(Also known as: carbamic acid; UC 21149; carbamyl)
SUMMARY
Aldicarb is an insecticide used to control sucking and chewing pests. It is highly soluble and volatile. It is not persistent in soil but may be in in aqueous systems. It is highly toxic to humans but has a low potential to bioaccumulate. It is a known endocrine disrupter, a neurotoxin and an inhibitor of acetyl cholinesterase. Aldicarb is highly toxic to birds and honeybees, and moderately toxic to most aquatic organisms and earthworms.
