Illegal plant

[baaldi]

Hi All

Just a question about weed killing of all things.

I had a visit from my local counsil to inform me I had an illegal plant growing on my land and that I had to have it removed. (No not that), The plant is called Japanise Knotweed and a battle to distroy apparently!!!

Any info would be appreciated

Cheers

Control and Treatment

If you find Japanese Knotweed (Fallopia japonica var japonica) on your land, it is your responsibility to eradicate it - kill it - and prevent it's further spread. It is no use just phoning the local council. It is your problem. You have to kill your own Japanese Knotweed. If of course, it has been bought on to your land with a load of topsoil, or other similar provable source, then you have a claim against the persons who imported it onto your land. If you are in a new build property, and suffer from the weed, then it may well be that there is a case against your builder!
Don't try composting it, this will not kill it - it is a waste of time and will lead to problems if you then use that compost on your garden!

Weedkillers and how to Kill Japanese Knotweed

No weedkillers which are persistent in the ground should be used for controlling or killing Japanese Knotweed (Fallopia japonica var japonica). The two which seem to offer the best solution in the UK are those with Glyphosate as main ingredient, or weedkillers containing
2,4-D. Glyphosate is normally sold under the brand name of Roundup, Tumbleweed or Elimin8. There are others!
If you mean business with getting rid of Japanese Knotweed, then you should invest in a good sprayer and use the concentrate form of the weedkillers, rather than the silly little Ready to Use spray cartons.

Glyphosate and 2,4-D can be used as a foliar spray - READ THE DIRECTIONS!. It will need to be applied over 2-3 years to totally kill off the Knotweed. This is a long term war, and for success you will need to win several battles!

A further method that can be adopted - though rather time consuming - is that of 'injecting' the stems with a strong solution made from the concentrate. In this case, it will need to be around ten times the recommended dilution used for spraying. It has been said that the best time for 'injection, is during the Autumn months. We disagree with this, and have seen this carried out very successfully in the full growing season. The mixture canh be directed directly into the hollows stems, but far better to cut the cane stems to around 8-10in from the ground - just below a visible joint. This will give you a hollow receptacle into which you can pour approximately your mixture - about 2-3 cm deep.

Any further re-growth - and there will be some, can then be foliar sprayed in the normal manner.

Remember, both Glyphosate and 2,3-D are weedkillers that will also kill off any of your prized plants if you accidentally spray them. The same is true of your lawn!

Alternatively, you can enlist the help of a professional weed clearance company.

Recommendations for for controlof Japanese Knotweed for contractors and building development
The costs - direct and indirect - can be quite considerable if found on building land. Directly, you can negotiate a better price or price adjustment to take into account the expense of dealing with Japanese Knotweed. You cannot simply ignore it, as a buyer or a seller. By law, Japanese Knotweed has to be dealt with. Early identification of Japanese Knotweed is essential in obtaining land for development purposes, or land that has laid vacant and is now being considered for development.

Soil which has been contaminated with Japanese Knotweed will need to be treated before it can be re used on the site for landscape or other purposes. The alternative being that untreated soil will need to go to landfill - at cost. It is essential that your staff can identify Japanese Knotweed or a consultant employed to advise. Likewise, no topsoil should be allowed on to your site until there has been an inspection of the load, and it is assessed as being free form the weed.

No, Nuclear is better -- the Fallout kills the Japanese Knotweed over a wider area......
