Commodity Fumigation License Practice Exam

What could be a consequence of not ensuring all areas reach toxic levels when fumigating?

1. Increased pest resistance

2. Partial pest kills

3. Complete pest elimination

4. No consequences

The correct answer is: Partial pest kills

When fumigating, ensuring that all areas reach toxic levels is crucial for effective pest control. If certain areas do not achieve these levels, it can result in partial pest kills. This outcome occurs because the pests that are not exposed to sufficient concentrations of the fumigant may survive and potentially continue to reproduce. Partial pest kills undermine the effectiveness of the fumigation process, as any surviving pests can lead to the establishment of a new population, which may be more challenging to control in the future. Additionally, these surviving pests might develop resistance to the fumigant, further complicating management efforts. In contrast, achieving thorough penetration and ensuring that all areas are adequately treated is essential for maximizing pest mortality and minimizing the risk of re-infestation. Complete pest elimination is the desired result of effective fumigation, but it can only be achieved if every area is properly treated. Without ensuring adequate levels, the result will not be complete elimination but rather a scenario where some pests survive and may pose ongoing issues. Therefore, the consequence of inadequate toxic exposure during fumigation is indeed partial pest kills.
