The most promising allelopathic weeds are hawkweeds (Hieracium spp.). They are effective in reducing other asteraceous weeds (Murphy and Aarssen 1995b) and yellow hawkweed (H. pratense Tausch.) inhibited Canada thistle (Cirsium arvense (L.) Scop.), perennial sow-thistle (Sonchus arvensis L.), yarrow (Achillea millefolium L.), and annual sow thistle (Sonchus oleraceus L.) however, the long-term effect on perennial species is unclear (Murphy 2001).
