Will Glyphosate Plus Herbicide kill Japanese knotweed?

I have Japanese Knot Weed on a few acres here and cannot find anything strong enough to kill it. Will this work or do you recommend something else?

Answer:

Glyphosate Plus does list knotweed as a target weed on the product label at a rate of 6 - 12 fl. oz. per acre.  You will likely need to use the higher rate of concentration on this weed, as this is a very tough plant, and one application of herbicide will not kill Japanese knotweed, but will only weaken it.
