The drifting tendency of agricultural chemical spraying liquids, particularly aqueous spraying liquids, is reduced by adding thereto as a foaming agent an amine salt of a p-alkylbenzenesulfonic acid of the general formula <IMAGE> (I) in which R is alkyl of from 8 to 16 carbon atoms, R1 and R2 (which may be the same or different) are hydrogen, alkyl, or hydroxyalkyl of from 1 to 6 carbon atoms, and R3 is alkyl or hydroxyalkyl of from 1 to 6 carbon atoms.
