Abstract: The invention relates to suspension concentrates comprising a) one or more pesticides that are solid at room temperature, b) one or more specific copolymers, c) one or more additional auxiliary substances as applicable and d) one or more solvents. The copolymers b) comprise structural units of formula (I), wherein A stands for C2-C4-alkyls, B stands for a C2-C4-alkyl different from A, R stands for hydrogen or methyl, m is a number from 1 to 500, n is a number from 1 to 500, the sum of m+n is equal to 2 to 1000 and P stands for H or for a specific other concluding group, and structural units derived from specific ethylenic, unsaturated monomers that comprise an aromatic group, and structural units derived from specific ethylenic, unsaturated monomers that comprise aliphatic hydrocarbon residue. The suspension concentrates according to the invention are advantageously suitable for use as pesticides.
