White powder with a faint odor. Used as a plant insecticide, acaricide, and miticide.

Hydrolyzed at pH less than 4 [EPA, 1998].

FORMETANATE HYDROCHLORIDE is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.

Extremely toxic to humans. Not absorbed through contact with skin. Inhalation or ingestion may cause poisoning. Inhibits cholinesterase activity so effects are in relation to action on nervous system and can result in death.

FORMETANATE HYDROCHLORIDE may burn but does not ignite readily. Container may explode in heat of fire. Hydrolyzed at pH less than 4

A potential danger to those involved in the manufacture, formulation, and application of this plant insecticide, acaricide and miticide.

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by follow ing package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥kg/mo) must conform with EPA regulations gov erning storage, transportation, treatment, and waste disposal.

Formetanate is an insecticide and acaricide with contact and stomach action. It is used to control spider mites and some insects (Diptera, Hemiptera and Thysanoptera) on ornamentals, fruit, vegetables and alfalfa.

Insecticide, Acaricide: Registered for use in the U.S. Not listed for use in EU countries. An insecticide used for thrips and true bug control on fruit crops.

Formetanate is hydrolysed rapidly in field and laboratory soils under aerobic and anaerobic conditions. It is metabolised by similar pathways in plants and animals. It is hydrolytically deaminated to produce a formyl derivative and subsequently hydrolysed at the carbamate ester to give a phenolic product. The phenol is deformylated to 3-aminophenol and acetylated to 3-acetamidophenol. Formetanate and most phase 1 metabolites are found conjugated. Its metabolism has been reviewed by Cool and Jankowski (1985), Fukuto (1972) and Kuhr and Dorough (1976).

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, wellventilated area.

Formetanate is hydrolysed rapidly under basic conditions. DT₅₀ values at pH 5, 7 and 9 (22 °C) are reported to be 65 days, 23 hours and 2 hours, respectively (PM). The photolysis of formetanate hydrochloride in solutions of distilled water at pH 3.1 and 7.1 or natural river water was studied. Samples were irradiated for 4 days by a high pressure Hg lamp immersed in the solutions. Light of wavelength <286 nm was filtered out. Analysis of solutions was by TLC, IR and MS. The carbamate moiety was more stable than the formamidine. Photolysis gave four products, viz. the formaminophenol (2), the 3-aminophenyl carbamate (3), the formamino compound (4) and 3-hydroxyphenyl methylcarbamate (5), a product of oxidative deamination of formetanate. Yields increased in the order given. The proposed pathways of photolysis of formetanate are given in Scheme 1 (Su and Zabick, 1972). Soil surface photolysis occurs with a DT₅₀ value of 16 hours (PM).
