A method is disclosed for increasing the resistance of plants to damage by non-freezing dehydrating conditions comprising treating the plants with an aqueous medium containing a nonionic surface active polyethoxylated polyoxypropylene block copolymer of about 2,000 to 9,000 average molecular weight, and optionally urea and/or a UV absorber, and/or finely ground, readily dispersible zinc oxide, aluminum oxide or titanium dioxide reflecting agent, and compositions for use in such method.
