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.

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.
