Chemische Eigenschaften
Fluometuron is a white crystalline solid
often used in liquid solution that may be flammable.
Verwenden
Fluometuron is an phenylurea based herbicide used on cotton and sugarcane crops.
Allgemeine Beschreibung
White crystals or powder. Melting point 163-164°C. Readily soluble in organic solvents. Used for pre- and post-emergence weed control in cotton.
Reaktivit?t anzeigen
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.
Hazard
Toxic by ingestion. Questionable carcinogen.
Health Hazard
SYMPTOMS: Symptoms of exposure to Fluometuron may include possible convulsions or coma; irritation to the skin, gastrointestinal tract, respiratory tract; and lowered blood pressure.
Brandgefahr
Flash point data are not available for Fluometuron, but Fluometuron is probably combustible.
Landwirtschaftliche Anwendung
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.

Questionable carcinogen with experimental
carcinogenic data. Mutation data reported.
When heated to decomposition it emits very
toxic fumes of Fand NOx
m?gliche Exposition
This material is used as a herbicide.
Environmental Fate
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).

Inkompatibilit?ten
Liquid solutions are incompatible with
oxidizers (chlorates, nitrates, peroxides, permanganates,
perchlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materi als, strong bases, strong acids, oxoacids, epoxides.
