Which spray type is specifically designed to minimize chemical contact with non-target vegetation?

The spray type that is specifically designed to minimize chemical contact with non-target vegetation is directed sprays. This method involves aiming the pesticide application directly at the target area or plant while avoiding surrounding vegetation. Directed sprays are beneficial in maintaining the health of non-target plants and minimizing unintended exposure to nearby flora.

In contrast, uniform treatment applies the pesticide evenly across a broad area, which increases the likelihood of affecting non-target plants. Band treatment, while it reduces the area where pesticides are applied, might still impact some non-target vegetation close to the treated band. Chemigation involves applying pesticides through irrigation systems, which can broadly distribute chemicals to areas that may include non-target vegetation. Thus, directed sprays are the preferred method for protecting non-target plants while effectively treating the desired target.
