In densely standing, fully grown two-year fodder stands the annual seed weeds find no room for development — though they do in gappy ones. With repeated mowing even these pose no serious threat. Fodder-field cultivation is above all a proven means of gaining the upper hand over the otherwise hard-to-master perennial problem weeds such as creeping thistle (Cirsium arvense) and curly dock (Rumex crispus). The creeping thistle is already weakened by the first cut, more so still by the second or even third. After two years of use in this manner, it becomes possible to keep the field largely thistle-free for the following crop — usually a winter cereal. With regard to the dock, which is weakened after each mowing but then rapidly shoots to seed, a reduced seed production is usually unavoidable. As for couch grass (Agropyron repens), repeated cutting impairs the vigour of the rhizomes and thereby their further spread.
