Chemical properties

Thiram is a type of sulfur fungicide. It has been found to dissolve completely in chloroform,

acetone and ether. It is available as dust, flowable, wettable powder, water dispersible granules,

and water suspension formulations and in mixtures with other fungicides.

Thiram is nearly immobile in clay soils or in soils of high organic matter. It is not expected to

contaminate groundwater because of its in-soil half life of 15 days and tendency to stick to

soil particles.

Acute toxicity

Thiram is moderately toxic by ingestion, but it is highly toxic if inhaled. Acute exposure in

humans may cause headaches, dizziness, fatigue, nausea, diarrhea and other gastrointestinal

complaints.

Thiram is irritating to the eyes, skin and respiratory tract. It is a skin sensitizer. Symptoms of

acute inhalation exposure to thiram include itching, scratchy throat, hoarseness, sneezing, coughing,

inflammation of the nose or throat, bronchitis, dizziness, headaches, fatigue, nausea, diarrhea and

other gastro-intestinal complaints. Persons with chronic respiratory or skin disease are at increased

risk from exposure to thiram.
