Wyoming Pesticide Applicator Certification Practice Test

How is Soil Injection commonly used in pesticide application?

1. The movement of a pesticide into soil by either mechanical means or irrigation.

2. To soak or wet the ground surface with a pesticide.

3. The placement of a pesticide below the surface of the soil.

4. The airborne movement of particles such as pesticide dusts and pesticide contaminated soil from the application site.

The correct answer is: The placement of a pesticide below the surface of the soil.

Soil injection is commonly used in pesticide application as a method of placing the pesticide below the surface of the soil. This technique helps target pests that are located in the soil itself or close to the root zone of plants. By injecting the pesticide below the soil surface, it can more effectively reach the target pests and provide long-lasting control. This method is particularly useful for controlling soil-dwelling insects or pests that may be difficult to reach with other application methods. To provide additional context: - Option A: The movement of a pesticide into soil by mechanical means or irrigation usually refers to soil incorporation, not soil injection. - Option B: Soaking or wetting the ground surface with a pesticide is more characteristic of surface application methods like spraying or watering. - Option D: The airborne movement of particles from the application site describes drift, which is a concern to be minimized in pesticide applications, but not specifically related to soil injection.
