Aerial application, or what is informally referred to as crop dusting, [1] involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as aerial topdressing in some countries.
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".
Currently, all states have enforcement responsibility and most have certification authority. [22] The lead agency for pesticide regulation varies from state to state but it is typically the state department of agriculture. [23] FIFRA authorizes EPA to provide funding for state pesticide programs.
Ultra-low volume (ULV) application of pesticides has been defined as spraying at a Volume Application Rate (VAR) of less than 5 L/ha for field crops or less than 50 L/ha for tree/bush crops. VARs of 0.25 – 2 L/ha are typical for aerial ULV application to forest or migratory pests.
Pesticides are widely used by farmers to control plant pests and enhance production, but chemical pesticides can also cause water quality problems. Pesticides may appear in surface water due to: direct application (e.g. aerial spraying or broadcasting over water bodies) runoff during rain storms; aerial drift (from adjacent fields). [3]: p.2–22

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).
Herbicides, insecticides and pesticides are spray applied to soil or plant foliage to distribute and disperse these materials. See aerial application, pesticide application, sprayer. The control of spray characteristics is critical to provide the coverage of foliage and to minimize off target drifting of the spray to adjacent areas. (pesticide ...
