Vyred is a product whose function is to acidify, up to optimal pH values, the water to be used in fertigation and/or for foliar treatments, providing the crops with nitrogen and phosphorus. The product Vyred lowers the pH when mixed with water and other products making the active molecules spread over plants are more effective. Vyred also increases the solubility of the other products blended with it making the solution more adhesive and more homogenous. Besides, obstructions in the pipeline system are definitively reduced. Using Vyred, the surface tension of the solution lowers. Consequently the solution will be better uptaken by plant via stomata and via cuticle and carried within the plant tissues. Eventually, Vyred washes out the honeydew and acts as emulsifier.
