Users should be aware that weed seeds discussed in the bulletin represent a very small number of species of weed seeds that could potentially occur in oilseeds crops. The weed seeds discussed in this bulletin were selected based on being problematic in grain cleaning, end product quality or similarities in visual seed identification to oilseeds crops or other weed seeds of concern.
