SUMMARY |
Chlordimeform in an insectiicde and acaricide that is not approved for use in the EU. It is moderately soluble in water and highly soluble in many organic solvents. It is volatile. Under normal conditions is would not be expected to leach to groundwater. It is moderately persistent in soil systems but would not be expected to persist in water systems. It is moderately toxic to mammals, a neurotoxin and has a high potential for bio-concentration. It is moderately toxic to birds and fish but less so to honeybees. |
