Did a google search and came up with the following.
The easiest way of erradicating bamboo is to use sodium clorate.
It's the only (and i mean only) chemical that kills it effectively.
Just spread the chemical (looks like sugar or salt) evenly around the growing area, so that it can be absorbed by the roots.
Like fertilizer.
Depending on the size of the area covered, between 100-300 gram is neccessary for one
"bamboo bunch".
Another way which uses less off the chemical, is to clearcut the bamboo first.
Then when it re-sprouts (and has a few leaves), mix sodium clorate at the rate of 100 gram per liter and spray all the green parts, including the leaf and stem of the new shots.
It might be neccessary to repeat this treatment once if it re-sprouts, but I have never had to have done this more than two times.
I have experience with these things as i'm an oil palm plantation owner in southern thailand.
In here, bamboo is mostly considered an unwanted plant.
Bye bye bamboo
