Do you recommend Surflan AS Herbicide as a pre-emergent for foxtail barley in my pasture grass?

Some information I have read for foxtail says to apply the herbicide this fall and some say to apply it next spring. When do you suggest I apply it? I live in Grand Junction, CO. (Elev. 4800 ft.) where there are late Falls and early Springs. The pasture is a wheat grass and some orchard grass.


Surflan AS is a great pre-emergent and will work on foxtail as well as many other broad leaf weeds, but is not labeled for use in pastures.  Most pre-emergents should be applied in both the Fall and early Spring.  It varies depending on where you live and climates where you live.  We recommend contacting your local county extension office as they should have the most accurate information on how and when to treat weeds and insects in your local area, as well as the best advice on what to use in a grazing pasture.
