Knotweed control treatment in a 3-pack kit for the eradication of Japanese knotweed, hogweed and other invasive plants. Powerful herbicides for use by professionals only. Japanese Knotweed is a hardy and invasive bamboo-like plant that can cause costly problems on construction sites and in residential gardens. Effective knotweed control requires high strength herbicidal spray treatments and excavation of the extensive root system. Due to the hardy nature of Japanese knotweed, hogweed and other invasive plants, it can often take several rounds of herbicidal treatment to fully control and erradicate the knotweeds outbreak. Roundup Pro-Biactive herbicide concentrate contains Glyphosate and is sold for qualified professional use only. Users must wear suitable clothing (coveralls), rubber boots and suitable protective gloves (not provided). Dilute at the rate of 1 part herbicide to 40 parts of water for treatment of most prenial weeds and 1 to 40 for treatment of hardy invasive plants like Japanese Knotweed and 1:20 for Ivy Here is a link that might be useful: A PRODUCT

JW has large, unlobed, heart-shaped leaves and hollow cane-like stems And does produce an aggressively creeping rootstock instead of a tight clump of growth. As an aside the common nuisance kind in some areas - including much of the Pacific Northwest and Great Britain - is Bohemian knot-weed rather than Japanese. It is an intermediate hybrid resulting from the crossing of Japanese and giant knot-weeds, with the hybrid plants often being male. So that there is not a problem with these male plants reseeding. Just covering large spaces with their vegetative growth if they are not destroyed. I have seen uncontrolled patches in my area occupying square footage the size of entire building lots - and bigger. If still nobody has done anything about it there is an infested bottom-land in the bend of a river in a National Forest east of here that may be something on the order of an acre in extent.

Thanks for sharing. Terrible stuff. I wonder if there's a way to use the fact that virtually one cloned plant has spread through G.B. to our advantage to eradicate it? One genetic type could mean one effective weakness. I've read opinions from gardening types in the past who take the stance, 'nature will evolve and adapt, this is how evolution works,' while glibly ignoring a human-driven, devastating, massive extinction of richly bio-diverse life that will take thousands upon thousands of years to reattain. Seriously, how selfish can people be? At any rate, we have a lot of work ahead of us.
