(Also known as: aldicarb sulfone; aldoxycarbe; sulfocarb; ENT AI3 29261 ; UC 21865; aldicarb sulfure)
SUMMARY
Aldoxycarb is an insecticide for the control of sucking and chewing pests. It is highly soluble in water, volatile and, based on its chemical properties, has a tendency to leach to groundwater. It is not persistent in soil systems but may be stable in aquatic systems under certain conditions. Aldoxycarb is toxic to mammals, most aquatic life and earthworms.
