Abstract
The present invention relates to stabilized, concentrated or diluted emulsions of the oil-in-water (O/W) type exhibiting a pesticidal activity and to a process for making use of the emulsions. More specifically the invention relates to stable O/W macroemulsions which comprise one or more pesticidal active ingredients in the oil phase or additionally, macroemulsions which comprise one or more pesticidal active ingredients in both the oil and water phases, wherein the oily phase is emulsified or dispersed in the water phase by an emulsifying system; and wherein the emulsions are further stabilized by a solid dispersing agent, namely titanium dioxide, which maintains or improves the emulsion stability. It also relates to a suspoemulsion obtained by milling the said emulsion with an additional solid pesticidal substance.
