What are flexible tubes filled with water or sand used for in fumigation?

Flexible tubes filled with water or sand are primarily used to seal tarpaulins to the ground in fumigation processes. This sealing is crucial as it prevents gas from escaping, ensuring that the fumigant remains contained within the target area for the duration of the fumigation treatment. Proper sealing is essential for the effectiveness of fumigation, as it maximizes exposure to the pest problem while also aiding in regulatory compliance regarding air safety and environmental protection.

While these tubes can be linked to other aspects within the context of fumigation—such as helping in the application process or indirectly influencing air quality through better containment—their main function is specifically related to sealing the tarpaulin to ensure that the environment remains: secure. This containment is vital to achieve the desired concentration of the fumigant for effective pest control.
