Minnesota Pesticide Applicator Practice Test

Should you choose a pesticide formulated as a high-volatility product to avoid vapor drift?

1. Yes

2. No

3. Only in windy conditions

4. Only when necessary

The correct answer is: No

Choosing a pesticide formulated as a high-volatility product is not advisable if the goal is to avoid vapor drift. High-volatility formulations have a tendency to evaporate into the air more readily, which increases the risk of vapors drifting away from the application site. This can lead to unintended exposure of non-target areas and organisms, potentially causing environmental harm and regulatory issues. In contrast, selecting a pesticide with lower volatility helps mitigate the risk of drift. Low-volatility products are less likely to volatilize and enter the air as vapors, thus reducing the chances of drifting during or after application, especially under varying weather conditions such as wind or temperature changes. To ensure safety and effectiveness, it is crucial to select pesticide formulations that align with best management practices for drift reduction, such as using low-volatility products and adhering to application guidelines.
