Weed Killer- the daddy?

Alternatively, find your local farming supplies place and buy 5l of 360g/l RoundUp for about £45+VAT and dilute it yourself down to the strength you need - which is proportionately around a third of the cost of even the Verve Tough Weedkiller (and means you'll probably never need to buy weedkiller again).

It seems the ammonium sulphamate link on page 1 is still on sale...

I've put some down on my chipped area round the front and nothing seems to be growing any more. All I could find about dosage was 1kg per 5 litres but I didn't realise how quickly that disappears from a watering can.
ETA: Any difference between Sulphamate and Sulphate?

My worry would be how much went down the storm drain and straight into the nearest watercourse.
Surely at that point it will be instantly diluted and have the same effect as if the guy had diluted it?These incidents can have serious effects - glyphosate not so much as this, it's harmful to the aquatic environment but the damage is more subtle, but this kind of incident can occur;

Yes - sulphamate is weedkiller and sulphate is fertiliser.http://en.wikipedia.org/wiki/Ammonium_sulfamate

Two letters in chemistry make a lot of difference!

Thanks for the links though, I'm now a happy idiot.

Oops... My next door neighbour has just been spraying his block drive too kill the weeds. I asked him what he was using, and showed me a 5l bottle of glyphosate he's asked a farmer to get him, down to the last litre. He then said it doesn't go far, he didn't think 5l was enough.
I then suggested he read the instructions....
200ml weedkiller to 9,800ml water. He'd been using it neat!
For those that don't know, a typical application rate for "roundup" is 4 litres per hectare, so 5 litres could treat 12,000 square meters. I then suggested he read the instructions....

As commercial weedkiller doesn't seem to be touching the stuff that's coming through the shingle, I'm going to get some of this now

The only thing that's stubborn with this is moss on my blocked driveway. Chips are still nice and dead though.ETA: Any difference between Sulphamate and Sulphate?

I've got lots of this Xmas tree weeds (horse tail) I think they can be 5m of roots connected underground
So what is the best thing to kill it off permanently?
1) table salt
2) ammonium sulphamate (seen on amazon for about £14)

You need something systemic that gets down to the roots, and glysphate is best for that. Ideally you want to do it in the spring when the plant is growing, might get away with it now, but dont leave it much longer. Also you'll need to spray again in the spring I expect.
Nothing with 5m roots and which is as prolific as horse tail will be easy to kill in one go.

Market segmentation... special 'low temperature' weedkiller with a picture of Santa Claus on the label.I worked in the industry y'know
Not sure about your weeds, but winter doesn't seem to phase mine.
