Symptoms of cucurbit downy mildew on infected cucumber leaf.
Damage from previously active White Pine Weevil larvae (Pissodes strobi) has been evident for the past several weeks on Eastern white pine, Norway spruce, Siberian spruce, Colorado blue spruce, & Douglas-fir. The larvae began feeding within the terminal leaders last April. When the terminal leader is heavily infested, larvae feed side by side in a ring encircling the stem. By late spring or early summer, most White Pine Weevil larvae have pupated & emerged as adults. The terminal leader has become stunted and wilted. It is too late in the season to save the leader and it should be pruned out. To re-establish a new leader and retain the desirable Christmas tree shape read further & follow the procedures suggested.
The 2014 leader & laterals of this Eastern white pine were killed by White Pine Weevils this past spring. Photo Credit: Steven K. Rettke of RCE
