Chemical Description


Dinoseb is a selective non-systemic herbicide and desiccant. Dinoseb is a dark reddish-brown solid or dark orange viscous liquid, depending on the temperature and it is highly toxic.

Uses


Dinoseb is a selective non-systemic herbicide and desiccant that was used until its cancellation in 1986 on soybeans, vegetables, fruits and nuts, citrus, and other field crops for the selective control of grass and broadleaf weeds (#EXTOXNET).

Health Effects


Acute Toxicity
Dinoseb is highly toxic after ingestion in studies conducted on rats and mice (#EXTOXNET). A number of fatalities have occurred both from ingestion of dinoseb and from acute dermal exposure to workers handling it (Symptoms in persons receiving accidental exposure include fatigue, thirst, sweating, insomnia, weight loss, headache, flushing of the face, nausea, abdominal pain, and occasional diarrhea (#EXTOXNET).

Chronic Toxicity
Chronic exposure to dinoseb interferes with the production of adenosine triphophate (ATP) in the mitochondria of cells. It has also been shown to decrease birth weight and birth size in rats and to cause reproductive abnormalities in them as well (#CAL EPA).

Environmental Effects


Dinoseb is not persistent in the environment. It was widely used in central California and levels had been detected in the past in groundwater there (#CAL EPA). It is highly toxic to birds, aquatic organisms, and bees (#EXTOXNET).
