The following collection of digital images is provided as a service to Arkansas agriculture. These images represent symptoms of both pathological (infectious) and non-pathological (physiological/environmental) disorders of agronomic row crops and horticultural crops that grow in Arkansas. These photos are useful as an identification tool to growers of the crops listed. Unless otherwise noted, images are furnished by Dr. Stephen Vann, Extension Plant Pathologist/Assistant Professor. Dr. Vann has compiled these photos during his tenure as plant disease diagnostician with the University of Arkansas Plant Disease Clinic. Photo credits are shown on individual photographs. Please contact Dr. Vann (firstname.lastname@example.org) for permission to use these photos for publications and presentations.
Additional images will be added as they become available.
To compliment the image library, growers may also wish to consult Extension Publication MP 154 for additional information regarding available chemical control products for various plant diseases. This publication is also available through your local county Extension office.
