ABSTRACT
Pesticides are usually applied as liquid sprays or solids
(e.g., dusts and granules). Vehicle-mounted application
platforms usually involve spraying using aircraft (aerial
application), ground rigs, orchard airblast, or chemigation.
Hand-held equipment includes lever-or engine-operated
knapsack sprayers, and a variety of other sprayers such as
spinning disc and electrostatic sprayers. These tend to be
more common in developing countries where labor is often
cheaper than aircraft or ground equipment. Information on
hand-held applications can be found elsewhere.[1]
