Summary: This presentation will help consultants, growers, and other practitioners control bacterial blackleg, soft rot, and stem rot in potato by providing information on how to interfere with these diseases at planting, during the growing season and at harvest. Some fundamentals of the biology and ecology of these bacterial pathogens that are related to the control of these diseases is also presented. There are no curative treatments for these bacterial diseases and no resistant potato varieties, so appropriate production practices are required to combat losses faced by these diseases. By the end of the presentation should understand why the recommended cultural practices work to control these diseases.
