Weed killer to kill grass and weeds ?

    Hi all, just wondering if someone could point me in the right direction.

    I have a big garden and rather than using the lawen mower I want to just spray certain areas that are awkward with some sort of weed killer that will just kill everything, weeds and grass etc...

    I had an empty 5L sprayer..... Will this do the job or is there better out there ? https://www.woodies.ie/roundup-500ml-bioactive-xla-1123204?nosto=nosto-page-category2

    Thanks

    boiling water will do the trick if it's just small isolated areas.

    Thanks for the reply but the area is fairly big. I'd say in total .5 acre. The straight lawns are no problem with the mower but there is a lot of bumpy and perimiter areas that I just want to bring down to the ground with nothing left.

    Yes, Roundup will do it. Three Bioactive thing is just surfactant to help it wet the leaves.

    Is Roundup linked to cancer?

    Is it safe to use if you have pets?

    Do you mean "does it cause cancer?". It's in the IARC 2A classification.
    Group 2A: "The agent (mixture) is probably carcinogenic to humans . The exposure circumstance entails exposures that are probably carcinogenic to humans."

    "This category is used when there is limited evidence of carcinogenicity in humans and sufficient evidence of carcinogenicity in experimental animals. In some cases, an agent (mixture) may be classified in this category when there is inadequate evidence of carcinogenicity in humans and sufficient evidence of carcinogenicity in experimental animals and strong evidence that the carcinogenesis is mediated by a mechanism that also operates in humans. Exceptionally, an agent, mixture or exposure circumstance may be classified in this category solely on the basis of limited evidence of carcinogenicity in humans."

    So it makes sense to use reasonable precautions when spraying (mask, gloves, minimize bare skin, don't spray when windy), but like diesel exhaust (same category) you're not going to drop dead from occasional modest exposure.

    I don't worry about pets.

    Buy Gallup 360 in a local agri store or similar it is only about €28-€35 for 5 litres of concentrate that will kill what you need it to, from grass to brambles. I bought a load last year in my local agri store for €27, you need to provide your name and address when buying it. Roundup is a rip off.

    Tend to agree. Trouble I find with Roundup? It's Not a " Weed Killer ". It's a Weed Suppressant.

    Eg. I have (Had!) a pineapple weed under my window. I've sprayed it ~ and the rest of my compound ~ religiously. Year on year. Now? After seeing it " Die ", every summer, the bloody stuff's taking over! I have a mass of the stuff beneath my window!

    Basically, Roundup just seems to tell the growth to get its head down. Shrivel up and go out of sight. But, it does Zero to the roots. So, next year, the stuff resurfaces and ye buying More Roundup to recommence battle. (KerChing! Monsanto!)

    I'm getting my brush cutter / strimmer out.

    Google Gallup 360 Ireland and you will see plenty of stores but Agri stores and Co Ops will usually have it cheapest for farmers use but you will need to give your name and address.

    Herbicides are only available over the counter in pre mixed doses to residential users. To get effective kill with something like Glyphosphate you need to use the professional grade which is or should be only available to licensed users.

    Residential doses are pretty much safe to the point of only burning the growth off. Correctly applied glypohosphate will kill most plants to the roots preventing regrowth. Some persistent weeks like bindweed, mares tail etc will need several applications or spot treatment. RoundUp, Gallup etc are retail names for the chemical.

    All asking for a PU Number (which I had to google) :(

    This stuff would fix my garden (chopped down 3 massive trees and now the sun hits a new area, weeds have devastated it, Roundup delays the weeds for a bit)

    You realise that Gallup 360 and Roundup are essentially the same, right?

    Roundup doesnt kill weeds it slightly slows them down, they come back every year.

    Google and boards suggests Gallop is a better herbicide.

    It's the same active ingredient, glyphosate.

    Killing top growth but not roots is an indicator of using the wrong concentration.

    Gallop is cheaper and boards members will nearly always recommend the cheaper option.

    Correct use of either will kill most weeds in one hit but obviously many will come back from seed. Very little glyphosate won't get rid of.


  • Registered Users, Registered Users 2 Posts: 408 ✭✭DubInTheWest


    Great info in this thread, thanks.

    I'm going to spray the weeds today. Just want to ask, how much Roundup per litre of water would you guys normally use ?

    Thanks

  • Registered Users, Registered Users 2 Posts: 2,848 ✭✭✭?Cee?view


    Understood, and thanks.

    I thought maybe there was a suggestion that a higher concentrate than on the "retail" labelling was needed.

    No, messing with the concentrations is likely to cause more problems. Roundup at high concentrations acts as a dessicant, which is one of the more obnoxious uses of it in agriculture (Google "crop dessication"). You want it translocating to the roots to kill the whole plant.

    Gallop is a generic.

    Glyphosphate is the product developed by Monsanto first marketed as Roundup. Once patent expired other companies can bring to market usually cheaper as they didn't incur development costs.

    Gallup and Roundup are exactly the same. See my original post on registered pesticide users. Retail pre mixed product is usually using 180g/ml dosage, professional rates are generally 360g/ml.

    Roundup at low concentrations is used as a desiccant - it has been used to brown out crops to speed up readiness for harvest.

    Glyphosphate as a herbicide in correct concentrations acts on plant enzymes, disrupting the growth cycle and cellular activity. That's how it is classed as a total herbicide.

    Ah, I think I'm getting mixed up with reports of people saying that excessive concentration just kills top growth without reaching the roots.

    Just pull it out after a rainy day
    Took me two years doing that 4 times a year and its all gone
    Now its a easy job for an hour to take out some of the newcomers weeds

    Spraying a high concentration of salty water will also kill off the grass (and most anything else going)

    Over the years I've used Roundup, Gallup, Touchdown and Doff (Aldi used to sell it). I use 200ml to 15 litres roughly and they they all do the trick by killing everything they land on. I've had no issue with any of them, other than the price of Roundup, doing the job and have used them mainly for paving and under hedging.
    Recently bought 5l Gallup in NI, delivered all in for €31.

    The instructions on Roundup are in a very complicated table that is aimed at agricultural users as it is in quantities of litres per acre.
    I have come to the conclusion that 250ml per litre is about right.

    LOL why bother with the water at all?

    1 part roundup to 4 parts water you must be mad.

    50ml in a liter 1 to 20 would be the highest recommended even for tough weeds https://d2j31icv6dlhz6.cloudfront.net/O/tHjlLI7bPi.pdf

    If all you are killing is grass than 10ml will do the job but 15ml is recommended.

    For normal use 25ml in a liter will kill most perennial weeds.

    About 10 times too strong!


  • Closed Accounts Posts: 5,029 ✭✭✭um7y1h83ge06nx


    That's a serious concentration alright! :eek:

    I go for 15ml per litre to clear weeds on my gravel driveway and it's never failed.

    Oops! Senior moment!

    I use a small plastic container to measure it. Just disremembered how much it holds as I haven't seen it for a while :)
    (perennial weeds, thistles ash and elder seedlings and anything that comes up in the gravel and around hedge bases.

    this is the same roundup that an agricultural worker was awarded 100million for being poisoned steadily with until he was riddled with cancer - later reduced award but still millions awarded by the courts because of the proven cancer link. Same stuff that there was a massive push to declare illegal across the EU because of its cancer causer properties & a massive court challenge by the agri industry giants because it would decimate their profits.

    No wonder with that in our watertable and soil so many are riddled with health issues.

    I tried my local glambia store for Gallup yesterday & they wanted a herd number. Do you know anywhere on line I can buy it? I've been googling it but I haven't found any without looking for herd no?

    As far as I'm aware anyone can buy roundup or Gallup without providing anything. You need a special certificate to actually use it that requires some special training course. The idea is that it is used correctly. So I'm not sure why these ask you for a herd number?

    2nd weed suppressant, these products well kill all it touches and is inert when hits ground so if you are facing annual weed infestations it's due to inert seeds or new seeds sprouting. A gardener once told me if you have garden you will have weeds, one cannot exist without the other

    Sorry I don't understand what you mean by 2nd weed suppressant?
    The area which I want to get rid of is weeds on a gravel driveway, they are ridiculously bad, it's a holy show.
    Im actually not too bothered with weeds in the grass as once it's cut it doesn't stand out.
    Is there anything else you could recommend, I've looked up remedies with vinegar but I don't know if it will be of any benefit. Thanks

    I means 2nd point. I don't know any non herbicide ways, I would just go to the co-op and buy roundup or similar and put it in strong. And remember this will be a regular job now that weeds and seeds settled

    Pull the weeds by hand. Only way to get rid if them properly. A dead weed will still leave material behind.
    Pull by hand, then spray a path weedkiller to reduce recurrence.

    It's 1:40 or 500ml in a 20l knapsack.
    400ml in 16l and so on. This is the reason the want users to do the course on pesticides. It avoids confusion on the concentrations.

    Only discovered Gallup recently and having very good results with it, even on brambles.You're right, Roundup is a rip off, you're paying for the name, it's probably one of only a very few weedkiller known by name and some can't see beyond it.

    I usually go for Gallup, Op you realize new weeds will grow and spread after you kill or pull all the old ones?
    One spray wont last a lifetime.. or a year even.

    First 5L of Gallup was €36, second months later was €37.. went in last week and they had no 5L but a 1L was €28 :confused::confused:

    Ordered on a Monday, delivered to my door on the Wednesday, €30.99 all in.

    200ml to 15l of water will kill all your typical garden weeds/grass.

    200ml to 15l of water will kill all your typical garden weeds/grass.

    Be careful using it, use rubber gloves, mask, and watch out if even a slight breeze it will carry it a few feet or more and kill anything you get it on. This is the recommended mix.
    In 10 litres of water apply Gallup 360 at the following rates:
    160 ml General use
    200 ml Annual and perennial weeds
    240 ml Perennial and broad-leaved weeds present
    Areas of use
    • Around farm buildings
    • On industrial sites
    • Pavements
    • Site preparation for landscaping, etc
    Mixing
    1.Pour the recommended quantity of Barclay Gallup 360 into
    the spray tank already half-filled with water
    2.Top up the spray tank with water to the required level
    3.Agitate thoroughly to mix the spray solution
    4.Spray out on the day of mixing
    Optimum time to spray
    • Apply at any time of the year when weeds are showing
    green leaf and actively growing. Barclay Gallup is absorbed
    through the leaves and is translocated through the weed
    down to the roots
    • A period of at least six hours and preferably 24 hours free of
    rain must follow application
    • Do not spray during frosty weather or under windy
    conditions likely to result in spray drift onto other crops,
    lawns, amenity plants or any desirable species
