Description

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.

Objective(s)

  • Improve knowledge about the role of nitrogen fertilizer in the expression of stunt disease symptoms and the productivity of blueberry fields
  • Improve knowledge on the impacts of blueberry stunt disease on fruit yield and eating quality
  • Educate industry stakeholders about this pathogen and its impacts on blueberry fields

From 2015 to 2016
