2016 • Fruit production

Detecting spores of Pucciniastrum geopertianum, the fungus that causes blueberry witches’ broom rust

The aim of the project was to determine whether the witches’ broom symptom on blueberries is really caused by the rust Pucciniastrum geopertianum, which attacks balsam.

2014-2018 • Fruit production

Exclusion nets for organic apple production in Eastern Canada

The aim of this project was to test the general hypothesis that exclusion nets, when properly used, can prevent attacks by most apple pests and reduce disease incidence with no major adverse effects on fruit quality.

2017-2019 • Fruit production

Exclusion nets made from biobased polymers

The purpose of this project is to test the general hypothesis that biobased polymers can be used to replace fossil-fuel-based products and reduce the use of pesticides without increasing GHG emissions.

2015-2017 • Fruit production

Attract and kill strategies for control of the plum curculio in conventional and organic apple orchards

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.

2015-2016 • Fruit production

Productivity of healthy looking plants that have never received nitrogen fertilizer and that are located in a blueberry field infected by stunt disease

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.
