Drift refers to the airborne movement of a pesticide spray, dust, particle, or vapor beyond the target area. Common pesticides known to drift include 2,4-D dicamba, a broadleaf herbicide. Temperature can play an important role in helping reduce pesticide drift. High temperatures may cause chemicals to volatilize and cause vapor drift, even on days with appropriate wind conditions. You can help prevent drift damage by applying pesticides when winds are within 3-10 mph and in temperatures of 80-90F.
