Indiana Pesticide Applicator Core Practice Exam

In comparison to other forms, how do granules reduce inhalation risks?

1. They have a less volatile composition

2. They are less likely to drift

3. They dissolve quickly in water

4. They are easy to apply even in windy conditions

The correct answer is: They are less likely to drift

Granules are designed with a combination of physical properties that make them less likely to drift compared to other pesticide formulations, such as powders or aerosols. Unlike these other forms, which can release fine particles into the air, granules are heavier and tend to settle quickly to the ground upon application. This reduced potential for aerial dispersal means that there is a significantly lower chance of inhalation by applicators or bystanders, promoting a safer application process. The other options do have relevance in specific contexts; for example, while granules may have a less volatile composition and can dissolve in water, these aspects do not directly address the inhalation risks. Being easy to apply in windy conditions does not adequately mitigate the risks associated with inhalation either, since windy conditions themselves raise concerns about drift regardless of the application method. Thus, the key advantage of granules lies in their tendency to remain in the application zone, reducing the likelihood of inhalation exposure.
