Abstract

The invention relates to preparations, in particular plant-protective preparations which contain a mixture of at least two different active plant-protective substances, wherein a) at least one active substance is selected from a conazole group (active substance 1) and b) another active-plant protective substance (active substance 2) whose water solubility at a temperature of 20° C. is less than 20 g/l., c) at least one type of copolymer CP consisting of M monomers comprising α) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group and β) at least one type of neutral monoethylenically unsaturated monomer M2, wherein the quantitative ratio between the active substance 1 and the other active plant-protective substance 2 ranges from 1:10 to 10:1. Said invention also relates to novel copolymers CP which are embodied in the form of polymers consisting of at least three types of different monoethylenically unsaturated monomers M and comprise, in the polymerization incorporated form, α) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group, β1) at least one type of neutral monoethylenically unsaturated monomer M2 whose water solubility at a temperature of 20° C. is less than 30 g/l and β2) at least one type of neutral monoethylenically unsaturated monomer M2b whose water solubility at a temperature of 20° C. is greater than 50 g/l.
