Abstract
An aqueous, multiphase, stable finished formulation for crop protection active compounds is described, containing in addition to water a) 10 to 700 g/l of one or more crop protection active compounds, b) 5 to 150 g/l of one or more dispersants, c) 50 to 500 g/l of one or more wetting agents, d) 0.5 to 5 g/l of one or more thickeners and e) if appropriate an organic solvent and processes for preparation thereof are described.
