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 C 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.

Agricultural foam marker compositions and use thereof

Aqueous agricultural foam marker compositions for delineating treated from untreated areas comprise foamable compositions of an anionic surfactant which is an &bgr;-olefin sulfonate, an alkyl or alkyl-ether sulfate, a long chain alkylbenzene sulfonate or a sulfosuccinate; a linear C or C alkanol or mixtures thereof; one or more solvents; and optionally a foam stabilizing polymer. The foam produced from the compositions have increased foam life, a pour point of 10&deg; C. or lower, and are producable over a wide range of soft/hard water conditions.
