  • Publication number: 20060030486
    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.

  • Publication number: 20050148709
    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.

  • Publication number: 20050085391
    Abstract: The invention relates to aqueous plant protection formulations comprising water-soluble pesticides, agrochemical salts and polymers based on acrylamidopropylmethylenesulfonic acid (AMPS) and “macromonomers”. The formulations show high solubility of the pesticides and of the agrochemical salts, and excellent stability on storage. The addition of the polymers improves the compatibility and solubility in water of the pesticides and agrochemical salts. Salting-out effects are suppressed or minimized. The formulations are preferably concentrated formulations, preferably soluble liquids (SL) and soluble concentrates.
