Scouting for abiotic diseases: Fall needle drop

Editor’s note: This article is from the archives of the MSU Crop Advisory Team Alerts. Check the label of any pesticide referenced to ensure your use is included.

It is normal for evergreens to lose their interior needles in the fall. Loss tends to be more pronounced during years with dry weather. It is not normal for needles to drop from the current year’s growth, or to drop in the spring or summer. Check for another cause such as salt injury, a disease problem, frost, or drought if this occurs.

The information is from A Pocket IPM Scouting Guide for Woody Landscape Plants. For ordering information, please visit: http://www.emdc.msue.msu.edu/ or call the MSU Bulletin Office at 517-353-6740 and ask for inventory number E2839.
