Research Projects

The aim of our project was to increase the acreage on which mating disruption is used against the codling moth in all of Québec’s apple-growing regions.

The objective of this project was to determine whether the addition of two types of organic fertilizers or biostimulants would produce more vigorous plants less subject to decline.

IRDA produced posters to help producers and extension agents choose pest and disease control strategies that promote the use of IPM.

This project helped to determine if there is a significant correlation between the number of adult spotted wing drosophila captured and yield losses observed in the field.

A cropping system based on adding organic matter through soil amendments and organic fertilizers can restore soil health and strawberry yields by limiting the occurrence of disease symptoms.

The aim of this two-year project was to determine the efficacy of various pesticides in the field.

The data generated by this project was used to develop a new NPK fertilization chart that reflects technical, agronomic, and environmental issues.

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.

This economic analysis measured the technical efficiency of Québec wild blueberry farms.

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.

This project aims to promote a biocontrol solution by testing a complex of natural enemies that attack the spotted wing drosophilia at different development stages.

The aim of this project was to field-test sound irrigation practices and band application of various types of fertilizers at ridging time to eliminate fertigation and increase the efficiency of fertilizer and water use under plastic mulch.

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.

Using sound irrigation management to control frost and water stress in lowbush blueberry helps stabilize yield while minimizing environmental impacts.

The goal of the project is to select a strain of the mullein bug to control two spotted and red spider mites when populations tend to explode.
