The boom is mounted on the rear of the trailer frame. A sprayer mounted on a skid frame can be carried in a pickup truck or placed on a trailer. This type of sprayer usually has a tank, engine, and boom. The boom can be mounted on the skid or on the rear of the pickup or trailer. This type of sprayer probably would not be a first choice for small orchard crops.
Water is used as both the diluent and the carrier.
The sprayer must provide and maintain high pressure and sufficient flow of liquid so that the large droplets of the stream can reach the tops of the trees. Although handgun sprayers are primarily used for spraying trees, they can be used on small fruit on a limited basis and may be used in combination with a boom sprayer. A multiple-outlet gun creates a small boom for small fruit. The handle of the gun can be twisted to control the spray angle. Hydraulic handgun sprayers differ in construction to satisfy the different kinds of tasks for which they are used.
