With the large-scale development of modern agriculture, agrochemicals including insecticides, fungicides, fertilizers and plant growth regulators are widely used. Most pesticide formulations are incorporated with functional additives to improve adhesion, permeability and emulsification. A large number of white foam is easily generated during water dilution, stirring and mixing. The foam features long retention time and slow defoaming rate, which has long troubled agricultural operators. Due to the lack of professional knowledge about formulation, blind stirring and arbitrarily add agrochemicals, which further aggravates foaming problems. This also will cause a series of issues such as agrochemicals waste, inconsistent solution ratios, spray equipment malfunctions and decrease agrochemical control efficacy.

To solve the foaming problem, the adoption of low-foam silicone synergists has become a feasible and easily solution, farmers can directly use low-foam organosilicon adjuvant instead of conventional organosilicon adjuvant.

Topwin has developed an efficient silicone adjuvant SW-255, adopts a optimized molecular structure to balance low-foam property and excellent wettability. It provides an innovative solution with high efficiency and stability for agrochemical application, aerial spraying and environmentally friendly agricultural production.

The core advantages of SW-255 is from its precise molecular regulation, and presents outstanding technical parameters in key performances.

1. Ultra-low surface tension: surface tension of aqueous solution≤ 21.5 mN/m. This product can rapidly reduce the surface tension of agrochemical liquid and achieve comprehensive wetting on waxy leaves and crop gaps. Its wetting performance is reached at Level 5, and it completes the standard wetting test within 2 seconds, providing a reliable foundation for the uniform adhesion of agrochemicals.

       2.Excellent foam-inhibition properties: The initial foam volume is merely 120 mL, which decreases to 106 mL after five minutes. Theq foam data are far lower than those of similar conventional products. This product can solve the common drawbacks of traditional auxiliaries, such as easily foaming and spray uniformity. Additionally, it is suitable for aerial vehicle (UAV) aerial spraying and field crop spraying.

       3.Excellent compatibility and stability: It is applicable within a pH range of 6–8 and shows good compatibility with most agrochemical formulations. With outstanding water solubility, it can be directly used as tank mixing without extra formulation adjustments.

Compared with other products in the same series, SW-248 and SW-253, SW-255 has achieved better optimization in wettability, foam-inhibition, and unstable foam control. It provides a particularly significant advantage in low-foam property, meets the dual requirements of high-efficiency synergism and application stability.

Meanwhile, SW-255 adopts an eco-friendly formulation free of harmful substances such as APEO and heavy metals, complying with EU REACH regulations and relevant domestic environmental standards. It contributes to the sustainable development of green agriculture. Topwin will continue to focus on the practical needs of agrochemicals production, launch more silicone adjuvants that balance high efficiency and environmental performance, promote agricultural efficiency, increase farmers’ incomes, and advance the development of green agriculture.
