DescriptionDicamba is an herbicide used to control annual and perennial broadleaf weeds in grain crops and grasslands, and it is used to control brush and bracken in pastures. It will kill broadleaf weeds before and after they sprout. Legumes will be killed by dicamba. In combination with a phenoxyalkanoic acid or other herbicide, dicamba is used in pastures, range land, and non-crop areas (fence-rows, roadways and wastage) to control weeds. Brand names for formulations of this herbicide include Banvel, Oracle and Vanquish. (2)

Uses/SourcesDicamba is an herbicide. Dicamba controls annual and perennial rose weeds in grain crops and highlands, and it is used to control brush and bracken in pastures, as well as legumes and cacti. (2)
Minimum Risk LevelNot Available
Health EffectsIn oral, dermal, and inhaled routes of exposure, dicamba has a low acute toxicity. Dicamba may have irritating or corrosive effects on the skin and eyes. The EPA has identified dicamba as a developmental toxin in the Toxics Release Inventory. (3)
SymptomsExposing the skin and eyes to dicamba can cause redness, pain, and blurred vision. The inhalation of dicamba may cause coughing, labored breathing, vomiting, and weakness. Nausea and convulsions may also result from ingestion. (3)
TreatmentTreatment may include washing any areas of contact, GI decontamination if swallowed, administering an IV and forced alkaline diuresis. (1)
