Title: Wetting agent and use thereof in agriculture

Abstract: An easily sprayable aqueous composition for stimulating the root development of plants comprises a surface-tension lowering surfactant, an organic liquid solvent; a foam-suppressing agent; and carboxyvinyl polymer with a carboxylic acid equivalent weight above 90. Improved plant growth stimulation is observed when the composition includes a combination of carboxyvinyl polymers of differing equivalent weights. The composition may be applied directly to plant seeds or to plants or the soil surrounding plants by conventional means. The composition may be applied alone or in combination with pesticides, herbicides, fertilizers, irrigation water, and the like.
