一般影響
賴特(1997)報告說：當維修路基時，使用來自感染區的砂石，其中可能就有一些款冬花的根莖，此時款冬花就開始在新的棲地拓展。款冬花對路邊雜草的競爭力似乎很強，並且不怕常用於路邊的雜草除草劑。最終，一小塊感染可能擴大蔓延穿越圍欄到鄰近的農場。農耕操作會使此雜草傳播到整個田地。風也會把種子吹到新的小塊棲地，如果沒有對種子發芽的地方噴灑除草劑，它會開始在新的棲地生長。在農地裡，款冬花(Tussilago farfara)已被報告生長在玉米田，大豆田，冬麥田，春麥田和苜蓿的植群。一旦力族群，款冬似乎很能和這些作物的競爭。如果不加以控制，款冬可以在短時間內佔滿田地。
地點特有的影響：Canada 
棲地改變: If not controlled, T. farfara can in time take over a field" (Wright, 1997).
競爭: T. farfara seems to compete strongly with the roadside grasses, and is not controlled by commonly used roadside herbicides (Wright, 1997).
農業: In field crops, T. farfara has been reported in corn, soybeans, winter wheat, spring grain and alfalfa stands. Once well-established, T. farfara appears to hold its own against competition from these crops (Wright, 1997). United States (USA)
