Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
non-target-micro-organisms
According to Commission Directive 96/12/EC the effects on non-target micro-organisms of the active substance must be investigated. No studies are supplied for this point. Methyl bromide is intended for use as a space and pre-planting soil fumigant. It is proposed that the potential impact on soil microbial activity need not be investigated for space fumigation, as preparations containing methyl bromide are proposed for application to stored products and not proposed for application in the environment. When soil incorporated, it will be expected that it will have a negative effect on the populations of non-target micro-organisms in the soil. The use of methyl bromide in some situations must be balanced against the negative aspects of its use. Although methyl bromide is expected to cause a negative effect on the populations of soil non-target micro-organisms this is balanced against the improvement in crop quality. Repeated exposure is also not expected, as methyl bromide will only be applied once per year. This should enable the populations of soil non-target micro-organisms to sufficiently recover.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
