Avoid harvesting potatoes with pulp temperatures less than 45°F. For varieties susceptible to Fusarium dry rot (for example Clearwater Russet, Umatilla Russet) it is recommended to harvest at pulp temperatures above 50°F. Cold temperatures increase the potential for potatoes to shatter bruise or fissures to occur and thus allow a perfect entry point for Fusarium dry rot or other pathogens to invade. Shatter bruises are also more difficult to wound heal due to the jaggedness of the wound. The damaged surface area of a potato can lose up to 500% more water compared to an undamaged area.
