Potato Disease Advisory 6-23-2011
Beech Anthracnose
Anthracnose has been reported on American beech in the past week. The disease starts out as a leaf spot along the veins, and spreads to large areas. Leaves start to brown completely and curl, then drop. This must have been due to a windy rain event when spores were released, resulting in severe infection on newly expanding leaves. Leaves will drop, but plants should put out new leaves during the season. The long term health of the tree should not be affected.
