Abstract
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 C14 or C16 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° C. or lower, and are producable over a wide range of soft/hard water conditions.
