Structural Pest Control Applicator Practice Exam

For what kind of job would you use a spreader-sticker?

1. For weed and brush control

2. For treatment of waxy leaf surfaces

3. For treatment of hard-to-reach tree tops

4. For surface pest control

The correct answer is: For treatment of waxy leaf surfaces

A spreader-sticker is specifically designed to enhance the adhesion of pesticides and other treatments to certain types of surfaces, particularly those that are waxy or have a smooth texture. When applied to plants with waxy leaves, spreader-stickers enable the active ingredients in pesticides to better penetrate and adhere to the surface of the leaves. This improves the efficacy of the treatment by ensuring that the product remains on the surface long enough to take effect, rather than being washed off by rain or dew or simply sliding off the slick surface. Other options, while relevant to pest control, do not specifically rely on the unique properties of spreader-stickers. For instance, weed and brush control would typically involve different application methods such as herbicides that do not require enhanced adhesion for effective treatment. Similarly, treating hard-to-reach tree tops and surface pests may engage different strategies or equipment that focus more on delivery methods than on enhancing surface adhesion.
