Canada thistle and sow thistle are the worst perennial weeds in organic field crops. Mechanical weeding methods commonly used to control annual weeds do not work on perennials. Integrated management methods for these weeds are lacking and there is very little information on their vegetative propagation and ability to regenerate under our conditions. The purpose of the project was to study the vegetative propagation and regeneration capacity of Canada thistle and sow thistle with a view to developing effective weed control strategies. The data from this study was used to identify biological behaviors that can be used in managing these perennials under Québec growing conditions.
From 2014 to 2017
Pest, weed, and disease control, Organic farming
This project will help producers to get rid of perennial weeds.

The goal of the project is to improve biological methods for controlling the cabbage seedpod weevil in canola crops. In this project, initiated by Agriculture and Agri-Food Canada and conducted in Québec by UQAM, IRDA is performing an economic analysis of the practices under study.
