| | METOLCARB Usage And Synthesis |
| Description | Metolcarb (17), m-tolyl methylcarbamate
(IUPAC), C9H11NO2, MW 165.2, mp 76–77 ?C, is a colorless
solid that is moderately soluble in water and is readily
soluble in polar organic solvents. | | Chemical Properties | Metolcarb is a colorless crystalline
solid. | | Uses | Metolcarb is used to control planthoppers, leafhoppers and other
sucking pests on rice. It is also used for control of citrus mealybugs, onion
thrips, Mediterranean fruit flies, pink bollworms and cotton aphids. | | Preparation | Metolcarb is produced by the reaction between 3-
methylphenol and Metolcarb. | | Definition | ChEBI: Metolcarb is a carbamate ester. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, a carbamate insecticide, an acaricide and an agrochemical. It is functionally related to a methylcarbamic acid and a m-cresol. | | General Description | Colorless crystalline solid. METOLCARB is an insecticide for the control of rice leafhoppers, planthoppers, codling moth, citrus mealybug, onion thrips, fruit flies, bollworms and aphids. Not registered as a pesticide in the U.S. | | Air & Water Reactions | Soluble in water. | | Reactivity Profile | METOLCARB 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. | | Health Hazard | High oral and skin toxicity, and moderate inhalation toxicity. (Non-Specific -- Carbamates) Some carbamates appear to be carcinogenic, teratogenic, and/or mutagenic. Carbamates are cholinesterase inhibitors. | | Health Hazard | Highly toxic by ingestion and moderately toxic by inhalation and skin absorption; cholinesterase inhibitor; exhibits acute,delayed, and chronic toxicity; toxic effects arethose of organophosphorus pesticides and carbamate esters; the symptoms include excessive salivation, lacrimation, blurred vision,headache, labored breathing, twitches ofmuscle, loss of reflexes, headache, weakness, sweating, nausea, giddiness, vomiting,cramps, diarrhea, convulsions, and coma; U.S.EPA-listed extremely hazardous substance.
LD50 oral (rat): 268 mg/kg
LD50 skin (rat): 268 mg/kg
LD50 inhalation (rat): 128 mg/m3 hour. | | Fire Hazard | As for other solid carbamate pesticides, container may explode in heat of fire. Fire and runoff from fire control water may produce irritating or poisonous gases. Emits toxic fumes of nitrogen oxides when heated to decomposition. Avoid decomposing heat. | | Agricultural Uses | Insecticide, Acaricide: Metolcarb is an insecticide for the control of rice
green leafhoppers, plant-hoppers, codling moth, citrus
mealy bug, onion thrips, fruit flies, bollworms and aphids.
Not registered for use in the U.S. Not listed for use in EU
countries. | | Trade name | DRC 3341®; KUMIAI®; METACRATE®;
S 1065®; SOGATOX DUST® 22; TSUMACIDE®;
TSUMAUNKA®; VADEN® | | Safety Profile | Poison by ingestion and
skin contact. Moderately toxic by inhalation.
Mutation data reported. When heated to
decomposition it emits toxic fumes of NOx.
See also CARBAMATES. | | Potential Exposure | Metolcarb is an insecticide used for
the control of rice leafhoppers, plant-hoppers; codling
moth; citrus mealy bug; onion thrips; fruit flies; bollworms
and aphids. Not registered as a pesticide in the United
States. | | Metabolic pathway | The main pathways of metabolism of metolcarb in plants, mammals and
insects involve ring-methyl, N-methyl and phenyl-ring hydroxylation
and conjugation. Carbamate ester hydrolysis is a minor reaction. Further
oxidation of a ring-hydroxymethyl moiety to carboxyl occurs in rats and
insects. | | Shipping | UN2757 Carbamate pesticides, solid, toxic,
Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
UN3077 Environmentally hazardous substances, solid, n.o.s.,
Hazard class: 9; Labels: 9-Miscellaneous hazardous material,
Technical Name Required. | | Incompatibilities | Carbamates are incompatible with reducing
agents such as hydrides, strong acids, oxidizing acids,
peroxides, and bases. Contact with active metals or nitrides
cause the release of flammable, and potentially explosive,
hydrogen gas. May react violently with bromine, ketones.
Incompatible with azo dyes, caustics, ammonia, amines,
boranes, hydrazines, strong oxidizers. | | Waste Disposal | Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform to EPA regulations
governing storage, transportation, treatment, and waste
disposal. In accordance with 40CFR165, follow recommendations
for the disposal of pesticides and pesticide
containers. Must be disposed properly by following package
label directions or by contacting your local or federal
environmental control agency, or by contacting your
regional EPA office. |
