Plant Disease Images


The images on this website are the property of the authors and may not be used without permission. All images were taken from samples received at the University of Maine Plant Diagnostic Clinic. Where image file names begin with a nine digit number, this number refers to a specific sample entered into the PDIS database and, therefore, all images prefixed by the same number are of the same organism. Although extensive effort has been made to correctly identify the organisms in these images, this is not a taxonomic treatise and some errors may occur. Please send any corrections or other input to
