... about 5 years ago i had an infestation of japanese knotweed in my garden it had started to grow under the foundation of my garden path. we used every known weed killer and even hired a digger to get it out all to no avail. I put carcinosin 200 in a watering can out of desperation, as it was starting to grow under the house. I think I used it for 3 days. That was 3 years ago there has been no sign of it since. (189)
