Brunnings 1 Hour Fast Action Weed Kill is a fast action, ready to use herbicide that gives users the highly visible results within 1 hour, while going on to kill the weed, roots and all.

• Strong results visible within 1 hour on most weeds

• Rainproof after 30 minutes

• Kills weeds and grasses, roots and all

Active constituents:
16g per 1 L of glyphophosphate present as ammonium salt
25g per 1 L of nonanoic acid

As a comparison, fast action Roundup has pretty much the same ingredients and is $21 for the same size….

  Is it really that fast? Nonanoic acid is a pretty strong acid then. I've tried sulphamic acid, it's hit and miss.

  In regards to Weed Killers, just be careful of what they contain, there was a recent news article about round-up and the lack of safety precautions Aussies are taking when using it.

    Many weed killers use Glyphosate as their active ingredient, which has been linked to potential cancers, at least in the United States a greens-keeper at a school developed lymphoma, who then subsequently sued the manufacturer of the chemical, who I think at the time was Monsanto and won his case, I think.

    There are both sides of the coin, with studies demonstrating that Glyphosate is perfectly safe, and that Glyphosate is extremely dangerous as a likely carcinogen.

    It’s also worth remembering that Monsanto developed seeds that were genetically modified in order to be grown in conjunction with the administration of a regimen of Roundup weed killer, which would kill pests but not affect the plants. Similar to various types of grass weed killers that don’t kill the grass but kill weeds.

    So a question at least in my mind is how much of what we routinely eat in restaurants, or at home, or in schools etc is affected by exposure to Glyphosate? Not to mention exposure to things like DDT, which are residual and can remain active for years in soil?

    Farmers, or in the case of the greens keeper, had prolonged, repeated, and intensive exposure to Glyphosate, and presumably other chemicals, which potentially significantly contributed to their development of various types of cancer, and on-going DNA damage.

    It’s similar to instances of asbestos exposure where it’s likely that people who develop various forms of lung, and throat cancers associated with exposure likely had instances of prolonged exposure to asbestos fibres, and likely had additional comorbidity, such as smoking.

    I’m not saying that only people with extended exposure to Glyphosate will develop cancer, but I’d suggest for many people not to worry about previous exposure as a definite link to cancer but, as you say, take relevant precautions when using it.

    More and more cases are being brought against Bayer (who now owns Monsanto), and Monsanto for culpability over the link between Glyphosate and cancer.

    But my real worry is how much of the stuff is likely in our food supplies.

    Certainly Monsanto doesn’t have a good reputation, having developed chemicals such as agent orange, notable for the orange coloured barrels it was shipped in to Vietnam during the Vietnam war and used as a defoliant which is now believed to be a significant contributor to birth defects and cancers in Vietnamese populations as well as health affects on US servicemen who served during the conflict.

      and won his case, I think

      Yes, that's what I heard as well, but I'm 90% sure Monsanto/Beyer were appealing the ruling.

      There's some recent news in France where a mayor of a town tried to ban pesticides.

      A mayor in north west France is to appear in court on Thursday after banning the use of pesticides near homes in his village in a case that is seen as emblematic of rising opposition to chemical pollution in rural areas.Source

      I heard a report from RT about this a few days ago where one of the residents said she had only consumed local organic produce, but her family still had pesticides show up in their urine samples. So there's a lot of contamination via wind, it seems.

        "Organic" doesn't mean no pesticides. To that end, organic pesticides aren't necessarily safer than synthetic ones, either.

        Urgh. That’s not great. Makes me wonder how much stuff I’ve eaten over the years that’s accumulated. I prob shouldn’t think about it.

        I’d heard about the pesticides in France as well, but I have a feeling that it was to do with Fipronil, which is a type of fungal transmitting pesticide that’s affecting bee populations. It’s used a lot for ants, and it spreads between the colony, but I guess (I’m not sure) that maybe the bees transfer it between each other, and it’s knocked out a lot bee populations. It’s residual I think for around 5-10 years, in ideal conditions, so I guess hopefully exposed to weather if they stop using it they might be able to bring the bee populations back up. But I mean ideally yeah less pesticides would be a good thing I think too.

      Don't breathe it in or get it on you. This bloke did neither. At this diluted rate which is for domestic sale (30 times weaker then commercial) you'll be fine.

    This is not a residual herbicide but a post emergent systemic herbicide. You will struggle to find a pre emergent herbicide on the domestic market, given that the longest control I can get commercially is 6 months using a product called barricade.

  Combining a systemic herbicide with a contact knock down (the acid) is dumb. The plant will defoliate, preventing the slow moving systemic herbicide to do its job. The result being that the roots are not killed, especially with dicots like flat weeds etc.

        Thanks for your input on this thread.

        Can you offer any advice on killing off winter grass now, given that I've missed the opportunity to get a pre-emergent on it back in May!

          maxwellish on 11/09/2019 - 06:26

          @Qbagger: Wintergrass is very hard to kill. What is your base turf?

          Products like Tribute and Monument are quite effective, but can only be used in green couch and some zoysias.

          They are rather expensive mind, and are not really available to the public.

              @Qbagger: You will struggle to get rid of wintergrass out of Kikuyu short of picking it out. Products like Poachek have since become inferior as the plant has developed resistance. You could try and look at some pre-emergents, but the cost will probably shock you.

        ITS BECAUSE WE HAD NO IDEA OKAY!

        But seriously, I didn't buy the premixed stuff but it took me a while to figure out I didn't need to buy roundup and anything with glypho concentrate was fine and much cheaper

        gtech on 11/09/2019 - 00:48

        maxwellish if you increase the concentration will it have a quicker and longer-lasting effect??

        • 

          maxwellish on 11/09/2019 - 06:21

          @gtech: No. The plant can only take in so much. Think of it of eating after you're full.

          The marvel of glyphosate is that it moves through the plant slowly, undetected until it's too late. Hence why adding an acid burner to it is silly.

          Stick to label rates and you will be fine. It should take 7 to 10 days to show effects.

            @maxwellish: In my experience using Glyphosate, it's never enough if I dilute the concentrate as per instructions. The weed withers a bit but the leaves are still green. I usually quadruple the dosage and spray it during hot days. This will kill all the weed within 5-7 days. I also use Hortico product from Bunnings. I've tried using white vinegar to kill the weed as well but it's not cost effective. Glyphosate concentrate is far cheaper to use than any other weed killer product.

              @Gorodemon: No disrespect Gorodemon but I think what maxwellish is saying is more correct. I have now heard similar info through multiple credible sources now.
              I was like you and made the stuff in a super concentrate, and had the same results the weeds always died very quickly but they also tended to reappear.
              (what I have been told is that if you make it too concentrate it kills the main plant but it moves too slowly, so by the time it gets to the roots they have had the opportunity to spread).

              @Gorodemon: Vinegar will not do anything to kill weeds, and I really wish this old wives tale was not spread. Instead, use a 'sticker' like a bit of canola oil to help bond the glypho application to the leaf - this will ensure that the active ingredient will be absorbed properly. For glypho with 360g/L usually 10mL per 1L is enough. (100mL per 10L)

              The reason glypo is cheaper is due to the fact it is non selective, and the the patent ran out years ago, meaning a flood of generic products which drive the price down. Selective prodcuts that allow you to spray weeds out of certain types of turf are usually more expensive as the chemisty is more complex.

              Nobody seems to care about these as they are distracted by the Monsanto fiasco.

            @maxwellish: Your feedback on this is great maxwellish

            As others have said, I don't really understand what I am using and I trust the marketing hype on the box.

            I am smart enough to compare like products, and as I say the Roundup Plus or whatever is pretty much exactly the same mix and costs 350% more….

            I like the pre-mixed because it isnt messy, but after I run out of my stock of it, I will switch to your Bunnings Hortico then dilute method.

              maxwellish on 11/09/2019 - 19:34

              @aussietivoman: No worries mate. As someone already pointed out, you are paying for the active ingredient which in this case is glyphosate. Its the same as how Panadol can charge more for paracetemol then Panadene. Its all marketing.

              Grab yourself a litre of the 360g/L concentrate and a 10 litre spray pack, throw on some washing up gloves and mix up your own at 10ml/1L. Be sure to half fill your spray tank and then top up slowly after adding your glypho. This ensures a good mixture. Pressurise your tank and bleed the line in a garden bed or a mulched area.

              That way you will have the correct dose ready to go and apply liberally to folliage. Re apply after 14 days if necessary.

              Good luck

                @maxwellish: Thanks

                I had a bad infestation of some sort of weed on my grass. I dont know the name exactly, it was something like Riccardio.

                It has very significant root networks and spread quickly. If you killed one patch, 2 more would start.

                Nothing seemed to work until someone suggested sulphate of ammonia.

                It was amazing, the sulphate of amonia killed the top growth within 24 hours and didn't seem to adversely affect anything but the particular weed.

    It is not safer to use. The fumes on these products are terrible.

    Applying an acid to the leaf only burns the leaf and will not kill majority of weeds. It will only have a limited effect on monocot weeds such as turf weeds.

    Use glyphosate properly and you will be fine.

    If you wanna safely kill most things in that area you can use white vinigar and salt or boiling water.
