For the past 50 years, areas near the border between North and South Carolina have been ground zero for a fierce battle in the war against a devastating weed. Federal and state officials and local farmers have been fighting the only known U.S. infestations of witchweed (Striga asiatica), an invasive plant that has crippled key segments of the agricultural industry in countries around the globe.
