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.
