What are Agricultural sprayers?

A sprayer is a device used to spray a liquid, where sprayers are commonly used for projection of water, weed killers, crop performance materials, pest maintenance chemicals, as well as manufacturing and production line ingredients. In agriculture, a sprayer is a piece of equipment that is used to apply herbicides, pesticides, and fertilizers on agricultural crops. Sprayers range in size from man-portable units (typically backpacks with spray guns) to trailed sprayers that are connected to a tractor, to self-propelled units similar to tractors with boom mounts of 4–30 feet (1.2–9.1 m) up to 60–151 feet (18–46 m) in length depending on engineering design for tractor and land size.

Agricultural sprayers have been engineered to optimize their applicability and performance for the many purposes that the machines are put to, whether being used on crops, vegetation, or soil. Agriculture sprayers are often used for applying water and water/chemical solutions containing acids or caustic materials for crop-performance or pest-control; i.e. fertilizers and pesticides.

Types of Agricultural Sprayer

There are many types of sprayers that are used in the farming or agricultural industry.

Low-Pressure Agricultural Sprayers

A low-pressure sprayer is used to provide constant nozzle pressure. These sprayers come in different types, namely, tractor-mounted, trailer-mounted, and truck-mounted. Depending on the vehicle you have and the size of the area you need to spray, you need to select a low-pressure sprayer that can fit enough gallons to finish the job.

The Truck-mounted sprayer can fit up to 2,500 gallons in its tank and can boom up to 60 feet, making it the best option for vast applications. While the Trailer-mounted sprayer. for medium applications, a trailer-mounted sprayer should do the job. The tank of a trailer-mounted sprayer can have a capacity of 1000 gallons, with a boom reaching 12 to 50 feet. Tractor-mounted sprayer, and the tractor-mounted sprayer is the smallest type of low-pressure sprayer, with a capacity of 150 to 500 gallons only.

High-Pressure Agricultural Sprayers

High-pressure sprayers are designed to reach tall trees and thick brush. Compared to low-pressure sprayers, this type of sprayer is heavier and more expensive. However, it can emit pressures of up to 1,000 psi.

Air-Carrier Sprayers

Also known as air-blast sprayers or mist blowers, air-carrier sprayers use high-speed air to deliver pesticides at speeds of 80 to 150 miles. Because the air disperses the pesticide while spraying, the pesticide used in air-carrier sprayers is concentrated. Hence, there is less time needed for diluting and re-filling the tank.

 Airless sprayer

Hand-Operated Agricultural Sprayers

This is a simple machine with an air pump inside to release pressurized air from the nozzle. A hand-operated agricultural sprayer is a manual hand-compression sprayer that consists of a tank for holding a liquid insecticide formulation, which can be pressurized by means of a hand pump attached. The compressed air forces the liquid from the tank via a hose with a cut-off valve, a lance and a nozzle.

A hand-operated sprayer is not meant for wide distribution because when the pressure drops too low, you must wait for it to go back up until you can spray again. Nevertheless, it is the cheapest type of sprayer for agricultural purposes.


Common Uses Agricultural Sprayer


The new drone sprayers are equipped with software that follows a specific path for mapping. They are equipped with cameras and sensors onboard that take pictures automatically. Other drones are equipped with GPS to measure farm sizes and to monitor areas that need spraying attention. In addition, they are capable of carrying more pesticides and fertilizers without tampering with crops as compared to tractors. It also helps in reducing pesticide exposure to humans that would have sprayed manually.

Liquid fertilizer application

Liquid fertilizer application is the appropriate use in dryland. This sprayer is parked with liquid fertilizer to make this method efficient. It is the perfect choice because of its ability to target a specific crop without losing a lot of liquid to the winds or evaporation. Furthermore, this type of spraying is very beneficial for crop growth and early rooting. Although the main purpose is to supply crops with nutrients.

Spraying water

A water sprayer is a device used to spray water on plants and animals. Apart from spraying pesticides and fungicides, sprayers can be used to hydrate plants and animals. There are high-pressure sprayers that are used over small areas for irrigation. Additionally, before crops are harvested they are sprayed with fresh water to clean any chemical deposits that could have been left behind. During hot weather, sprayers are used to cool livestock and insects that are kept for agricultural purposes.

Spraying fungicides

Fungi, blight, and rusts are controlled by the use of a hand sprayer. They are the plant’s worst enemy because they lower crop production. Parasitic fungi affect the animals as well. But with the help of a hand sprayer, a farmer is able to control them. Most fungicides are sold in liquid form and contain 90% Sulphur. Sprayers are very effective when it comes to controlling the fungi since most of them affect the leaves.

Pest control

Agricultural pest sprayer is one of the most efficient gadgets that is used for controlling pests. Pesticides are mixed with water and then sprayed to areas infested. In areas that are highly infested, spraying is done every two weeks. It is also sprayed on the livestock to kill ticks and other dangerous pests that lower production. Houses are also sprayed to get rid of mosquitoes, cockroaches, ants, bed bugs, reptiles and so on.

Spraying herbicides

Unwanted vegetation is controlled by the help of sprayers. To achieve this, the herbicide is mixed with water inside a sprayer. The farmer then sprays over the unwanted vegetation which dries up after a few days. In the past farmers were able to spray in a piece of land with unwanted vegetation only. However, scientists introduced new chemicals that can select and eliminate unwanted crops in the same land. The selective herbicides are administered using a sprayer too.

Frequently Asked Questions about Agriculture Sprayer

Q1- How do manual agricultural sprayer work?

 You pump the trigger up and down, forcing air (initially) from the nozzle. The air inside the top of the bottle is at higher pressure than the air in the tube, so it pushes down on the liquid. The liquid is forced up the tube toward the pump mechanism. The liquid leaves as a fine mist of aerosol spray.

Q2- What is a crop sprayer used for?

 In agriculture, a crop sprayer is a piece of equipment that uses spray nozzles to apply controlled doses of herbicides, pesticides, and fertilizers to agricultural crops.

Q3- Why do farmers use sprayers?

While sprayers were once a niche product, today sprayers have become an essential piece of farm equipment for effective crop production. By properly applying chemicals to control weeds, insects, and diseases, you give your crop the best chance for high yields.

Q4- What kinds of chemicals are used in agriculture?

The different types of chemicals used in agriculture are:

  • Herbicides (To kill weeds)
  • Insecticides: (To kill bugs)
  • Fungicides: (To get rid of disease)
  • Soil fumigants, desiccants, harvest aids, and plant growth regulators.
