一般影响
赖特(1997)报告说:当维修路基时,使用来自感染区的砂石,其中可能就有一些款冬花的根茎,此时款冬花就开始在新的栖地拓展。款冬花对路边杂草的竞争力似乎很强,并且不怕常用于路边的杂草除草剂。最终,一小块感染可能扩大蔓延穿越围栏到邻近的农场。农耕操作会使此杂草传播到整个田地。风也会把种子吹到新的小块栖地,如果没有对种子发芽的地方喷洒除草剂,它会开始在新的栖地生长。在农地里,款冬花(Tussilago farfara)已被报告生长在玉米田,大豆田,冬麦田,春麦田和苜蓿的植群。一旦力族群,款冬似乎很能和这些作物的竞争。如果不加以控制,款冬可以在短时间内占满田地。
地点特有的影响:Canada 农业: 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). 栖地改变: If not controlled, T. farfara can in time take over a field" (Wright, 1997). 竞争: T. farfara seems to compete strongly with the roadside grasses, and is not controlled by commonly used roadside herbicides (Wright, 1997).
