What is the role of tarps in non-soil fumigation?

Tarps play a crucial role in non-soil fumigation by serving to contain the fumigant within the treatment area. This containment is vital for ensuring that the fumigation process is effective, as it prevents the escape of gas into the atmosphere, allowing the fumigant to remain concentrated in the designated area for an adequate duration. This concentration is essential for achieving the desired level of efficacy against pests and pathogens.

By effectively sealing the area, tarps help to maintain the necessary conditions for penetration and absorption of the fumigant, ultimately leading to better pest control outcomes. The use of tarps also protects the environment and reduces potential hazards for humans and non-target organisms by minimizing fumigant exposure.
