Indiana Pesticide Applicator Core Practice Exam

Which of the following formulations has no agitation requirements?

1. Dry flowables

2. Wettable powders

3. Granules

4. Soluble powders

The correct answer is: Dry flowables

The formulation that has no agitation requirements is granules. Granules are typically used for soil application and are designed to dissolve slowly, allowing for a steady release of the active ingredient without needing constant agitation. This slow-dissolving feature enables them to disperse evenly once applied, which is beneficial for efficacy in pest control applications. In contrast, dry flowables, wettable powders, and soluble powders generally require some level of agitation to maintain a uniform mixture in the spray solution. Without agitation, these formulations can settle or clump, leading to ineffective application and reduced pest control efficacy. Therefore, understanding the characteristics of granules in pesticide application helps ensure proper usage without the need for additional equipment or processes for agitation.
