Crop spraying is the process of spraying insecticides, pesticides, fungicides and other preventative treatments onto crops. Previously known in agricultural services as 'crop dusting,' the process is used to cover large areas of crops and protect them from local bugs and pests. When you press down on the sprayer or pump head, the piston presses down into the chamber. Whatever is in the chamber needs to escape, and the easiest path is up through the stem and out the nozzle. As soon as you release the sprayer head, the chamber fills up with liquid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle. Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray.

In a low-volume (LV) sprayer, spray material in a water or oil carrier is injected into a high-speed air stream developed by a fan, blower or compressor. In most LV sprayers, a small pump is used to inject a concentrate pesticide solution into the air stream. The speed of the air stream may be as high as 200 mph. Advantages include delivering spray to hard-to-reach places, such as trees, as well as application at high pressure and high capacity or low pressure and low volume. A disadvantage is that spray guns are not suited for treating large areas. The major components of a sprayer are tank, pump, agitator, flow control, and nozzles. Sprayer tank, wand, pump and gauge. Use synthetic rubber or plastic hoses that have a burst strength greater than peak operating pressures, resist oil and solvents present in pesticides, and are weather resistant.

The main function of a sprayer is to break the liquid into droplets of effective size and distribute them uniformly over the surface or space to be protected. Another function is to regulate the amount of insecticide to avoid excessive application that might prove harmful or wasteful.Conversion of spray liquid into droplets is achieved using some form of energies. Various forms of kinetic energies such as hydraulic, gaseous and centrifugal are utilized in this process. The type of sprayer and nozzles or atomizers can be classified according to the energy used.

It consists of a piston type pump, a platform with fork, a lever to operate the pump, pressure chamber, suction hose with strainer, delivery hose, and a spray gun with flow control knob and nozzle.
