Commodity Fumigation License Practice Exam

What is the ideal temperature range for effective fumigation?

1. 40-60°F

2. 65-95°F

3. 50-70°F

4. 70-100°F

The correct answer is: 65-95°F

The ideal temperature range for effective fumigation is typically between 65°F and 95°F. This range is crucial because higher temperatures generally enhance the efficacy of fumigation agents, allowing them to penetrate materials better and reach the pests more effectively. At temperatures below this range, particularly at lower temperatures like 40°F to 60°F, the chemical reactions involved in the fumigation process can slow down significantly, reducing the effectiveness of the fumigant. Similarly, while temperatures between 50°F and 70°F may seem conductive to fumigation, they still do not maximize the effectiveness compared to the higher range. On the upper end, temperatures exceeding 95°F may create a risk of increased volatility of fumigants, which can lead to loss of efficacy and potentially hazardous exposure to workers if proper safety measures are not followed. Therefore, the range of 65°F to 95°F strikes a balance that ensures optimal performance of the fumigants and safety during the operation.
