During the spring of 2016, a dramatic decline of eastern white pine (Pinus strobus) has been observed throughout southern New England. MTWFA has been receiving calls and offers this link to a special report by Nicholas J. Brazee, Ph.D., Plant Pathologist at the UMass Extension Plant Diagnostic Lab on needle browning and canopy dieback of this key species. In some cases, only a few main branches are symptomatic whereas on other trees, the entire canopy exhibits the symptoms. Dr. Brazee’s article was posted in the UMass Extension Landscape Message for June 3, 2016 under Woody Ornamentals: Diseases.
