What are my options to control Foxtail Barley?
Because Foxtail is a grass species it cannot be controlled with a broadleaf (selective) herbicide. To control it with a non-selective herbicide such as “Round Up” results in dead patches on the site, which in turn attracts more weeds. While fertilizer and overseeding can encourage competition from desirable grasses to help “choke out” the foxtail, it only limits new foxtail infestations and doesn’t remove existing plants. One option is to apply Kerb 50 in the late fall. This product can result in good control the following spring, but is dependent on soil moisture conditions.
