Canadian horseweed (CONYZA CANADENSIS)

The Canadian horseweed can may emerge alongside most field crops. It is a summer plant resistant to wintering, and annual. Its highest expansion level can be noticed for broad-row plantations, and among vegetables. This weed is considered to be very competitive, focusing primarily on taking over nutrients and water from the soil. Typical places, where it is found, include ruderal and roadside areas, pastures and fallow areas. A particular trait is its extensive root structure, making it resistant to mechanical control – it grows back quickly.

The Canadian horseweed develops particularly well on sandy soils. It blossoms between June and October. Its flowers are grey-white, and in bunches. The maximum plant height is one metre. Spraying by herbicides must include well-chosen products, as some biotypes of the Canadian horseweed are resistant to glyphosate.
