What is the primary advantage of recirculation fumigation compared to gravity fumigation?

• A. Gas remains in equal proportions
• B. Lower cost of operation
• C. Faster application process
• D. Less need for monitoring

Answer: (A)

The primary advantage of recirculation fumigation is that gas remains in equal proportions throughout the fumigation space. This method involves circulating the fumigant within the enclosed area, ensuring a more uniform distribution of the gas. As a result, all areas receive the same concentration of the fumigant, which enhances the effectiveness of pest control. This uniformity is crucial for achieving optimal results since different areas can have varying degrees of pest infestation and gas penetration. In contrast, gravity fumigation can lead to uneven gas distribution, with some areas potentially receiving higher concentrations of the fumigant while others might be underexposed. This can result in ineffective pest control, as certain pests may survive due to insufficient exposure to the fumigant. While lower cost of operation, faster application processes, and reduced needs for monitoring are beneficial aspects of fumigation practices, they do not significantly contribute to the uniformity and reliability of gas distribution, which is the standout advantage of recirculation fumigation.
