Aerial application, commonly called crop dusting, involves spraying crops with fertilizers, pesticides, and fungicides from an agricultural aircraft. The specific spreading of fertilizer is also known as aerial topdressing.
Agricultural aircraft are often purpose-built, though many have been converted from existing airframes. Helicopters are sometimes used, and some aircraft serve double duty as water bombers in areas prone to wildfires.

Famous quotes containing the words aerial and/or application:
“But with some small portion of real genius and a warm imagination, an author surely may be permitted a little to expand his wings and to wander in the aerial fields of fancy, provided ... that he soar not to such dangerous heights, from whence unplumed he may fall to the ground disgraced, if not disabled from ever rising anymore.”
—Sarah Fielding (1710–1768)
“Great abilites are not requisite for an Historian; for in historical composition, all the greatest powers of the human mind are quiescent. He has facts ready to his hand; so there is no exercise of invention. Imagination is not required in any degree; only about as much as is used in the lowest kinds of poetry. Some penetration, accuracy, and colouring, will fit a man for the task, if he can give the application which is necessary.”
—Samuel Johnson (1709–1784)
