I didn't even know what Sevin was until I googled it. Seems like pretty potent shit -->

Applications
The development of the carbamate insecticides has been called a major breakthrough in
pesticides. The carbamates do not have the persistence of chlorinated pesticides. Although toxic to insects, carbaryl is detoxified and eliminated rapidly in vertebrates. It is neither concentrated in fat nor secreted in the milk. For the latter reasons, carbaryl is favored for food crops, at least in the US.[SUP]

Risk
Carbaryl kills both targeted (e.g. malaria-carrying mosquitos) and beneficial insects (e.g.
honeybees), as well as crustaceans.
Although approved for more than 100 crops in the US, carbaryl is illegal in several countries, including the United Kingdom, Austria, Denmark, Sweden, Iran, Germany, and Angola.[SUP]

Carbaryl is often produced using
methyl isocyanate (MIC) as an intermediary. A leak of MIC used in the production of carbaryl caused the
Bhopal disaster, the largest industrial accident in history. This accident caused around 11,000 deaths and over 500,000 injuries.
