Abstract

The invention relates to solid active substance formula-tions which contain wetting agents in combination with a surfactant (antifoam) from the group comprising per-fluoroalkylphosphinic acid/perfluoroalkylphosphonic acids or their salts. The invention also relates to the use of these formulations, in particular in the preparation of spray slurries.
