Leaf curl virus diseases have been reported in sweetpotato throughout the world. One of the causal agents is Sweet potato leaf curl virus (SPLCV) which belongs to the genus Begomovirus (family Geminiviridae). In the United States, SPLCV has been found infecting an ornamental sweetpotato and several breeding lines but not in sweetpotatoes grown for commercial production. SPLCV does not cause symptoms on Beauregard, the predominant sweetpotato cultivar in the US, but it can reduce its yield. Since SPLCV could become an important constraint for sweetpotato production; diagnosis, identification, and characterization are essential steps to develop an effective management program. The …
