Weedkiller... is Roundup the best I can get?

[MontyVeda]

I've tried a few weed killers (all cheap) and have found that most don't do anything... I spent a little more and got some roundup which certainly kills the weeds... is it the best i can get or is there something better? (I'm asking beore I buy a large quantity of roundup). Cheers

Roundup is a lethal weed killer and very effective. Also it is very harmful (it is due to be banned in Norway before too long now).

A lot of the cheap weedkillers only kill the leaves and the root system is left, which means the weed regrows. Roundup is a glyphosphate based systemic weedkiller, ie. it kills every bit of the weed, roots included. I wouldn't use it for massive areas, rather just for spot treatment.

We had a huge Russian Vine encroaching along our fence from two houses away. I thoroughly drenched the leaves using a sprayer and an overdose of Roundup. Nothing happened for two weeks and then......Oh Boy, did it start looking yellow and sick. It died back all the way to its source. Wonderful stuff, and highly satisfying.

Its good for killing weeds on paving etc..but they will be back..

Roundup will kill the weed you put it on, although some may need repeated applications (e.g. bindweed) and it won't kill horsetail as the root system is too extensive. In block paving though, you'll still have a nice bit of soil left which new weeds will take root in.
Don't be tempted to put it on more concentrated though, you want the plant to absorb the chemical, not just scorch off the leaves.
Roundup is good for clearing an overgrown area, after that you can't beat hand weeding.

I used Roundup last year, couldn't get any at my local DiY shed a couple of weeks ago so bought some Resolva instead. It is effective much more quickly.

Roundup isn't bad, but we used gallop. Killed everything it came Into contact with. Excellent weed killer. The best we have used.

I use it at work, but very selectively. I spot spray weeds in paving and cobble stones. It is about as good as you can get, but as Dayvo says, it is potent.

Roundup is also available in a paint on gel if you only want to spot weed.

A flame throwing gun is a nicer alternative for annual weeds & top growth.

Watch out for any drift of spray. Avoid windy days and hot days.

What are you trying to kill, and where @MontyVeda ?

Agent Orange comes to mind

In used some agri-strength roundup to clear an area of land in preparation to grow a wildflower meadow. All of the conservation advisors agreed that roundup/glycophosphate herbicide was the thing to use.
Wear personal protective equipment when handling.

Gramoxone 250.

Effective - yes. WHO reckon it's carcinogenic.

Big, and long-running, arguments in the EU about whether to renew its licence or not. http://www.theguardian.com/environm...mission-glyphosate-weedkiller-leaked-proposal.

Depends what you want to kill off. For "targetted" weed kills, it's good - when I wanted to get rid of a particular weed in one spot. For clearing a large bed? Nope - tried that once years ago, and never again; took at least a season's hard work to get the soil back into good condition.

I have a particular problem with horsetails. Of course pulling them up is useless as there is always some root left behind that just regrows. Any advice as to what might be effective?

A small nuclear device perhaps?

Sorry, mate - not even a BIG one will kill horsetail

It has survived Lord knows how many global catatatrophes in its 300 million year history.
