What type of application method produces an extremely fine mist and can be portable or aircraft mounted?

The application method that produces an extremely fine mist and can be portable or aircraft mounted is the fogger. Foggers work by generating very small droplets of a liquid pesticide, creating a mist that can effectively disperse the pesticide over a large area. This technique is particularly useful in controlling pests in large aquatic environments, as the fine mist allows for better coverage and penetration into areas where pests may be hiding.

Additionally, fogging is a versatile method, as it can be applied using portable devices for localized applications or mounted on aircraft for broad-area treatments. This adaptability makes foggers a popular choice in aquatic pest control, especially when dealing with insect populations or invasive aquatic species in lakes, ponds, or rivers.

Granular applications are typically used when targeting pests in soil or sediment, and are not designed to produce a fine mist. Diaphragm and piston pumps are equipment types that may be used in various application techniques but do not directly refer to the method that creates a fine mist.
