Black Shadow is a relatively new disease issue facing some NJ blueberry growers. One grower started applying Sulforix last spring at 1 gallon/acre to help control Black Shadow. A second application was made about two weeks ago to the same treatment area. These photos are from his treated and non- treated areas yesterday. The farm manager commented that he can tell an instant difference when looking at the field as a whole in the coloring without black shadow.
