Description

The spread and persistence of common toadflax (Linaria vulgaris) when growing alone and in competition with alfalfa (Medicargo sativa) maintained as a hay crop in central Alberta Canada was monitored over a four year period. Competition from alfalfa reduced the rate of spread of the weed, and multiple harvests of the crop prevented toadflax seed set. The presence of the weed did not significantly affect the yield of alfalfa.
