解説
オキサジアゾン，とくにシマジン，アトラジンはトウモロコシには殺草活性を示さないことで知られている。ダイアジン系除草剤として，ブロマシル，オキサジアゾンなどが知られ，後者は，水田のノビエなど一年生雑草，マツバイなどに有効である。ジフェニルエーテル系除草剤には，NIP(非登録)，CNP，クロメトキシニルなどが含まれ，水田における移植前後の土壌処理剤として広く使用されている。
用途
農薬(除草剤、水稲用除草剤として日本で広く用いられている。そのほかワタ、ダイズ、タマネギ等にも使用する。おもに土壌処理で、一年生イネ科、広葉雑草に有効である。)
農薬用途

反応プロフィール
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.

安全性プロファイル
Moderately toxic by ingestion, inhalation, and skin contact. When heated to decomposition it emits toxic vapors of NOx and Clí.
職業ばく露
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.
環境運命予測
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).

廃棄物の処理
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
