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.
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. water or other liquid broken up into minute droplets and blown ejected into, or falling through the air. a jet of fine particles of liquid, as medicine, insecticide, paint, perfume, etc., discharged from an atomizer or other device for direct application to a surface.
a mass of small drops of liquid spread onto plants and crops, etc. from a special piece of equipment, or the piece of equipment itself Farmers use a lot of chemical sprays on crops. Fewer examples. She could feel the spray from the water on her skin. 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.
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.

Lower Cost – Electric sprayers are generally simpler, have fewer parts, and are much cheaper than gas-powered sprayers. Typically, the pump and motor are one unit, which is cheaper (compared to gas power) and requires no extra assembly, saving labor and assembly costs.
