Agriculture sprayers are complete spray systems engineered for generating pressure to drive spray fluid from a tank out to the sprayer’s nozzle(s) to crop or soil. Sprayers feature a range of specifications that influence their performance abilities and suitability for specific work cases. Understanding the different sprayer models and their characteristics can help you select the best sprayer for the job.  Ten common sprayer solutions are available in today’s industry: backpack, spot, ATV, UTV, tow behind, truck bed, 3 point hitch, boom, boomless, and mist. Sprayers can vary in their nozzle quantities, maximum PSI pressure and GPM flow rates, the sprayer pump type, tank gallon volume range, potential max spray coverage, system overall maneuverability, and total hose and nozzle reach. Sprayers are most often used for the administration of water, insecticides, pesticides, herbicides, and fertilizer. The cost of a sprayer ranges from $50 to $10,000, depending on the sprayer’s specifications.

Sprayer Selection Considerations

  1. Know your job and what the sprayer will be used for; e.g. Perimeter treatments; spot applications; row crops; grow operations

  2. Understand modern sprayer types, the model differences, and their optimum work use scenarios; e.g. Boomless sprayers for wide-swath coverage of hard-to-reach areas; mist sprayers for full-depth spray coverage; truckbed sprayers for high capacity, high pressure mobility

  3. Determine the right sprayer’s performance specifications and equipment components

  4. Determine any specific chemical compatibility considerations with the sprayer pump, hose, and gasket compatibility

Example Sprayer Selection: Vineyard pesticide use sprayer, 400 gallon truck-bed sprayer for increased hill mobility, featuring dual 300ft. hoses, dual high pressure nozzles, and 18 GPM max centrifugal sprayer pump.

Agriculture Sprayer Specifications
When you choose a job-specific sprayer to maximum spraying performance, it is important to know the requirements. There are nine variables in spraying applications that you should consider:

  • Spray Area Size

  • Spray Target and Spray Fluid

  • Spray Location and Terrain

  • Sprayer Fluid GPM Rate

  • Sprayer Fluid PSI Pressure

  • Total Spray Project Fluid Volume

  • Sprayer Tank Gallon Capacity

  • Spray Application Frequency

  • Spray Application Duration

Engineering
Sprayers are designed as full spraying systems with a pump and plumbing components to pressurize and drive the spray fluid from a tank and deliver to the spray nozzle(s) a consistent pressure stream optimized for the target application. To achieve this, these sprayer components are often used: pressure regulators, valves, in-line strainers, handguns, hoses and reels, and folding boom arms.

Engineers design sprayers with specific materials that must be compatible with the chemicals that are commonly used in agriculture spraying operations. Gasket materials and compatibility can vary within sprayer systems. Common sprayer materials include: high-density polyethylene (HDPE; fluid tank); steel (boom arms; pumps); stainless steel (fittings; handgun parts; pumps); PVC (polyvinyl chloride; plumbing); XLPE (cross-linked polyethylene, also PEX; plumbing).

Sprayer Performance and Operation Ranges
Each sprayer has different performance characteristics in terms of volume capacity, pressure and GPM flow rates, spray coverage, boom compatibility, and hose lengths. These characteristics dictate which sprayer is ideal for your application. Review the tables below to compare available sprayer specifications and associated costs:

Boom Sprayers

Modern inventive advancement of the single spray nozzle to a system with up to 18 nozzles, covering up to 30 feet of spray area with the largest of boom attachment arms. Boom sprayers are extendable, folding arms with equally spaced nozzles designed for the bulk administration of a spray fluid. They are engineered to install on various vehicles as well as sprayer tanks, pumps, and nozzle heads, system components many boom models need fitted with prior to use, especially if seeking specific flow rates or nozzle output.

Boom sprayers are often fitted with diaphragm or roller sprayer pumps, but other sprayer pump models can be used. Booms feature from 2 to 18 nozzles, range from 4 to 30 feet, and have flow rate and pressure maximums dependent on pump type. Commonly used boom lengths are 12ft, 20ft, and 30ft.

Boomless Sprayers
Also known as “No Booms,” boomless spray nozzles are engineered for increased distance and wide swath spray projection. No boom nozzles feature versatile vehicle mounting for mobile spray delivery up to 30ft, often in fan-type coverage patterns. Common vehicle installation is on small tractors, utility vehicles, farm tractors, ATVs and UTVs. Well-operated boomless sprayers potentially provide significant spray coverage and can be very useful and cost-effective in applications. They are commonly used for spray access to areas that are hard-to-reach by vehicle or other sprayer types, especially booms, with examples being dense vegetation, tree lines, tall grass and crops, ditches, levees, roadway right-of-ways, and perimeters.

Boomless sprayers require a self-provided sprayer pump and are commonly used with diaphragm or roller pumps. Tank capacities, flow rates, and max pressure varies with the system installation and the boomless nozzle capabilities. No boom nozzles are available in 1 to 5 nozzle tip quantities, for multi-directional spray coverage, and capabilities of 1.0 - 36 GPM flow rates and max pressures up to 60 psi.

Mist Sprayers
The greatest spray coverage among the sprayer models, the engineering of mist sprayers further distributes spray fluid molecules into smaller-sized droplets to produce a fine spray mist that increases the fluid’s coverage abilities across its spray targets. Designed for versatility and uniformity in work scenarios, mist sprayers are well-suited for trees, crops, shrubs, and general vegetation as in fruit and nut trees, groves and orchards, berry bushes, row crops, tall crops, and thick tree lines.

Mist sprayers are full sprayer systems powered by PTO mount roller pump or a gas powered centrifugal pump. They are often mounted to utility tractors as well as ATVs/UTVs, and have 25 to 100 gallon tank capacities, 1.0 – 22 GPM nozzle flow rate, a vertical distance reach up to 95 feet, and a horizontal distance reach up to 180 feet. Mist sprayers feature cannon volute nozzles for dispersed, targeted spraying that is capable of 210°degree rotation for full left and right alternation.
