Here's an interesting article on an alternative herbicide worth
trying:

INDIANA
Sarah Adeline Kessans, 17, of Salem, studied the effects
of a
natural herbicide for her Intel Science Talent Search
botany
project. Sarah's curiosity was piqued when she noticed
that there is
little plant growth under red oak trees. She made a
natural
herbicide by soaking red oak sawdust in water for seven
days. Then
she sprayed the resulting liquid over a plot of crops and
weeds and
compared the growth of those plants with others in a
control group.
She concluded that the herbicide did not affect the
crops-corn,
wheat and soybean plants-but it did have detrimental
effects on the
three species of weeds. Sarah's research may offer farmers
an
efficient, biodegradable and inexpensive new herbicide,
especially
in Indiana where sawmills are burdened with large
quantities of red
oak sawdust. At Eastern High School in Pekin, Sarah is
president of
the Science Research Club, vice president of the French
Club,
captain of the cross country team and co-captain of the
track team.
She has earned varsity letters annually in both track and
basketball
since her freshman year and is a drummer in the marching
and concert
bands. The daughter of Timothy and Nancy Kessans, Sarah
hopes to
study botany at Purdue.

Possibly other known toxic woods such as black walnut might be
effective also.
