The application of silicone polyether silicone oil in the agricultural field mainly relies on its unique molecular structure and excellent performance characteristics, and has become a key additive to improve the effectiveness of agricultural chemicals such as pesticides and fertilizers.Its core component, polyether-modified polydimethylsiloxane, reduces the surface tension of water to below 21mN/m through a T-shaped umbrella structure, which significantly enhances the wettability and permeability of the liquid on the surface of plant leaves and pests.


In terms of pesticide synergistic effects, this material can be used in combination with insecticides, fungicides, herbicides, etc.For example, in the prevention and control of rice longitudinal leaf borer, adding 0.05% silicone additives can reduce the water consumption per acre from 45 kg to 15 kg. At the same time, the liquid medicine can penetrate the waxy protective layer woven by the pest to achieve the "louse in the urn" touch-killing effect.For concealed pests such as small vegetable moths, its super spreading properties can penetrate the liquid into the inside of the leaves and reduce pesticide residues in vegetables.In the application of herbicides, when combined with water-based herbicides to remove broad-leaved weeds, the liquid can quickly penetrate into plant tissues to form "rain resistance" and avoid repeated spraying during the rainy season.


In the field of fertilizer efficiency enhancement, this material is used as a foliar fertilizer additive to promote the absorption of nutrients such as nitrogen, phosphorus, and potassium through the pores.Experimental data show that adding 0.025%-0.05% silicone additives can increase the absorption efficiency of foliar fertilizer by 30%-50%, especially suitable for the spray system of trace elements and biological pesticides.Its rainwater-resistant characteristics can reduce fertilizer loss and ensure crop nutrient supply during the rainy season.


In the application of agricultural facilities, this material can be used as an internal additive for the drip-free film of plastic greenhouses to prevent condensation of water mist by reducing the surface tension, increasing the light transmittance by 15%-20%, and inhibiting the growth of mold.In terms of saline-alkaline land improvement, its hydrophilic characteristics contribute to the formation of soil pellet structure. When used with silicone functional fertilizers, the pH value of severely saline-alkaline land can be reduced from above 10 to 7-8, significantly improving the quality of cultivated land.


In practical applications, attention should be paid to the principle of ready-to-use. It is recommended to use a low-flow high-pressure sprayer with a fine nozzle, and the water consumption per acre can be controlled at 5-20 kg.Stability testing is required in acidic or alkaline formulas to avoid mixing with strong oxidants.By reducing the amount of pesticides by 30%-50% and reducing water consumption by more than 50%, the material effectively reduces the risk of agricultural surface-source pollution while ensuring the prevention effect.
