Oxadiazon Usage And Synthesis
Pale Yellow Solid
Colorless crystalline solid. Odorless.
A commonly used herbicide/pesticide.
Preemergence herbicide used for controlling certain annual grasses (e.g., bluegrass, barnyardgrass, crabgrass, goosegrass, sprangletop) and broad-leaved weeds (e.g., cudweed, dayflower, filaree, groundsel, jimsonweed, morningglory, mustards, pigweed, redmaids, smartweed, sowthistle, velvetleaf) in turf, lawns, orchards and ornamentals.
Crystalline solid. Used as an herbicide.
Air & Water Reactions
Dust may form an explosive mixture in air.
Oxadiazon is a diazo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Moderately toxic by ingestion, inhalation, and skin contact. When heated to decomposition it emits toxic vapors of NOx and Clí.
An oxadiazolinone/oxidiazole preemergence and early postemergence herbicide used to control annual grasses, sedges, and broadleaf weeds. Originally registered for use on turf and ornamentals; has wide use on golf courses.
Soil. The reported half-life in soil is approximately 3–6 months (Hartley and Kidd,
1987). Oxadiazon degraded slowly in both moist and flooded soils. After 25 weeks, only
0.1–3.5% degraded to carbon dioxide and 0.5–1.1% as volatile products. Metabolites
identified included oxadiazonphenol, oxadiazon acid and methoxyoxadiazon (Ambrosi et
Plant. Reported half-lives of oxadiazon in rice and orchard fruit are 1–2 and 3–6 months, respectively (Hartley and Kidd, 1987).

Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. This chemical is sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents.
It is the responsibility of
chemical waste generators to determine the toxicity and
physical properties and of a discarded chemical and to
properly identify its classification and certification as a hazardous
waste, and to determine the disposal method. United
States Environmental Protection Agency guidelines for the
classification determination are listed in 40 CFR Parts
261.3. Additionally, waste generators must consult and follow
all regional, national, state, and local hazardous waste
laws to ensure complete and accurate classification and disposal
methods. Follow recommendations for the disposal of
pesticides and pesticide containers. Containers must be disposed
of properly by following package label directions or
by contacting your local or federal environmental control
agency, or by contacting your regional EPA office.
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed, incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environment
