Abstract
A method for reducing loss of water from the leaves and stems of plants by transpiration and for protecting plants from damage by wind and cold consists of applying to the leaves and stems a transpiration-decreasing composition consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic polymer, a cross-linking agent for the carboxylated hydrophilic polymer and an effective amount of an ultravioletabsorbing agent.

Composition for decreasing the loss of water from leaves and stems of plants by transpiration and for protecting plants from damage by wind and cold consisting essentially of an aqueous solution or dispersion of a carboxylated hydrophilic acrylic polymer, a cross-linking agent for the carboxylated hydrophilic acrylic polymer and an effective amount of an ultraviolet-absorbing agent, wherein the carboxylated hydrophilic acrylic polymer and the cross-linking agent together comprise from about 3% to about 30% by weight of the aqueous solution or dispersion, said carboxylated hydrophilic acrylic polymer is a copolymer containing monomer units from at least one C.sub.1 -C.sub.4 alkyl acrylate or methacrylate and from about 5% to about 20% by weight of at least one carboxylic monomer, and the amount of cross-linking agent is about 1% to about 20% by weight of solids of said carboxylated hydrophilic acrylic polymer.
