ABSTRACT:
A novel arthropodicidally-active composition-of-matter is disclosed. Such a composition-of-matter comprises an aqueous lower alkanol solvent, and a toxicant as well as an emulsifier, both contained within the solvent. The amount of emulsifier, relative to the amount of solvent, is effective for forming a foam matrix that is able to collapse after a predetermined period of time thereby to form an arthropodicidally-active film. Also disclosed are methods for producing such an arthropodicidally-active film.
