Carbaryl (1-naphthyl methylcarbamate) is a chemical in the carbamate family used chiefly as an insecticide. The melting point of a solid is the temperature range at which it changes state from solid to Liquid. In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly Carbamates, or Urethanes are a group of Organic compounds sharing a common Functional group with the general structure -NH(COO- An insecticide is a Pesticide used against Insects in all developmental forms It is a colorless white crystalline solid. It is commonly sold under the brand name Sevin, a trademark of the Bayer Company. For other uses see Bayer (disambiguation or Beyer or Buyer. Bayer AG (German ˈbaɪə () is a German Originally, Union Carbide discovered carbaryl and introduced it commercially in 1958, and it remains the third-most-utilized insecticide in the United States for home gardens, commercial agriculture, and forestry and rangeland protection. Union Carbide Corporation ( Union Carbide) is one of the oldest chemical and polymers companies in the United States, currently employing more than 3800 people A garden is a planned space usually outdoors set aside for the display cultivation and enjoyment of Plants and other forms of Nature. Bayer purchased Aventis CropScience in 2002, a company that included Union Carbide pesticide operations. For other uses see Bayer (disambiguation or Beyer or Buyer.

Its safety is somewhat controversial. It is a cholinesterase inhibitor and can be toxic to humans with excessive exposure, though no known fatalities have been reported. An acetylcholinesterase inhibitor or anti-cholinesterase is a chemical that inhibits the Cholinesterase enzyme from breaking down Acetylcholine It is classified as a likely human carcinogen by the EPA. It kills various beneficial insect and crustacean species along with the pests it is intended for, so care must be taken when spraying in areas where such species are present. Carbaryl is acutely toxic to honeybees and can destroy colonies of bees that are foraging in an area where the chemical has been applied. This article refers collectively to all true honey bees for the "common" domesticated honey bee see European honey bee Honey bees

Oral LD50:
