text: The so-called carbamate insecticides feature the carbamate ester functional group. Included in this group are aldicarb (Temik), carbofuran (Furadan), carbaryl (Sevin), ethienocarb, fenobucarb, oxamyl, and methomyl. These insecticides kill insects by reversibly inactivating the enzyme acetylcholinesterase (AChE inhibition) (IRAC mode of action 1a). The organophosphate pesticides also inhibit this enzyme, although irreversibly, and cause a more severe form of cholinergic poisoning (the similar IRAC MoA 1b).
  Fenoxycarb has a carbamate group but acts as a juvenile hormone mimic, rather than inactivating acetylcholinesterase.
  The insect repellent icaridin is a substituted carbamate.
  Besides their common use as arthropodocides/insecticides, they are also nematicidal. One such is Oxamyl.
  Sales have declined dramatically over recent decades.
