Risk Area: Ensure the risk area and surroundings are free of unprotected personnel (up to 3m).
During fumigation, the risk area must be marked with a physical barrier. The size of the risk area depends on the risk, but it must be at least: 3 meters from the enclosure outside
Methyl Bromide: This is one of the fastest-acting chemicals available and is used as a quarantine chemical for outbreaks. It is applied to the soil by injection, and a waiting period is required before planting to allow the chemical to dissipate.
Chloropicrin: This is a broad-spectrum fumigant with fungicidal, herbicidal, insecticidal, and nematicidal properties. It is better at controlling fungi and bacteria than methyl bromide, but methyl bromide is better against weed seeds and nematodes.
