An agricultural aircraft is an aircraft that has been built or converted for agricultural use – usually aerial application of pesticides (crop dusting) or fertilizer (aerial topdressing); in these roles, they are referred to as "crop dusters" or "top dressers".
Pesticide application can artificially select for resistant pests.
