Farmers have voted Lamb’s Quarters the worst weed in answers to a survey by the University of Guelph.
David Bilyea, a research technician at the Ridgetown campus, worked with colleagues Kris McNaughton and Christie Shropshire to ask farmers to list the five most troublesome weeds.
Lamb’s Quarters is a common annual weed that grows up to six feet tall.
It can adapt to almost any environmental condition and is very competitive with all plants.
Others making the list are Canada fleabane, common ragweed, eastern black nightshade and pigweed.
