Seisil is a product that combines the antagonistic effects of the polymerized silicic acid with the activation of the physiological response of the crop. Seisil acts as a liquid crystal generating a protective film of silica that is deposited under the cell walls of leaves and fruits. This action also protects the plant tissues to avoid direct contact with water in case of light rain or dew. Furthermore, Seisil confers structural stability to cells increasing their resistance and acts activating a series of genes that stimulate the plant’s defense system.
