Abstract

When herbicides are applied, surfactants can affect the wettability of leaves of the plants and the effectiveness of the herbicides. According to the invention, a particular intensification of action is achieved when surfactants from the group comprising the C.sub.10 -C.sub.18 -alkyl polyglycol ether sulfates and their physiologically acceptable salts together with leaf-acting selective herbicides or the leaf-acting non-selective herbicides glyphosate, paraquat or diquat are applied.
