Welcome to the Michigan Potato Diseases website. The goal of this website is to provide Michigan potato growers with reliable and up-to-date information on the identity, biology and disease-cycles, and current control methods for diseases of potatoes.

Due to the ever increasing number of new fungicide resistant fungal pathogens, proper and timely diagnosis of potato diseases is becoming paramount to effective disease management, and growers need up-to-date information to help make important decisions on optimal use and timing of pesticides and other control options. Most Michigan potato growers use some disease management practices, such as disease prediction models and are seeking alternative control strategies that will help them develop practical, economically viable, and environmentally sound integrated crop management systems.

This website has been setup with funding from GREEEN and is part of Michigan State University's continuing commitment to helping growers improve the way they manage their businesses, with an emphasis on integrated crop management, education, and safety.

A new series of extension bulletins on potato diseases is now in production. For the latest information see the News & Alerts page, for bulletins on foliar pathogens see the foliar diseases page, and tuber diseases see the tuber diseases page.
