A sprayer is a device used to spray a liquid.

In agriculture, a sprayer is a piece of equipment that uses spray nozzles to apply controled doses of herbicides, pesticides, and fertilizers to agricultural crops. Sprayers range in size from man-portable units (typically backpacks with spray guns) to self-propelled units similar to tractors, with boom mounts of 60–151 feet in length.


The machines all incorporate a tank to contain the water and chemical mix with a high pressure pump to distribute it through small bore pipes along a boom to nozzles at intervals along the boom. Modern machines has also a system to mark the end of the booms spray width to follow for the next row to avoid misses or double dosing. But the latest high tech systems use GPS & computerised controls to control the machine


They come in 4 main types for agricultural use;

  • Self propelled - Used by contractors and estates. purpose built often fitted with complex telemtry systems and damped booms to reduce bounce.
  • Trailed - towed by a tractor
  • Mounted - fits on tractors 3-point linkage (limited capacity & boom size)
  • De-mountable - Fittes on a too carrier or forward control tractor but is lifted off when not required and replaced by other equipment, such as a fertiliser or lime spreader body. Makers like Multidrive provide dedicated power units for this type of application

There are also a number of other types of sprayer used for applications other than agricultural use in large fields.

  • Backpack/knapsack - used round small trees and for weed killer around building and paths. Also used to spray individual weeds in meadows & paddocks.
  • Stirrup pump sparayer (Foot operated) - older tool genarally used in greenhouses and orchards
  • Garden & Horticultural sprayer
  • Hand sprayer (compression) - bicycle pump type originally used by the Victorians in greenhouses and small orchids for insecticide
