Abstract

Dispersion containing, in addition to water, 0.5 to 20% by weight of hydrophobic silica, 0.01 to 10% by weight of a gelling additive, or viscosity-increasing additive, 0.1 to 1% by weight of a preservative, 0 to 1% by weight of a surface -active substance, which, as further component, contains organic insecticides. It is produced by dispersing the individual components successively or together into the water and in this process deaerating the individual components before and/or during the addition or deaerating the dispersion during the individual dispersion steps. The dispersion can be used as insecticide.
