about £50 for 5litres if you use the generic brand. use it neat and i assure you that you'll be weed free for many months. it's even stopped the japanese knotweed coming back in my garden.

Exactly. Or you can go to B&Q and pay £40 for 220ml if you'd prefer!

HOW much for 5 litres god knows how much i would need if 20 tons of gravel didn't cover half of the driveway

Okay i'm trying the cheap illegal solutions first

if they don't work i'm off to talk to the farmer

Sodium chlorate used to be the thing for that, but the EU has now restricted the sale of it.

The people we use to maintain our garden still use Sodium Hypochlorate...we have a sandstone patio which gets algae on it. They give it a scrubbing with it about once every six months.

Not sure how they get it!

We have a Lime tree in our garden which drops this horrible sap.....makes the part of the patio under the tree black. Jet wash wont shift it but the Sodium Hypohlorate brings it up like new!

Try your local agricultural / farm supplies . I go to one in Chelford for mine , trade prices and quantities

well you're supposed to dilute it to 20ml per gallon, so i guess that would treat your entire drive a couple of times over. you use one of those pump spray things, not a watering can!

but used neat, then yeah £50 worth is what you need. that would obliterate everything.

i got my post wrong, i was diluting 600ml per gallon, so 30x recommended strength. each gallon was enough to douse a 100ftx18ft carpet of weed. i did 2 applications a few weeks apart as i have a knotweed problem. there hasn't been a single weed reappeared in the past 4mths.

Sodium chlorate is used as weedkiller.

Sodium hypochlorIte is bleach.


The ending makes a big difference in chemistry!

Sodium Chlorate is a great weedkiller. Sodium Hypochlorate/Hypochlorite is a bleach, iirc. Different stuff.

I use the 'bleach' , also from the farm supplies , diluted 2:1 and brushed on my flags / block paving. As said it kills moss and algae and brings them up like new. Far less effort and less water consumption than a pressure washer, does cut the weed growth back a little but I use the other product for that

If it's a foot thick, then maybe

weeds are tough buggers, are there many other items than can be sold with a "killer" suffix.

Well given even the domestic Roundup you'll get from B&Q works out at roughly a ml per sq m, so 540 sqm from a 540ml bottle, 5 litres will cover..... a heck of a lot more than your path.

i guesstimate he's got 300 sqm from 20T of gravel. a ml per sqm sounds a tad optimistic to me though.

Glyphosate, should be no more than £1/L

It does doesn't it, but even so, 5 litres of the stuff is going to annihilate any weeds!

Or as the next post said, Glyph would do just as well.

Ah...well they use the latter. Certainly smells like bleach. Didn't do A level Chemsitry.....and that was a long time ago anyway.

If you're a farmer no doubt. But there's a massive difference between the formulation/concentration and prices between agrochemical glyphosate and that supplied to the retail sectors. That's why it's not allowed to be sold to Joe Punter. Spill a bit of 99% water from B&Q over yourself and there's no harm done. Spill some hairy-arsed agrochem concentrate and it might be different.

You could do a few shots of neat glyphosate and you'd be fine. Its an incredibly safe herbicide and will be by far the most effective way of treating the OP's problem.

In this case you're right, but going round to Farmer Giles and carrying some home in a lemonade bottle is, well, think of the children

Insecticides are the nasty ones, which is why almost all of them have been banned in the shops and replaced with 'organic' nonsense that just makes the buggers clean!

Do they still sell thiophanate-methyl? You could eat sandwiches of that...

Glyphosate is very safe. A dilution of 60:1 works but 40:1 (25ml/litre) kills everything. It's best applied in the late spring when the plant is growing strongly and the leaves are still soft. It is not so effective in the autumn.

5 litres of the diluted spray (125ml Glyphosate) should be more than enough for a large driveway using a sprayer.
Two applications a year should be enough. Once diluted it does not "go off" so can be left in the sprayer if a top up is required.
It will take a week to 10 days to take effect and don't walk across your grass when finished unless you want an orange footprint effect. (Did it once)
