Blight Photos
Professor John P. Helgeson has generously shared his knowledge of late blight with the class.
With his encouragement and substantial assistance, I have edited a subset of the slides
he used to illustrate his presentation. I wish to thank both Professor Helgeson and his partner in
research, Professor Walter R. Stevenson, for their contributions.
