North America’s top potato-producing regions have been unseasonably cold and wet, something the tubers can’t tolerate.
Idaho, North Dakota and Minnesota, as well as the Canadian provinces of Alberta and Manitoba, experienced enough adverse weather from September to November to significantly affect this year’s potato harvest.
The U.S. Department of Agriculture expects the lowest yield since 2010, 22.4 million tons, a 6.1 percent decline since last year.
Frosts stunted potato growth in some regions, yielding smaller spuds overall, while snow and rain forced farmers to abandon some crops in the field. This could lead to shortfalls and rising prices.
