General Impact
Wright (1997) states that, "when gravel from infested pits is used in roadbed maintenance, some rhizomes of Tussilago farfara survive, and start up new Tussilago farfara patches. Tussilago farfara seems to compete strongly with the roadside grasses and is not controlled by commonly used roadside herbicides. Eventually the patch may expand to creep under the fence and into an adjoining cultivated field. Tillage operations can then spread the weed throughout the field. Seed blown by the wind may also start new patches, depending on the herbicide programme being used on the field where the seed germinates. In field crops, Tussilago farfara has been reported in corn, soybeans, winter wheat, spring grain and alfalfa stands. Once well-established, Tussilago farfara appears to hold its own against competition from these crops. If not controlled, Tussilago farfara can, in time, take over a field."
