Harvest conditions prompt Idaho Potato Commission to warn of tuber bruising

The Idaho Potato Commission (IPC) is advising growers that an unusually warm harvest season may lead tubers to be especially susceptible to bruising. The IPC is giving producers tips on how tuber condition can affect a crop’s chances of falling victim to blackspot bruise. Potato specialists Mike Thornton and Nora Olsen caution that heading into summer maturity varies widely between some fields, with some still immature and quite green and some are showing a good deal of natural senescence due to the unusually warm temperatures, both of which can affect tuber susceptibility to bruising. Other concerns include changes to tuber hydration when irrigation is stopped before vine kill and crop maturity at the time of vine kill. The optimal percentage of green vines to dead ones varies between varieties. More
