In highbush blueberry fields where stunt disease has been detected, plants that have never received nitrogen fertilizer are more vigorous and homogeneous than plants that have received nitrogen fertilizer. The purpose of the exercise was to learn more about the productivity (fruit yield) of these plants, which do not appear to be affected by this pathogen.
