Looking for a weedkiller to kill off grass under decks. Weed fabric usually
does the job, but I want to be sure. Sodium Chlorate?

How far do they/does it spread sideways?

Weed fabric alone will be enough - cut the light off and nothing grows.
People on allotments use bits of old carpet - though I suspect your
customers may think that a bit cheap ;-

Sodium chlorate will poison the ground quite effectively - it won't spread
far though, probably a foot at the most in the wet, depending on the
strenght of application.

A Glyphosphate based killer will get in the foliage and travel down to the
roots in the same plant - but this isn't helpful in the case of grass,
though it does kill grass quite effectively.

Cheers

Engine oil? That seems to have done a bloody good job when I parked
something leaky on the "emergency parking" bit of my lawn (which has plastic
reinforcement).

Sodium Chlorate from the Pound shop. One tub should do 10m2 but I would
double the dose.

Unless you know a source for Paraquat?

Well it does but not for long.

How long does it last in the ground?

the roots in the same plant

And breaks down in the enviroment so you can use it to clear an area and
be able to replant after a while.

Chemical only treatment may not get seeds. If you don't put a fabric down
they will grow under the decking. Personally I think a decent bit of weed
fabric is all you need.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "The Medway Handyman"
saying something like:

Roundup or one its clones.

Good fabric is your best bet - kills grass dead, but there are other
plants that will happily travel several feet in the dark before
emerging. Grass normally can't compete under decks anyway, it's the
others (esp. brambles) that cause the trouble.

Sodium chlorate is easy to get hold of and works for this sort of long-
term sterilisation. Glyphosate and *quat aren't persistent enough to
be any use, although glyphosate might be useful for a first-pass to
kill things already present.

How far do they/does it spread sideways?

As far as the water goes. If there's any sort of slope with runoff,
sodium chlorate could have a run-off deadzone.

Isn't that glyphosphate based?
If so, it will only kill what's currently growing.
By design, it is deactivated when it hits the soil,
so it won't stop new plants growing afterwards.

Napalm? It is supposed to smell good in a morning.

My Aunt buys a large tub of table salt and sweeps it into the gaps,
seems to work for her, but I am not really sure because doesn't the
salt dissolve in the rain?

Only when used in conjunction with washing powder

I heard that Surf is best

yeah rondup is glyphosate. There are path clear stuffs tho. They persist
a bit longer in the soil.

Ive never found chlorate to be that effective. Except for amateur
explosives, but it isn't even any use for that these days.

Well it'll burn it off but it'll grow back. How about Agent Orange?

Well, that's what it was supposed to do, but a 5% solution of one of its
clones caused a non-growing wasteland that lasted for a year before
anything grew back at all and even then only sparsely, and it was the
only thing that killed off the briars.

Glyphosate.
