Aldicarb sulfone
Last updated: 22/12/2020
(Also known as: aldoxycarb; aldoxycarbe; sulfocarb; ENT AI3 29261 ; UC 21865; aldicarb sulfure)

SUMMARY
Aldoxycarb is an insecticide with out approval for use in the EU. 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.
GENERAL INFORMATION
Description
An insecticide and nematicide which is the sulfone analogue of aldicarb, currently used outside the EU to control honey locust and gall midge amongst others. Can also be a pesticide transformation product
Example pests controlled
Honey locust; Gall midge; Nematodes
Example applications
Cotton; Potatoes; Sugarbeet; Ornamentals
