Application Equipment for Potato Post-Harvest Disease Control

Late blight, caused by Phytophthora infestans (Mont.) de Bary, and pink rot, caused by Phytophthora erythroseptica Pethybr., are two devastating potato tuber diseases. These pathogens regularly cause storage losses in potato production systems. While these pathogens, especially P. infestans, spread rapidly in the field, there can also be substantial tuber-to-tuber spread during mechanical harvesting and tuber transfer procedures. With these diseases present in the field, storage losses well beyond what would be expected can occur based on the pathogen level in the field. Learn more about how to control diseases following potato harvest in this University of Maine Extension publication by Steven B. Johnson, Extension Crops Specialist.
