Balsam fir tip blight
Needle, Annual shoot
Damage, symptoms and biology
Fruiting bodies develop on the needles and young shoots after they have turned from green to brown. The fruiting bodies release their spores into the air the following spring, infecting the new foliage, and the cycle starts over.
Young fir shoots wilt and shrivel, and are killed soon after they appear. The needles drop prematurely, leaving bare shoots.
