Abstract
Aqueous agricultural foam marker compositions for delineating treated from untreated areas comprise a foamable composition of an anionic surfactant which is an &agr;-olefin sulfonate and/or an alkyl ether sulfate, a linear C12-16 alkanol, a foam stabilizing polymer, and one or more solvents. The foams produced from the foamable compositions have increased foam life, enhanced wind resistance, and are producable over a wide range of soft/hard water conditions.
