Weeds are plants growing out of place or growing where they are not wanted. Most often weeds represent, for example, a johnsongrass plant in a cotton field. However, volunteer corn in soybeans could also be considered a weed since corn is growing where it is not wanted. Weeds scientists with the LSU Ag Center are dedicated to developing better management techniques for weeds that combine chemical, cultural, and mechanical control methods to minimize yield reduction as well as harvest efficiency problems associated with weed competition. This collaborative team approach involves both research and extension activities with the to develop cost effective and environmentally sound management strategies to help sustain agricultural production within the state.
