Title: Re: fescue and cool season grasses
Larry-I have used Poast or Select herbicide on this problem instead of Round-up in the spring and you don't have to worry about loosing any forb species even if they are up.  Generally warm season grasses are not up at this time and are unaffected.  Also these herbicides do not kill the cool season perennials, but merely set them back and give the natives a head start.  We have found it to be very beneficial.  

Once your prairie is well established (age 3 years and older) and the natives go dormate in October, consider spraying the cool season grasses like brome & fescue with Round-up in November.  This is a very effective way to eliminate them.  Don't do this on very young establishments or you will kill natives.

My wife and I planted 18 acres in the fall of 1998 (southeastern WI). In the second growing season we counted 37 species of forbs and 5 grasses (about 100 originally planted).  There are some patches of cool season grasses, none greater than 1/8 acre, and some small patches of reed canary grass.  If I were to spray these patcheswith Roundup in the next couple of weeks (april 7-21) would there be much loss of natives.  The last snow just melted and the only green I can see is grass.  I assume the little bluestem and side oats etc., won't be emerging till much later but are there any forbs at risk?
