General Impact
Linaria vulgaris can suppress native grasses and compete for soil water resources reducing biodiversity (ANHP, 2006). It also replaces valuable forbs in range and pasture land reducing the efficiency of livestock grazing; livestock do not prefer the taste of yellow toadflax and it is moderately toxic (ANHP, 2006). Yellow toadflax can also be an alternate host for several plant diseases, namely cucumber mosaic virus and broad bean wilt virus (CDFA, undated).
