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.
water or other liquid broken up into minute droplets and blown,
