dc.description Canadiaan Thistle, a perennial, was one of the seven most common weeds in wheat crops in North Dakota in 1978/79. It takes only 2 Canadian Thistle plants per square yard to reduce wheat crop yields by 15%. It's root system is extensive, spreading out and going deep. Glyphosate did reduce this menace. However, it was deemed more effective on sparse densities of this weed. It's effectiveness was most effective for one season. The changing environment factored into the effectiveness of the herbicide application.
