Round up works too and is a systemic. My chemist-botanist friends say
that is is harmless to the environment as it dissapates within a day or
so. One professional gardener-maintenance person has told me these
grasses (weeds like bermuda grass) can grow roots 3 ft down; digging, as
you have discovered, isn't going to do it. It will even kill ivy (that
most noxious weed!), but you have to reapply it two or three times in
many cases.

Actually, I don't think the selective grass killers of this type
(ornamec,
over-the-top, poast) care which plants are monocots; I presume since
they
are post-emergent grass killers. They won't even kill sedges, much to my
dismay.
But I have been pleased with their performance in a particularly
difficult
flower border (in which I fight a constant bermuda grass battle). The
shortcomings are: of course, the chemical in the environment issue, and
that it leaves lots of ugly brown dead grass. But, hey, dead bermuda
grass
is better than live bermuda grass!! And much easier to pull out.
I tried the "sift the soil to remove the grass method" when I put in
this
bed. Spent evenings and weekends for 2 weeks sifting through by hand,
digging all the grass out, then planted and mulched. Within a month, I
was
pulling out bermuda grass again (partly from my nighbor's side of the
fence). I like the grass herbicide much better.
