Super scrimper weed removing tip does it work??

We use a flame gun and occasionally weedkiller -both work well, better than salt

Salt works surprisingly well. I found out to my cost when i sprinkled a bit on some slugs at the base of a sunflower.
The next morning the sunflower was wilting and died very quickly.

But for a large area and long lating effects then its not the best option.

If you have a big drive, you'd be an idiot for using this technique at all. A good residual weedkiller would be the way to go. Or a flame gun, which is probably slightly cheaper than salt and a kettle.

Point is, this isn't that effective, isn't that efficient, however you do it.

Can you name one please?

And can I suggest you quit this 1, you are way off target,:D

Well, there are several commercial ones like Roundup, Resolva, and Bayer also sell one of those as a make-up-yourself solution. Gallup, available from horticultural suppliers is a cheap glyphosate solution. Bayer's Groundclear is specifically sold as a long-lasting weed killer and, at around £7 for 360metres coverage for about 6 months clearance, that's not bad. They'd all be better - in my opinion cheaper & more effective - than spreading salt and boiling water on a drive. I have Gallup and Groundclear in my shed - both seem to work well enough.

Way off target? Maybe, care to explain why?

I am saying that, as a widespread weedkiller, salt + boiling water is not as effective a solution, nor likely as cheap a solution as using a product designed for the purpose. I'm not saying it doesn't work, although there are other disadvantages like runoff.

The point was that roundup is simply a reasonably concentrated glyphosate solution, it is not residual and only kills what it is absorbed into, it's a systematic killer. It leaves no lasting residual effect.

Ok, the others I don't know about without checking, but since sodium chlorate went by the wayside, the only real residual weed killers are allowed only under licence.

Quite right DAFFY -Your getting good at this.

Hence I stated that

Bayer's Groundclear is specifically sold as a long-lasting weed killer

as it contains imazapyr, which is a real residual weedkiller...

Sodium chlorate itself never was actually very good as a residual weedkiller, it only really acts that way in tandem with atrazine, with which it was commonly sold. Sodium chlorate is extremely soluble in water, does not bind to soil, and degrades in sunlight. It would also bind strongly to iron, and hence it used to discolour paving slabs readily (which in turn pretty much degraded it to uselessness). Soil had the same effect. It's greatly mourned in its passing like so many old things that are past their use-by date, and equally useless in actual fact.

Glyphosate is, indeed, a systemic herbicide, and it too (like sodium chlorate) is degraded by soil and soluble in water. Roundup is the original name for the stuff as sold to the great unwashed. (By the way, Cb, Roundup counts as very dilute glyphosate.) It's not designated as a residual weedkiller, but since the level in soil can last anything up to six months, it certainly does have residual action, particularly if there's little rain. It's only when used at suitable low concentrations that there is likely to be little soil build-up, and no residual action.

The Bayer Groundclear also contains (I think) either flufenacet and isoxaflutole ... not sure which, as it's a while since I was last in the research lab. (These were never actually my research area, although others in my group did work on them - closest I got to it was Bt toxins back in the early 90's (and then only for a few months), and that was for killing insects, not plants... I've moved on since those days... )

So, getting back to the point? Way off target? If you say so.... but maybe we are aiming at different targets. I maintain that (salt + boiling water) is a hugely inefficient and ineffective way to treat weeds in a path or patio... fine if you have a little spare boiled water to tip by the back door... and the OP is quite correct in this.

However, even a glyphosate solution is likely to have as much residual action as a salt solution in most circumstances... not much, but some. Use a residual like Groundclear or Pathclear, and that'll work better - and cheaper in all likelihood. I'm open to correction on all the above - it's been a while since I was involved in those areas in my work and, as I said, it was never my field of expertise. I'm always willing to learn from anyone willing to post helpful advice rather than vague and cryptically critical comments.

I actually have an OLOGY In weed control and to be honest you really can't win,they will always reappear.Jim

As I said I was only commenting on your suggestion of A glyphosate based weed killer being a long term option. Roundup is one of the strongest forms of glyphosate on the market or I should say on the shelves.

Personally I use Rosate 360 that is available from the net, a very concentrated GS solution.
That one does work and I honestly had no issues re seeding an extension to a lawn, 6 months after I'd treated it heavily.
I can also add that by the time I did re seed this, new weeds and flowers where making headway

Before sodium chlorate was dumbed down it held in the ground for several years, maybe not the five claimed on the cans, but years.;)
