A bipartisan group of U.S. Senators has urged the USDA to take additional measures to prevent the introduction of potato wart, a highly destructive disease caused by the pathogen Synchytrium endobioticum, into the U.S. The disease, which is nearly impossible to eradicate, could lead to severe economic losses for growers and the potential closure of international markets. The senators are calling for the USDA to implement stricter import regulations and more stringent measures to protect U.S. potato growers.
