Abstract: The invention relates to a process for the production of granulated seed comprising seed kernels which are coated with a coating layer, the process comprising the following steps: providing seed kernels, applying a binder to the seed kernels, giving rise to seed kernels coated with a binder, and applying a coating composition comprising silica to the seed kernels coated with binder, giving rise to seed kernels coated with a coating layer. The invention furthermore relates to the use of silica as component of the coating layer of granulated seed for improving the germination ability of the seed. The invention furthermore relates to granulated seed, comprising seed kernels coated with a coating layer, characterized in that the coating layer comprises silica and that the silica is distributed within the entire coating layer.

Abstract: Dispersion containing, in addition to water, 0.5 to 20 wt. % of hydrophobic silica, 0.01 to 10 wt. % of a gelling or viscosity-increasing additive, 0.1 to 1 wt. % of a preservative and 0 to 1 wt. % of a surface-active substance. It is prepared by a procedure in which the individual components are dispersed successively or together into the water and in this procedure the individual components are deaerated before and/or during the addition or the dispersion is deaerated during the individual dispersing steps. The dispersion can be employed as an insecticide.

Abstract: Dispersion comprising hydrophobic pyrogenically prepared silicon dioxide, alcohol and at least one additive which promotes the dispersion and, as additional component, at least one insecticide and/or acaricide. The dispersion can be canned in spray cans and used as insecticide.

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 which, as further components, contains at least one phenol or at least one phenol derivative and/or at least one aldehyde. It is prepared by dispersing the individual components successively or together in water, in which case the individual components are deaerated before and/or during the addition or the dispersion is deaerated during the individual dispersion steps and thereafter the residual air present in the dispersion is removed by application of vacuum. The dispersion can be used as insecticide and for controlling pathogenic agents.
