Research Projects

IRDA drew up a list of insects and mites in Québec known to be or likely to become resistant to pesticides.

As part of an integrated pest control program, the company Les Serres Rosaire Pion & fils launched an innovative project on the use of flower strips in potted perennial production.

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 series of herbicides has been tested along the edge of the plastic mulch.

This project proposes ways of using legume intercrops to control vegetable pests (insects, diseases, and weeds) while increasing soil productivity and quality and economic yields.

This project as aimed at comparing the efficacy of two parasites (T. brassicae and T. ostriniae) on leek moth.

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

This project evaluated effective and economically viable control strategies for swede midge that are healthy for both humans and the ecosystem.

This project determined the efficacy of various pest control products on the striped cucumber beetle on organic cucurbit crops.

This three-year project looked at optimal ways to use a mix of flowering plants against caterpillar pests of crucifers.

Biofumigation could be an attractive option for increasing the mortality of dormant seeds.

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.

The fungal pathogen Helminthosporium solani causes silver scurf, a disease that is hard to detect, both in the soil and on harvested potatoes.

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.
