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.
From 2015 to 2016
Fertilizer management, Pest, weed, and disease control
At its blueberry farm (not open for pick-your-own) IRDA conducts a number of projects that benefit the sector.

An attract and kill technique to control plum curculio was recently proposed by U.S. researchers, but it is very little used in orchards and virtually unknown in Québec.

In a high density strawberry crop grown in sod covered with plastic mulch, evaluate the toxicity of bioinsecticides for controlling tarnished plant bugs and strawberry blossom beetles and of bioherbicides for controlling weeds in and between crop rows.
