Application: |
Bentazon is a post-emergence herbicide used for selective control of
broadleaf weeds and sedges (a weed) in beans, rice, corn, peanuts,
mint, and others. Bentazon is a contact herbicide, which means that
it causes injury only to the parts of the plant to which it is
applied. It interferes with the ability of susceptible plants to use
sunlight for photosynthesis.
