Cropduster
Aerial application, or crop dusting, 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. In the USA in 2018 about 25% of pesticides used on commercial farms, and about 100% of forestry products are applied aerially. The European Union severely limited aerial application of pesticides in 2009 and other products because of environmental and public health hazards like spray drift.
