CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Dicamba is a white solid dissolved in a liquid carrier. The carrier is water emulsifiable. 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. |
