Diquat is a contact herbicide used also to produce desiccation and defoliation. (From Merck Index, 11th ed)
Diquat is a yellow crystalline solid dissolved in a liquid carrier. It is a water emulsifiable liquid. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It can cause illness by inhalation, skin absorption and/or ingestion. It is used as a herbicide.
