In simple terms, a boom sprayer is used to spray a chemical over a large area. … They can also be used to spray water on dirt tracks or horse ménages, to keep dust at bay. Booms come in many different sizes, with large agricultral booms exceeding 100ft, and smaller towed booms being used for smallholdings and estates.
Sprayers are fully integrated, mechanical systems, meaning they are composed of various parts and components that work together to achieve the desired effect, in this case: the projection of the spray fluid. This can be as simple as a hand sprayer attached to a bottle that is pumped and primed by a spring-lever, tube, and vacuum-pressure; or as complex as a 150 foot reach boom sprayer with a list of system components that work together to deliver the spray fluid.
