I. Core Function: Improving Pesticide Utilization and Breaking Through Traditional Application Bottlenecks
Organic silicone reduces the surface tension of pesticide solutions to 21.0-24.0 mN/m, significantly enhancing their wettability and spreadability on plant leaves and pest surfaces. Its "T-shaped umbrella" molecular structure increases the pesticide's coverage area by over 10 times, ensuring uniform adhesion even on leaves with waxy layers or hairs. For example, when controlling rice leaf rollers, adding 0.05% of organosilicon adjuvant reduces water usage per mu from 45 kg to 15 kg, while still allowing the pesticide to penetrate hidden areas, improving insecticide efficacy by over 30%.
In addition, organosilicon promotes the stomata penetration of systemic pesticides, increasing their absorption rate by 50%. It also resists rain washout, eliminating the need for re-spraying after rain. Experimental data shows that herbicides containing organosilicon retain over 85% of their effectiveness after rainfall, while traditional herbicides only retain 40%.
II. Comprehensive Benefits: A Win-Win for Cost Reduction, Efficiency Improvement, and Ecological Protection
Economically: Organosilicon can reduce pesticide use by over 30% and water consumption by 50%. For weed control in wheat fields, for example, the cost of herbicides per mu (approximately 25 yuan) has been reduced to 15 yuan, while also saving labor and water resources. When combined with pesticides, fungicides, foliar fertilizers, and other agricultural chemicals, the dosage required is only 0.015% to 0.1%, yet it can extend the duration of efficacy by 2-3 days.
Ecologically: By reducing pesticide runoff, organosilicon reduces the risk of groundwater contamination. Its extremely low physiological toxicity makes it safe for crops, making it particularly suitable for sensitive crops such as leafy vegetables. In citrus cultivation, a gibberellin solution containing organosilicon can extend the fruit harvest period by 15 days, improve the fruit surface finish by two grades, and reduce the risk of pesticide residues.
Technical Compatibility: Silicones are suitable for all pesticide formulations, including emulsifiable concentrates, emulsions in water, and microemulsions, and exhibit excellent compatibility with mainstream pesticides such as glyphosate and emamectin benzoate. Their synergistic effect is even more pronounced when used with fine nozzles, low-flow, high-pressure sprayers, further reducing pesticide drift.
