jap knottweed

[Johny Walker]

what legal stuff if any surrounds the control of jap knottweed in a private garden , only 2, sticks @ the mo ,

[Gary Prentice]

There was something on UKTC recently. Possible enforcement of its control under the ASBO legislation.

 

Not been used but possible. Apart from that I don't know of anything. Rob Rainford may be the man to ask.

No law against having it in your garden but a criminal offence if it spreads to neighbour.

Best get on the case with glyphosate (just been banned in Columbia for treating coca)

I think you should read the label. I'm not qualified to advise as I have an aversion to using pesticides but my understanding is that too strong a dose traumatises the plant such that it does not translocate to the roots. I'm keen on trying heat treatment.

burnt it in the past , but that was on a site job & permision to do it but had an old inspectin pit to burn it in,so well controlled

I mix at max recommended strength which is about 1litre to 15 of water then foliar spray. 1 spray will generally knock it back but may take upto three years. Our package is 3 times a year for 3 years

stem injection of glyphosate mixed 50/50 but can take three years to get rid
