Wyoming Pesticide Applicator Certification Practice Test

What is the function of Soil Application in pesticide use?

1. A particle of solid or liquid matter.

2. A suspension of fine matter.

3. To soak or wet the ground surface with a pesticide. Large volumes of the pesticide mixture are usually needed to saturate the soil to any depth.

4. A pesticide applied directly on or in the soil rather than on a growing plant.

The correct answer is: A pesticide applied directly on or in the soil rather than on a growing plant.

In soil application, the function is to apply the pesticide directly on or in the soil rather than on a growing plant. This method targets pests and insects that are in the soil or those that affect the plants by residing in the soil. By applying the pesticide directly to the soil, it can penetrate the ground and reach the target pests effectively. This method is particularly useful for controlling soil-dwelling insects, nematodes, and other pests that can cause damage to plants from below the ground surface. The other options are not correct because: A. This describes a particle of solid or liquid matter, which is not related to soil application in pesticide use. B. This describes a suspension of fine matter, which is not related to soil application in pesticide use. C. This describes the process of soaking or wetting the ground surface with a pesticide, which is more aligned with surface application rather than soil application. Large volumes of pesticide mixture are usually needed to saturate the soil to any depth, which is not the primary function of soil application.
