US: Study warns of blackspot bruising potential during potato harvest

potatoThe accumulative impact of Idaho’s hot days, combined with warm evenings that failed to cool down, could result in blackspot bruising early in the harvest season, according to a recent study. The Idaho Potato Commission sponsored a study warning Idaho growers of preventative measures to avoid blackspot bruising of potatoes during the early harvest period. The study, published by University of Idaho potato researchers Mike Thornton and Nora Olsen, cited the crop’s “extreme differences in maturity” in the first week of September as a reason of concern for blackspot bruising. “This first part of the harvest season has been pretty warm and so again we’re just trying to make guys aware to be checking your fields and make sure they don’t get too dry,” Thornton said last week while conducting a harvest study in Bingham County.
