Abstract: The invention relates to the use of polymers based on acrylamidopropylmethylenesulfonic acid (AMPS) and macromonomers as crystallization inhibitor for plant protection formulations. The polymers inhibit crystallization of the pesticidal active substances (herbicides, insecticides, fungicides, acaricides, bactericides, molluscicides, nematicides and rodenticides) present in the plant protection formulations. The use in the case of emulsifiable concentrates (EC) and suspension concentrates (SC) is particularly advantageous.

Abstract: The invention relates to solid plant protection formulations comprising polymers based on acrylamidopropylmethylenesulfonic acid (AMPS) and “macromonomers”. The formulations are dispersible without a great stirring effort. In addition, the formulations have excellent stability on storage with regard to temperature variations and humidity (e.g., no caking). The invention is suitable in particular for wettable powders (WP) and water dispersible granules (WDG). The suspensions prepared from the solid formulations show a markedly increased suspensibility (ability to remain suspended) and stability.

The concentrates can, for example, be used for the preparation of cosmetic, pharmaceutical and dermatological preparations.
