Which application method typically involves applying pesticide to small, distinct areas?

Spot treatment is the correct choice because it specifically refers to applying a pesticide to small, targeted areas where pests or unwanted vegetation are present. This method allows for precise control and minimizes the exposure of the pesticide to non-target areas, making it especially effective for managing localized infestations without affecting the surrounding environment.

Other application methods function differently: rope-wick or wiper treatments involve using a tool that applies pesticide onto tall or dense vegetation but can cover larger areas. Crack-and-crevice applications focus on applying pesticides in narrow spaces or hidden areas where pests may reside, such as in the joints of floors or walls, but typically cover more surface area than just small spots. Soil incorporation involves mixing pesticides thoroughly into the soil before planting, which is more about overall soil treatment than targeted application.
