化学的特性

Fluometuron is a white crystalline solid often used in liquid solution that may be flammable.

使用

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

一般的な説明

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

反応プロフィール

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.

危険性

Toxic by ingestion. Questionable carcinogen.

健康ハザード

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

火災危険

Flash point data are not available for Fluometuron, but Fluometuron is probably combustible.

农业用途

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.

環境運命予測

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).
