Performance and use
performance:Agricultural silicone additive is a low molecular weight silicone polyether nonionic surfactant used to improve the wetting, dispersing and penetrating properties of pesticides, especially aqueous broadleaf herbicides, insecticides and plant growth regulators. Performance.

Uses: Significantly reduce the surface tension of aqueous pesticide mixtures to levels far below those achieved with traditional nonionic surfactants. At a low concentration of 0.01%, the surface tension can be reduced to 23 dynes/cm or less, and extremely fast wetting and dispersing on
surfaces that are difficult to wet such as foliar waxy layers, thereby allowing herbicides and insecticides , complete coverage of fungicides and other pesticides. In addition to rapid wetting and dispersion, super wetting agents can greatly increase the uptake of pesticides by plant tissues. The addition of a wetting agent in the herbicide tank mixing can significantly improve the wetting efficiency, especially in the application of water-soluble herbicides in broadleaf control. Rapid intake can produce “rainfastness” – because the herbicide has penetrated into the plant’s internal tissues, it will not be washed away by rain。
For direct addition in pesticide formulations, the components can be added directly as a formulation. It is stable in neutral aqueous formulation (pH=7), but degrades rapidly in acidic or alkaline formulations. Super wetting agents can be mixed before use to improve the biological properties of the spray. It can be added to the pesticide formula or to the tank spray. Add pesticide formula: It is recommended to add 0.5-8% of the pesticide stock solution. It is recommended to adjust the pH of the pesticide formula to 6-8.Add to the tank spray method: Usually add 50 grams of H-77 (4000 times) per 200 kg of spray. Under normal circumstances, different application fields and corresponding addition parameters are as follows: plant growth regulator 0.025-0.05%; herbicide 0.025-0.15%; insecticide 0.025-0.1%; fungicide 0.015-0.05%; fertilizer and trace The amount of the element is 0.015-0.1%.
