carbamates Salts or esters of carbamic acid, H₂NCOOH, or their derivatives.They include various insecticides, such as aldicarb, methiocarb, and propoxur. These are active against a wide range of insects upon contact or ingestion; they work by inhibiting cholinesterase enzymes, which are essential for nervous system function. Hence carbamates are also toxic to other animals, including humans. However, their persistence in the environment is relatively low.

carbamates A group of salts and esters of carbamic acid (H₂N.COOH) various members of which are used as insecticides, herbicides, and fungicides. They have a low toxicity to mammals, although some are harmful to non-target insects and fish, and they break down rapidly in the soil.
