that may be the case, but those threads are old and there may be new members with something fresh to contribute to a new thread

Roundup and mixture B, with monthly sprayings.

 

As for disposal, your talking big money as its controlled waste.

[tommer9]

Alot of it is burnt out down here, and we also have a dedicated council dept for destroying /eradicating it.

 

Having said that we are on a council farm and have a very good crop this year!!

I reckon i might start testing different control measures and report back.

[John Barleycorn]

Injection of Roundup directly into stems is recommended.

 

Do not move cut stems without a license as it is classified as hazardous waste.

[Highland Forestry]

Cut the stems at waist height, and fill them up with glyphosate..and then keep spraying!!!

 

Japanese Knotweed is a sod to get rid of, we've just managed to get rid of a small patch in a woodland site and that was with re spraying every couple of months and burning after we had killed it the first time..... the re-emergence should be sprayed as soon as it starts coming up.

 

You could use propyzamide (kerb) as well, it's residual and shuld help stop the

re-emergence.

 

Other than that..... good luck!

[Johny Walker]

cheers chaps, looks like a daunting task ahead could this be a bit a good earner ??

[Highland Forestry]

I would explain to your customer that it is in no way at all a one-visit job, and that continued treatments will be required...

It is a nightmare to get rid of... just when you think you've cracked it, it re-emerges!
