Weed control challenge

Controlling cleavers, chickweed and lamb’s-quarters in cereals

Provincial weed surveys repeatedly identify cleavers, chickweed and lamb’s-quarters as a triple threat of weed concerns for cereal growers. Add to that the pressure of hard to control glyphosate-tolerant weeds and growers have serious issues to manage. With all the herbicide choices available, choosing the most effective product to control problematic broadleaf weeds on your farm can be tough.
