Can you be specific about how this species is becoming a problem? Is it because of its invasive nature to infrastructure (sidewalks, driveways, curbs), or to farmers and gardeners, or to nature lovers?
Invasive species have interested me since I was a little kid, and was appalled at the thousands of alewife (a small ocean fish) carcasses on the Lake Huron beach near my hometown.
Thanks.

Japanese Knotweed is a major problem as an invasive due to the fact that it is very hard to remove mechanically, negatively impacts riparian habitats, and crowds out negative vegetation. The plant can even survive temperatures as low as -30F. One of the best methods of control is to use a very targeted herbicide application during the fall flowering state of the plant.
Mechainical removal is highly recommended if possible, though. |

...so that's what I have growing on my leach field. Grows incredibly fast; I mow it to the ground anytime I see leaves which seems to have reduced its quantity after 2 years of doing so.
Any issues with spraying said herbicide over leach field?
Edit: So mine looks like the knotweed in this picture: http://en.wikipedia.org/wiki/File:Knotweed.JPG; but not the others...and I've never seen flowers on it. |

I have had better luck using the targeted herbicide recommended by wikipedia as well as other website sources. Some sources say that mowing it could cause knotweed to regenerate and spread more quickly. I have helped neighbors mechanically remove knotweed and that has largely worked. The flowering state typically occurs during mid-fall but not always. It is easily identifiable during the summer due its growth in clumps and larger leaf size. |
