| Hazard Information | Back Directory | [General Description]
Crystalline solid. Used as an herbicide. | [Reactivity Profile]
OXYDIAZON(19666-30-9) 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. | [Air & Water Reactions]
Dust may form an explosive mixture in air. | [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. | [First aid]
If this chemical gets into the eyes, remove any
contact lenses at once and irrigate immediately for at least
15 minutes, occasionally lifting upper and lower lids. Seek
medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions) if
breathing has stopped, and CPR if heart action has stopped.
Transfer promptly to a medical facility. When this chemical
has been swallowed, get medical attention. Give large
quantities of water and induce vomiting. Do not make an
unconscious person vomit. Do not induce vomiting when
formulations containing petroleum solvents are ingested | [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. | [Chemical Properties]

Pale Yellow Solid | [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 | [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. | [Definition]
ChEBI: Oxadiazon is an aromatic ether. | [Trade name]

GOLD KIST®; PAR EX®; PRO GROW®; REGAL
O-O®; REGALSTAR®; RONSTAR®; RP-17623®;
TURFIC®; VERTAGREEN®; WILBRO | [Safety Profile]
Moderately toxic by ingestion, inhalation, and skin contact. When heated to decomposition it emits toxic vapors of NOx and Clí. | [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). |
