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 agochemical active can be plant
growth regulators, herbicides, 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.
