Weed Control in Perennial Peanut

Brent Sellers and Jason Ferrell


Perennial peanut has been called "Florida alfalfa" because it is a high-quality forage legume that performs well in tropical climates of the Deep South. Perennial peanut is highly palatable to most livestock, and bloating is not a problem as it is with many legumes. For these reasons, perennial peanut has filled a niche in the high-quality legume hay market.

In the past, weed control has been a difficult issue to overcome with this crop because very few herbicides could be used. The Florida Department of Agriculture and Consumer Services concluded that the following expanded list of herbicides can be used on perennial peanuts. However, it must be noted that this is a Florida ruling. Producers in Alabama, Georgia, or other states must check with their local regulatory agencies to ensure that these products can be used in their states.

After numerous field trials, we have compiled the herbicides that can be applied to perennial peanut without risk of adverse effects. This list contains very few products, but if used properly they should improve control of some troublesome weed species.
