Sprayer speed affects drift potential

Accelerated, early planting in some parts of the state increases pressure on applicators of preemergence herbicide to speed up sprayers to cover a larger numbers of acres. Increased speeds increase boom pressure for existing nozzles, and can tempt applicators to increase boom height. Both increase drift potential. 

If travel speed increases, consider using a slightly larger nozzle size to maintain desired droplet size and keep spray booms within 2 ft of the target.
