| Application: |
Dicamba is a
benzoic acid herbicide. It can be applied to the leaves or to the
soil. Dicamba controls 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 such as fence-rows and
roadways to control weeds.
