Agrochemical suspension concentrates, particularly in aqueous or liquid oil based medium, comprise solid particles including one or more agrochemical active components; and a dispersing agent including a water soluble or dispersible styrene (meth)acrylic acid copolymer. In particular the styrene (meth)acrylic acid copolymer has a molar ratio of residues of (meth)acrylic acid monomer(s) to styrene monomer(s) from 20:1 to 1:5, particularly from 3: 1 to 1:1. The formulation will usually also contain wetting agents; and/or adjuvants. The agrochemical active can be plant growth regulators, herbicide s, and/or pesticides, for example insecticides, fungicides, acaricides, nematocides, miticides, rodenticides, bactericides, molluscicides and bird repellants. The suspension formulations will typically be used diluted in water and sprayed onto plants or the soil surrounding the plants.
