In the U.S. sweetpotato is an economically important crop with 133,000 acres planted in 2022. North Carolina is the leading producer of sweetpotato with more than 60% of the sweetpotato planted in the US in 2022. However, weed competition with sweetpotato can reduce yield and leave it susceptible to infection from pathogens and insect pressure. With a prostrate growth pattern, sweetpotato is particularly susceptible to competition for light with large broadleaf weeds such as Palmer amaranth. Meyers et al. (2010) reported as high as 81% marketable yield loss from competition with Palmer amaranth. In addition, greenhouse research conducted by Schwarz et al. (2023) reported many weed species including Palmer amaranth acting as hosts for Guava root knot nematode.
