Drift is the movement of a pesticide through air, during or after application, to a site other than the intended site of application. The affected area could be another crop, a garden or any other vegetation within range of the pesticide movement. In most cases, this movement is limited to the edges of the field or fence row. However, under certain conditions, off-target movement may affect areas at greater distances from the field. Problems occur when this movement affects a sensitive crop or another person's property.
