Abstract
The systemic activity of systemic active ingredients in sprayed foliar systemic compositions is improved by incorporating water soluble polyacrylamide in the sprayed composition. The polyacrylamide can have a molecular weight sufficiently low that its presence does not substantially affect the spray pattern of the composition, and the polyacrylamide can have low solution viscosity such that a convenient concentrate can comprise an aqueous solution of the active ingredient and the polymer. Alternatively, the polymer can be supplied as a powder or as a reverse phase emulsion or dispersion. The sprayable composition is preferably formulated such that the spray droplets have a small particle size.
