What are carbamates with examples?
Carbamates are esters of N-methyl carbamic acid. Aldicarb, carbaryl, propoxur, oxamyl and terbucarb are carbamates. Although these pesticides differ chemically, they act similarly.
Which classification of pesticides includes carbamates?
Carbamates are a class of insecticides structurally and mechanistically similar to organophosphate (OP) insecticides.
What are carbamate groups?
The carbamates are a group of insecticides that includes such compounds as carbamyl, methomyl, and carbofuran. They are rapidly detoxified and eliminated from animal tissues. Their toxicity is thought to arise from a mechanism somewhat similar to that for the organophosphates.
What is the functional group of carbamate?
carbamate ester functional group
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.
What are the classification of pesticide?
However the most common way to classify them is based on their chemical structure, identifying four main groups: organochlorines, organophosphates, carbamates, and pyrethroids.
What are the two main classifications of pesticides?

What is an organochlorine pesticide?
Organochlorine pesticides are chlorinated hydrocarbons used extensively from the 1940s through the 1960s in agriculture and mosquito control. Representative compounds in this group include DDT, methoxychlor, dieldrin, chlordane, toxaphene, mirex, kepone, lindane, and benzene hexachloride.

What is the difference between organophosphate and organochlorine?
Despite their high toxicity to the environment and to life forms, organophosphate compounds continue to be used for agricultural pest control, while organochlorines are used for vector control/disease dissemination. Moreover, such compounds are associated with occupational accidents and suicide.
Is DDT an organochlorine?
In the United States (US), the organochlorine insecticide dichlorodiphenyltrichloroethane (DDT) was first used during World War II to combat malaria, typhus, and other diseases among military populations. Widespread use began shortly after in 1945.
