New Disorder of Spruce in Illinois: Sudden Needle Drop of Spruce (SNEED)

/Home/Garden Basics/Trees/Tree Diseases/Spruce Tree Diseases/Spruce Tree Sudden Needle Drop Disease

The University of Illinois Plant Clinic has received spruce samples from both central and northeastern Illinois that have been diagnosed with Sudden Needle Drop (SNEED) caused by Setomelanomma holmii. While SNEED has been found in several surrounding states, this is a first find in Illinois. We are pursuing independent identification since this is a first find as well as proceeding with qPCR analysis for verification.
