Rasmussen, I. and Askegaard, M. (2004) Crop rotation limits Canada thistle, but not Couch grass or annual weeds. DARCOFenews (4).
Direct weed control of annual as well as perennial weeds was necessary to reduce the amount of weeds in organic crop rotation experiments at three locations in Denmark. For Canada thistle, however, the rotation was the most important controlling factor: the rotation with grass-clover had less thistle biomass than the one without.
