Oxadiazon Usage And Synthesis

Chemical Properties

Pale Yellow Solid

Chemical Properties

Colorless crystalline solid. Odorless.

Uses

A commonly used herbicide/pesticide.

Uses

Herbicide.

Uses

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.

General Description

Crystalline solid. Used as an herbicide.

Air & Water Reactions

Dust may form an explosive mixture in air.

Reactivity Profile

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.

Safety Profile

Moderately toxic by ingestion, inhalation, and skin contact. When heated to decomposition it emits toxic vapors of NOx and Clí.

Potential Exposure

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.

Environmental Fate

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 al., 1977).
Plant. Reported half-lives of oxadiazon in rice and orchard fruit are 1–2 and 3–6 months, respectively (Hartley and Kidd, 1987).

Shipping

UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required.

Incompatibilities

Dust may form explosive mixture in air. Diazo 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. This chemical is sensitive to prolonged exposure to heat. This chemical is incompatible with strong oxidizing agents.

Waste Disposal

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
