How are granular pesticides typically used?

Granular pesticides are specifically formulated for application onto soil surfaces, which is why this choice is the correct one. The granular form allows for slow and controlled release of the active ingredients, making these pesticides particularly effective for targeting soil-dwelling pests or delivering pest control to areas where insects may reside or feed.

When applied to the soil, granular pesticides can penetrate the soil profile, allowing them to reach pests that live beneath the surface or in that top layer of soil. This method of application is advantageous because it minimizes drift and exposure to non-target organisms compared to other application methods.

While granular pesticides can affect pests above ground indirectly, their primary benefit is derived from their application to soil, enabling them to act on pests that interact with the soil. This differentiates them from liquid formulations that are more often used in broadcast applications or for creating aerosols.
