Introduction


Bentazon is a postemergence herbicide used for selective control of broadleaf weeds and sedges in beans, rice, corn, peanuts, and mint. 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 in the production of energy for survival, a process called photosynthesis. Visible injury to the treated leaf surface usually occurs within 4 to 8 hours, followed by plant death .
It should not be used on blackeyed peas or garbanzo beans. It is available as a soluble concentrate.
