Dothistroma needle blight afflicts some of the pine species commonly planted in Kentucky landscapes, particularly Austrian and Mugo pines. This disease results in brown needles, which may or may not drop from branches, and unsightly trees.
Dothistroma Needle Blight of Pine (PPFS-OR-W-25) is available online.
