Currently, the images seen in this assemblage originated as part of a shared teaching collection of slides. Most images were created by members of the University of Minnesota's Plant Pathology community who were active primarily during the second half of the 20th Century. Detailed credit information and rights ownership is unclear for many of the images in the collection. If you have such information about any of these images, we'd love to hear from you! They are shared here in the spirit of those who created and collected them, in hopes of enabling teaching and inquiry by others.
