Aldicarb is a carbamate insecticide which is the active substance in the pesticide Temik. It is effective against thrips, aphids, spider mites, lygus, fleahoppers, and leafminers, but is primarily used as a nematicide.[1] Aldicarb is a cholinesterase inhibitor which prevents the breakdown of acetylcholine in the synapse. In case of severe poisoning, the victim dies of respiratory failure.
Aldicarb is one of the most widely used pesticides internationally, and is also one of the most environmentally toxic. Aldicarb poisoning from agricultural water runoff has led to the destruction of healthy ecosystems and the irreversible poisoning of fertile agricultural land. Poisoning from this pesticide is also believed to be linked to high cancer rates in communities located around the Aral Sea.
