What is the minimum thickness of polyethylene traps that can be used for tarp fumigation?

The minimum thickness for polyethylene traps used in tarp fumigation is established to ensure that the traps can effectively contain the fumigant. A thickness of 1 1/2 mil provides an adequate barrier that balances durability and flexibility, preventing leaks that could compromise the fumigation process. This thickness is sufficient to withstand environmental conditions while maintaining the integrity necessary to keep the fumigant contained during the treatment period. Choosing a thickness lower than this could lead to potential failures in the fumigation process, allowing the gas to escape and diminish the efficacy of pest control efforts. Therefore, 1 1/2 mil is recommended as the minimum thickness for effective tarp fumigation.
