  • Publication number: 20210187479
    Abstract: In an improved superabsorbent complexed with aluminum ions, the aluminum ions are applied in the form of an aqueous solution comprising aluminum ions, which has the feature that it comprises aluminum ions in a proportion within the range of 0.5%-15% by weight (converted if appropriate to Al3+), based on the total mass of the solution, and further comprises anions of lactic acid (lactate ions) and phosphoric acid (phosphate ions), where the molar proportion of the lactate ions is within the range of 0.01-2.99 times the molar amount of Al3+ and the molar proportion of the phosphate ions is within the range of 0.01-2.99 times the molar amount of Al3+.

  • Patent number: 9700048
    Abstract: The present invention provides a composition comprising a pesticide and a copolymer, which contains in polymerized form a N-vinyllactam (monomer A); an acrylamide (monomer B) selected from N—C1-C6-alkyl acrylamide and N,N-di-C1-C6-alkyl acrylamide; and a C1-C4-alkyl (meth)acrylate (monomer C). Further on, it provides a process for preparing said composition by contacting the pesticide and the copolymer; a method for controlling phytopathogenic fungi and/or unwanted plant growth and/or unwanted insect or mite infestation and/or for regulating the growth of plants, wherein said composition is caused to act on the respective pests, their habitat or the plants to be protected from the respective pest, to the soil and/or to unwanted plants and/or the crop plants and/or their habitat; and a plant propagation material comprising said composition.
