Description
There are some very tough weeds on the prairies. They compete with valuable crop and forage plants and threaten many native plant species. Many of these weeds have been very expensive and difficult, if not impossible, to control with more traditional methods. In some instances, the chemicals used for control are non-selective compounds, which will also damage non-target plants and may leach out of sandy or gravelly soils, or compounds that give top growth control only. In addition, because of leaching, chemicals cannot be used on weeds that grow close to bodies of water. Many problem weeds are abundant in rangeland and along riverbanks and gullies, so the use of non-chemical control methods such as mowing or cultivation can be limited by the topography and size of these areas. These difficulties have prompted scientists to investigate a third alternative: the biological control of weeds.
