  • Publication number: 20110245082
    Abstract: The present invention relates to a use of a graft copolymer obtainable by free-radical polymerization of a monomer mixture comprising N-vinyllactam, vinyl ester, and a polyether for increasing the activity of a pesticide. The invention also relates to a composition comprising a pesticide and a graft copolymer obtainable by free-radical polymerization of a monomer mixture comprising i) 30 to 80% by weight of N-vinylpyrrolidone, N-vinylcaprolactam or mixtures thereof, ii) 10 to 50% by weight of vinyl acetate, and iii) 10 to 50% by weight of a polyether. It further relates to a method for preparing said composition by mixing the pesticide and the graft copolymer and to a method for controlling phytopathogenic fungi and/or undesired plant growth and/or undesired attack by insects or mites and/or for regulating the growth of plants.
