A postemergence bis-carbamate herbi- cide used on sugarbeets to control annual weeds such as pigweed, wild mustard, lamb’s quarters, nightshade, chick- weed, buckwheat, goosefoot, ragweed, fiddleneck, and kochia

Speed in removing material from eyes and skin is of extreme importance. Eyes: Eye contact can cause dan- gerous amounts of these chemicals to be quickly absorbed through the mucous membrane into the bloodstream. Immediately and gently flush eyes with plenty of warm or cold water (NO hot water) for at least 15 minutes, occa- sionally lifting the upper and lower eyelids. Get medical aid immediately. Skin: Get medical aid. Dermal contact can cause dangerous amounts of these chemicals to be absorbed into the bloodstream. Wearing the appropriate PPE equip- ment and respirator for carbamate pesticides, immediately flush skin with plenty of soap and water for at least 15 min- utes while removing contaminated clothing and shoes. Shampoo hair promptly if contaminated; protect eyes. Ingestion: Call poison control. Loosen all clothing. Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious, alert, and able to swallow, rinse mouth and have victim drink four to eight ounces of water. Check to see if poison con- trol instructs you to use ipecac syrup, otherwise administer slurry of activated charcoal (2 oz in 8 oz of water). If vic- tim is UNCONSCIOUS OR HAVING CONVULSIONS,do nothing except keep victim warm. In some cases you may be specifically instructed by poison control to induce vomit- ing by way of two tablespoons of syrup of ipecac (adult) washed down with a cup of water. Do NOT give activated charcoal before or with ipecac syrup. Inhalation: Get medi- cal aid. Do not contaminate yourself. Wearing the appropri- ate PPE equipment and respirator for carbamate pesticides, immediately remove the victim from the contaminated area to fresh air. If the victim is not breathing, administer artifi- cial respiration. Do not use mouth-to-mouth method if vic- tim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. If breathing is difficult, administer oxygen through bag/ mask apparatus until medical help arrives. Do not leave victim unattended.

UN2757 Carbamate pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Esters with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interac- tion of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. Carbamates are incompatible with reducing agents, strong acids, oxidizing acids, peroxides, and bases. Contact with active metals or nitrides cause the release of flammable, and potentially explosive, hydrogen gas. Forms Carbon monoxide and toxic nitrogen oxides when heated to decomposition.

Colorless, crystalline solid.

Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guid- ance on acceptable disposal practices. Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.

[3-[[(Phenylamino)carbonyl]oxy]phenyl]carbamic acid ethyl ester  is a carbanilate based herbicide used in the weed control programs in sugar beet.

Desmedipham is a carbanilate based herbicide used in the weed control programs in sugar beet.

Selective systemic herbicide used to control broad-leaved weeds such as buckwheat, chickweed, fiddleneck, kochnia, mustard, pigweed and ragweed.

ChEBI: A carbamate ester that is phenylcarbamic acid in which the hydrogen of the hydroxy group has been replaced by a 3-[(ethoxycarbonyl)amino]phenyl group. It is an agrochemical used as a herbicide.

Soil. Degrades in soil forming the intermediate 3-hydroxycarbanilate (Worthing and Hance, 1991). The reported half-lives in soil are 70 days, 20 hours and 10 minutes at pH values of 5, 7 and 9, respectively (Worthing and Hance, 1991).
Plant. In sugar beets, m-aminophenol and ethyl-N-(3-hydroxyphenyl)-carbamate were identified as metabolites (Hartley and Kidd, 1987).
