Pest Alert Bur Oak Blight NA–PR–02–11

A common leafspot fungus, Tubakia dryina, was initially thought to be the cause of the blight on bur oak, but closer examination revealed a different story. Researchers in Iowa confirmed that this disease is caused by a new, and yet unnamed, species of Tubakia. The disease was named bur oak blight, or BOB for short.
