Plant growth regulator compositions comprise an aqueous mixture of one or more plant growth regulators and one or more polyanionic polymers. The polymers contain at least about 80 mol percent of repeat units bearing at least one anionic functional group, the plant growth regulator being present at a level of up to about 6000 ppm. Preferably, the polymers contain respective amounts of maleic and itaconic repeat units. |
