With blueberry season on the horizon, plant diseases unfortunately start to show their ugly faces. To help diagnose what disease might be affecting your plants, a handy photo guide to the common blueberry diseases in the southeast is now available thanks to our collaborators at Mississippi State University and with the support of the Southern Region Small Fruit Consortium. It's a great visual reference to help compare identifiable symptoms to what you may be observing on your own bushes. Check out the blueberry photo disease guideon Mississippi State University's extension website.

Even with the help of the photo guide, plant diseases may still be difficult to diagnose. If you aren't sure of your diagnosis feel free to reach out, look for fact sheets on some of these diseases on the NC State Extension publication website, or send samples to the Plant Disease and Insect Clinic.
