Fumigation works by converting a solid into a lethal gas which is dispersed within an enclosed area and maintained at a prescribed concentration for a specified period to eliminate target pests. In Minnesota, fumigation is commonly used to treat grain infested with pests and to treat soil in potato production.
How does fumigation work?
Fumigation works by converting a solid into a lethal gas which is dispersed within an enclosed area and maintained at a prescribed concentration for a specified period to eliminate target pests. In Minnesota, fumigation is commonly used to treat grain infested with pests and to treat soil in potato production.
Fumigation requires several steps:
- Prepare site and determine dose;
- Complete a Fumigation Management Plan (FMP) if required by product label;
- Application;
- Lockout site;
- Monitor and reapply to maintain lethal concentration if necessary;
- Monitor air temperature which may affect fumigation rate;
- Complete fumigation period;
- Aerate fumigated space;
- Collect and deactivate any unused fumigant;
- Dispose of any non hazardous wastes; and
- Clear area for reentry.
The time recommended on the label is the minimum time necessary to complete the fumigation process. The end time cannot be pre-determined because the process could slow down with conditions. End time can only be determined by monitoring fumigant levels in the container over a period of time.
