Which application method involves distributing pesticides from an aerial vehicle?

The method that involves distributing pesticides from an aerial vehicle is aerial application. This technique is primarily used for large areas where ground access may be difficult or inefficient. Aerial application allows for the quick and efficient treatment of vast landscapes, such as agricultural fields, forests, or golf courses.

Using aircraft to apply pesticides ensures even coverage and can reach areas that ground equipment might not easily access, such as steep terrains or remote locations. This method can also reduce the labor costs associated with ground application.

While granular application involves the use of solid pesticides in granule form spread over the land, injection refers to delivering pesticides directly into plant tissues or soil—neither of which typically involves aerial vehicles. Spraying also refers to the application of liquids, but it can occur with both ground-based and aerial methods; hence, it is not specific to aerial distribution. Aerial application, however, distinctly indicates the use of airborne equipment, making it the correct answer.
