From another thread, I learned of Hi-Yield Grass Killer at Ace Hardware.
I applied it all over my "back 40," which was covered in stilt grass
waist high. I sprayed for nearly 2 hours and used most of the quart,
also around $35, mixed exactly as recommended. Of course, this was
last resort after pulling the grass since Sept 2001, when Colin Powell
urged us to rip out terrorism by the root wherever we found it, and
which I executed on the backyard invader I have come to call the
"Tali-bamboo."

Taunting me with martinis from the deck, my husband laughed at what we
both believed to be a futile final assault. For two weeks after, I did
not see the greeny robustness of the weed but neither was it dead. But
after a 2 week vacation, I returned to a field of DEAD stilt grass--I
mean, DEAD AS A DOORNAIL DEAD. A month later I got around to raking up
15 bags of stilt grass hay, and I did not see a living leaf.

I applied the grass killer when no rain was forecast for a week because
I did not want it to go into our creek. It killed nothing else around
it; it's a wild area, mainly vines. I am planning to reapply as soon
as it starts poking up next year and as needed after. I have spent so
many hours on this grass that an hour or two of spraying is nothing,
and if it does get out of hand again, I won't have either the
hand-pulling or raking to repeat either.

This grass showed up after Hurricane Fran, when this area was scoured
by the over-flowing creek. I called it "hurricane grass" when it first
came up. My neighbor thought it was great looking and still does. It's
an easy-to-grow lawn, as far as he is concerned, and he just mows it.
