METHOD OF APPLYING POLYANIONIC POLYMERS TO PLANTS

摘要

In a method of applying polyanionic polymers to plants, the leaves of plants, the seeds of plants or the earth adjacent plants, an effective amount of an anionic polymer is used, which comprises at least four repeat units distributed along the length of the polymer chain. The repeat units include at least one each of a maleic, itaconic, and sulfonate repeat unit.
