Avoiding excessive spray drift is a key objective for applicators. With increasing acreage planted to herbicide-resistant crops and a shift to more postemergence spraying, the potential for off-target plant damage has increased in recent years. Off-site damage is often readily apparent in adjacent farmland and rural acreages. As increased emphasis is placed on drift-reduction, nozzle manufacturers have responded with new nozzle types designed to lower drift potential and accommodate new application technologies. Precision agriculture and site-specific farming have added additional demands for nozzles than can accommodate a wider pressure operating range.
