eanut weed infestation will often vary among states. However, universal weeds to all peanut production areas are the nutsedge species, specifically yellow nutsedge. Yellow nutsedge tubers are similar in size and smoothness to shelled peanut. Extension Specialists from Alabama, Florida, Georgia, Oklahoma, North Carolina, and South Carolina identify nutsedge species as being among the most common and troublesome weeds in peanut. Nutsedges tubers can lead to the greatest mass of foreign material in shelled peanut due to the similarity in size. Yellow nutsedge develops clumps of tubers that can spread and disperse with tillage. Yellow nutsedge can be prolific, producing 208 new shoots covering an area of 10 ft2 in 24 weeks from a single planted tuber.
