What are the limitations of using herbicides?
In addition to the limitations caused by herbicide spectrum and carry over discussed above, if applied inappropriately, herbicides can damage crops. In addition, herbicide drift can harm neighboring crops. As is true of all agricultural pest control strategies, weeds can evolve to develop resistance to herbicides. In addition, the continued use of herbicides will cause the spectrum of weeds in a field to shift to those that are more difficult to control with herbicides.
