Which application method is commonly used in aerial spraying?

The swath application method is commonly used in aerial spraying because it allows for efficient coverage of large areas. This technique involves applying pesticides or fertilizers in a strip or "swath" across the field, ensuring that the chemicals are evenly distributed over the targeted crop areas. Aerial application is particularly suited for swath application due to the capability of aircraft to cover extensive areas quickly and reach locations that may be difficult for ground equipment to access, such as wet or muddy fields.

Using swath application enables precise targeting and minimizes the risk of missing areas, which can occur with other methods. This method also helps in reducing the amount of pesticide used, resulting in economic benefits and minimizing environmental impact. Therefore, when considering the most effective and commonly employed method in aerial spraying, swath application stands out as the optimal choice.
