Bromofenoxim is an obsolete phenoxy selective herbicide. It has a low aqueous solubility and is not considered highly volatile. It is not expected to be persistent in soil or water systems. Nor is it expected to leach to groundwater. It has a low to moderate toxicity to most fauna and flora. Bromofenoxim is moderately toxic via the oral route to mammals but other health related information is scarce.
