Abstract

Dispersion comprising, in addition to water, from 0.5 to 20% by weight of hydrophobic silica, 0.01 to 10% by weight of a gelling or viscosity-increasing additive, 0.1 to 1% by weight of a preservative and 0 to 1% by weight of a surface-active agent, which comprises, as additional component, at least one insecticide and/or acaricide. It is prepared by dispersing the individual components, successively or together, in the water and, in this connection, deaerating the individual components before and/or during the addition or deaerating the dispersion during the individual dispersing stages. The dispersion can be used as insecticide or acaricide.
