Field bindweed is a deep-rooted perennial weed that severely reduces crop yields and land value. This noxious weed is estimated to infest just under 2 million acres and is found in every county in Kansas. Bindweed is notoriously difficult to control, especially with a single herbicide application. During the fall, but prior to a hard killing freeze, can be an excellent time to treat field bindweed – especially in a year when good fall moisture has been received. This perennial weed is moving carbohydrate deep into its root system during this period, which can assist the movement of herbicide into the root system.
