The systemic activity of systemic active ingredients in sprayed foliar systemic compositions is improved by incorporating water soluble polymer. The polymer can have a molecular weight sufficiently low that its presence does not substantially affect the spray pattern of the composition and such that the polymer can initially be supplied as an aqueous solution having 1 to 25% concentration. When the active ingredient is water soluble, for instance glyphosate or chlormequat, a concentrate can comprise an aqueous solution of the active ingredient and the polymer. |
