Abstract
The novel emulsifiable concentrate (EC) formulation comprising at least one pesticidal crop protection active compound, at least one non-polar organic solvent, optionally, at least one polar aprotic cosolvent, an emulsifying surfactant system enabling an oil-in-water emulsion to be formed when the formulation is added to water, and at least one defoaming or foam breaking agent selected from the group consisting of perfluoroalkylphosphonic acids, perfluoroalkylphosphinic acids and perfluoroaliphatic polymeric esters is useful for combating pests or diseases caused by pests at a locus by treating the locus with a composition obtained from emulsifying the EC in water.
