Velocity is important for getting the spray to the top of the trees or across a field. Most airstreams lose 75 percent of their velocity in the first 25 feet from the sprayer. Airblast sprayers can spray an area in less time than either handgun or boom sprayers can. However, airblast sprayers require more power than boom or handgun sprayers do. Because airblast sprayers apply a concentrated pesticide mixture, a much smaller amount of water is used in comparison to the amount used in hydraulic or boom sprayers.
Pesticide drift can be a serious problem since airblast sprayers are broadcast sprayers.
Sprayer Selection Selecting which sprayer to use is not always easy. Powered and manual sprayers are available in sizes appropriate for small orchards and farms. When considering the type of sprayer for your operation, keep in mind the various uses you may have for the sprayer. You should also consider how you will move and power your sprayer. If not, you may need to purchase a separate engine to operate the sprayer.
