In the intricate world of crop protection, the physical properties of pesticide sprays play a decisive role in their efficacy. NINGBO INNO PHARMCHEM CO.,LTD. specializes in developing chemical additives that optimize these properties, with their Wetting Dispersant RU208 being a prime example. This advanced non-ionic silicone surfactant is engineered to dramatically improve how pesticides spread and are absorbed by plants.

The fundamental challenge in pesticide application is often the surface tension of water-based sprays. This inherent property causes droplets to maintain a spherical shape, limiting their ability to spread across leaf surfaces. Consequently, coverage can be patchy, leading to incomplete pest or disease control. RU208, a powerful wetting dispersant from NINGBO INNO PHARMCHEM CO.,LTD., tackles this issue head-on by rapidly reducing surface tension. At a mere 0.1% concentration, it can lower the surface tension of water to an exceptionally low 20.5 mN/m, a key metric for superior spreading.

This dramatic reduction in surface tension directly influences the contact angle between the spray liquid and the plant leaf. A lower contact angle means the liquid spreads out rather than beading up, creating a thin, uniform film across the leaf surface. This enhanced spreading is critical for ensuring that the pesticide covers all areas requiring protection, thereby improving the overall efficiency of the treatment. NINGBO INNO PHARMCHEM CO.,LTD. emphasizes that maximizing coverage is a core benefit of using RU208.

Beyond improved spreading, the excellent wetting properties of RU208 also facilitate the absorption of pesticide active ingredients into the plant. Many pesticides are systemic, meaning they need to be absorbed through the leaf and transported within the plant to be effective. The surfactant helps to break down the barriers of the leaf cuticle, allowing for more efficient uptake of the pesticide. This promotes faster action and greater efficacy. NINGBO INNO PHARMCHEM CO.,LTD. highlights that promoting pesticide absorption is a key advantage of their product.

Another significant advantage is the improved rainfastness. Pesticides that are well-spread and absorbed are less likely to be washed off by rain. The improved adhesion to the leaf surface and penetration into plant tissues means that the protection provided by the pesticide remains robust even after rainfall. This increased resistance to rain erosion ensures that the crop protection investment is more durable. NINGBO INNO PHARMCHEM CO.,LTD. points out this crucial benefit for agricultural applications.

RU208 offers flexibility in its application. It can be used as a tank-mix adjuvant, added to the pesticide spray mixture, or integrated into the pesticide formulation during its production. NINGBO INNO PHARMCHEM CO.,LTD. recommends low dosages for tank-mixing (0.01-0.1%) and provides guidance for formulation use (0.1-5%), stressing the importance of pH control for optimal performance.

In essence, the RU208 Wetting Dispersant from NINGBO INNO PHARMCHEM CO.,LTD. is an indispensable tool for enhancing pesticide performance. By leveraging the power of silicone surfactants to reduce surface tension, it ensures better coverage, promotes absorption, and increases rainfastness, ultimately contributing to more effective and resilient crop protection strategies.
