A New Threat to Indiana’s White Pines
In early June a sample of a white pine was recently received at the Purdue University Plant and Pest Diagnostic Lab displaying early-season needle loss in the lower canopy. This is unusual, as most conifers retain needles for several years. The investigation revealed multiple fungi potentially contributing to needle blight or needlecast.
Common culprits, Lophodermium and Lecanosticta (brown spot), were identified. However, a more concerning pathogen was discovered: Septorioides strobi, the cause of Septorioides needle blight. This fungus, characterized by small black structures and light-colored spore horns on needles, has been linked to white pine needle damage/defoliation (WPND) in other states.
Septorioides Strobi in Indiana
While WPND has been observed in Indiana, Septorioides strobi is a new finding for us. Its impact on our climate and local pine trees remains uncertain. Like other needle blights, Septorioides thrives in humid conditions, but symptoms may not appear until the following year.
White pines are the primary target, but other pine varieties can also be affected. While Septorioides won’t likely be the sole cause of white pine decline in Indiana, it undoubtedly contributes to overall tree health challenges.
