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.
Claims12
A non-aqueous, emulsifiable concentrate (EC )formulation for pesticidal crop protection active compounds which comprises
- 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.
A formulation consisting essentially of
- 100 to 850 g/L of at leastone pesticidal crop protection active compound,
- 100 to 300 g/L of a solvent selected from the group consisting of diethylenglycol dialkylethers, aromatic hydrocarbons, aliphatic hydrocarbons and esters of plant oils or mixtures thereof,
- 0 to 250 g/L of the cosolvent selected from the group consisting of N-methylpyrrolidone, y-butyrolactone, cyclohexanone and benzyl alcohol,
- 40 to 400 g/L of the emulsifying surfactant system being a mixture of anionic and non-ionic surfactants,
- 0.1 to 10 g/L of at least one perfluoro-(C6-18)-alkylphosphonic acids and/or perfluoro-(C6-18)-alkylphosphinic acids, and
- optionally a stabilising agent and/or antioxidant.
