding spreading and penetration performance, and good crop safety, is becoming an important additive option in pesticide formulations and aerial spraying operations, providing strong support for promoting the green and high-quality development of agriculture and reducing pesticide use.
