Research Projects

Each year, IRDA's R&D Team conducts more than one hundred research projects in sustainable agriculture. What's more, IRDA is working with Quebec's key agricultural stakeholders to find concrete solutions.

Strawberries
2016-2017 • Fruit production

Adding organic matter and biostimulants to restore and maintain soil health and yields in a matted row strawberry field with a history of decline

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.

Researcher: Christine Landry

Poster
2016-2017 • Fruit production

Posters on integrated fruit production for strawberry, raspberry, and highbush blueberry crops

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

Spotted wing drosophila egg
2015-2017 • Fruit production

A study on the link between spotted wing drosophila populations, crop damage, and yield losses

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.

Strawberry field
2015-2017 • Fruit production

Developing a cropping system that focuses on improving soil health to restore the yield potential of matted row strawberry fields with a history of strawberry decline

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.

Blueberries
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.

Researcher: Richard Hogue

Exclusion nets
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.

Researcher: Gérald Chouinard

Spotted Wing Drosophila
2016-2019 • Fruit production

Control strategies to reduce the impact of the spotted wing drosophila

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.

Researcher: Annabelle Firlej

Exclusion net
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.
