Georgia Pesticide Applicators Practice Exam

What type of application is commonly associated with granular pesticides?

1. Soil applied for pre-emergent weed control

2. Direct spray on foliage only

3. Fogging in enclosed spaces

4. Soil drenching for root uptake

The correct answer is: Soil applied for pre-emergent weed control

Granular pesticides are typically designed for soil applications, particularly for pre-emergent weed control. This method involves applying the granular formulation to the soil surface before weed seeds germinate, creating a barrier that prevents growth. The granules can effectively target soil-dwelling pests and diseases as they dissolve and disperse in moisture, delivering the active ingredients directly to the root zone of plants while minimizing movement into the atmosphere or onto non-target surfaces. Other application methods, such as direct spraying on foliage or fogging in enclosed spaces, are not standard practices for granular pesticides. Instead, these methods are better suited for liquid formulations that need to make contact with pests or surfaces. Additionally, soil drenching often utilizes liquid formulations for better absorption by plant roots. Therefore, the primary application method that aligns with the characteristics and intended use of granular pesticides is their application for pre-emergent weed control in the soil.
