White crystals or powder. Melting point 163-164°C. Readily soluble in organic solvents. Used for pre-and post-emergence weed control in cotton.

FLUOMETURON is a trifluoromethyl urea derivative. May react with hypochlorites to form nitrogen trichloride which explodes spontaneously in air [J. Am. Chem. Soc. 63:3530-32]. May reacts with azo and diazo compounds to generate toxic gases. Reacts with strong reducing agents to form flammable gases.

Toxic by ingestion. Questionable carcinogen.

SYMPTOMS: Symptoms of exposure to this chemical may include possible convulsions or coma; irritation to the skin, gastrointestinal tract, respiratory tract; and lowered blood pressure.

This material is used as a herbicide.

Flash point data are not available for this material, but FLUOMETURON is probably combustible.

Skin Contact: Flood all areas of body that have contacted the substance with water. Don’t wait to remove contaminated clothing; do it under the water stream. Use soap to help assure removal. Isolate contaminated cloth ing when removed to prevent contact by others. Eye Contact: Remove any contact lenses at once. Flush eyes well with copious quantities of water or normal saline for at least 20 30 minutes. Seek medical attention. Inhalation: Leave contaminated area immediately; breathe fresh air. Proper respiratory protection must be supplied to any res cuers. If coughing, difficult breathing or any other symptoms develop, seek medical attention at once, even if symptoms develop many hours after exposure. Ingestion: Consult a physician, hospital or poison center at once. If the victim is unconscious or convulsing, do not induce vomiting or give anything by mouth. Assure that the airway is open, lay on side and keep head lower than body and transport immedi ately to medical facility. If conscious and not convulsing, give a glass of water to dilute the substance. Do not induce vomiting without a physician’s advice.

Fluometuron is an phenylurea based herbicide used on cotton and sugarcane crops.

Herbicide used to control many annual broad-leaved weeds in sugarcane and cotton

Herbicide.

ChEBI: Fluometuron is a member of the class of 3-(3,4-substituted-phenyl)-1,1-dimethylureas that is urea in which one of the nitrogens is substituted by a 3-(trifluoromethyl)phenyl group while the other is substituted by two methyl groups. It is a herbicide used for the control of broadleaf weeds and annual grasses in cotton. It has a role as an agrochemical, an environmental contaminant, a herbicide, a xenobiotic and a photosystem-II inhibitor. It is a 3-(3,4-substituted-phenyl)-1,1-dimethylurea and a member of (trifluoromethyl)benzenes.

Nonflammable

Herbicide: A General Use Pesticide (GUP). Fluometuron is a selective herbicide which acts on susceptible plants by inhibiting photosynthesis. Fluometuron is registered by EPA exclusively for use on cotton and sugarcane. It can be applied pre-emergence, for weed control before planting, or post-emergence, after target crops and weeds come up, and may have residual activity for several months. Fluometuron is available in liquid, dry flowable, and wettable powder formulations.

Soil. In soils, ?uometuron rapidly degrades (half-life approximately 30 days) to carbon dioxide, polar and nonextractable compounds (Hartley and Kidd, 1987; Humburg et al., 1989).
Groundwater. According to the U.S. EPA (1986) ?uometuron has a high potential to leach to groundwater
Plant. In plants, ?uometuron degrades to a demethylated intermediate which subsequently is degraded to the aniline moiety (possibly m-tri?uoromethylaniline) (Hartley and Kidd, 1987; Humburg et al., 1989). Duke et al. (1991) reported that ?uometur
Chemical/Physical. Emits toxic fumes of nitrogen oxides and ?uorine when heated to decomposition (Sax and Lewis, 1987).

Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in a refrigerator or a cool, dry place and protect from exposure to ultraviolet light. Keep liquid awayfrom oxidizers. Where possible, automatically pump liquidfrom drums or other storage containers to processcontainers.
