What is Carbaryl?
Plain description, key identifiers and synonyms
Carbaryl is a carbamate ester obtained by the formal condensation of 1-naphthol with methylcarbamic acid. It has a role as an acaricide, an agrochemical, a plant growth retardant, an EC 3.1.1.8 (cholinesterase) inhibitor, a carbamate insecticide and an EC 3.1.1.7 (acetylcholinesterase) inhibitor. It is a carbamate ester and a member of naphthalenes. It is functionally related to a 1-naphthol and a methylcarbamic acid.

Uses and applications
What the substance is used for, by industry and function
Used in agriculture to control pests on terrestrial food crops including fruit and nut trees, many types of fruit and vegetables, and grain crops, cut flowers, nursery and ornamentals, turf, including production facilities, greenhouses, golf courses, and in oyster beds. Carbaryl is also registered for use on residential sites (e.g., annuals, perennials, shrubs) by professional pest control operators and by homeowners on gardens, ornamentals and turfgrass.
For several decades, carbaryl has been used to control burrowing shrimp on tidal mudflats in Willapa Bay and Grays Harbor, Washington. ... The available data indicate that acute mortality will likely be near 100% for animals trapped on mudflats in the immediate application area and that carbaryl will likely drift off-site with the tide.

Additionally, as part of a settlement agreement with the Washington Toxics Coalition, oyster growers on Willapa Bay and Grays Harbor have agreed to a 12-year phase-out of carbaryl use on oyster beds while they look for alternatives for controlling populations of burrowing shrimp.
Insecticide for corn, alfalfa, livestock, poultry, other non-agricultural uses (eg, home use), gardens, lawns, & for commercial/industrial use, acaricide & molluscicide.
Carbaryl is used as an insecticide on corn, soybean, cotton, fruit, nut, and vegetable crops, as well as in home yards and gardens. Carbaryl is sold under the trade name Sevin.
Use classes: Insecticides.

Pharmacology
Carbaril is a synthetic carbamate acetylcholinesterase inhibitor and suspected endocrine disruptor that is used as a pesticide. It is characterized as a toxic, white-grey odorless solid, and exposure occurs by inhalation, ingestion, or contact.
How it is made
Produced from 1-naphthyl chloroformate and methylamine or by reaction of 1-naphthol with methyl isocyanate.
In a first step, sodium 1-naphthoxide is reacted with phosgene ... and in a second step that intermediate is reacted with methylamine to give 1-naphthyl-N-methyl carbamate.
Synthesized directly from 1-naphthol and methyl isocyanate or from naphthyl chloroformate (1-naphthol and phosgene) plus methylamine.
