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. Weed scientists with the LSU AgCenter are dedicated to developing better management techniques for weeds that combine chemical, cultural, and mechanical control methods to maximize yield and reduce harvest efficiency problems. This collaborative team approach involves both research and extension activities with the goal to develop cost effective and environmentally sound weed management strategies to sustain agricultural production within the state.
