Decided to try the organic approach. First up the cost was at least twice as much. The application use was 7 times more per litre. The result was quite quick on young weeds, but other more established weeds not so good, a few days later you could not see any result or where you had sprayed. I think for the sake of going organic you need to be MUCH more cost effective. Much better results from Roundup. ( Slasher 20 Ltrs $302.00)

I purchased this from Woolies to kill broadleaf. I normally purchase Bioweed online but I was at the supermarket
I purchased this from Woolies to kill broadleaf. After following the instructions, I found it only burnt the top off the weed and didn't stop it from growing back. Disappointed with the result.
For small applications only, if you can’t physically remove.
I wanted to de-weed en-masse using this product so badly. So disappointed even though there’s no silver bullet (there rarely is). I’ve used to spec and then some. Tried over two seasons with very average results. Won’t be purchasing much unless on spesh or desperate. Have made my own, which works better than Slasher, as I won’t use glyso.
Still balancing the bleach, vinegar, salt and detergent & boiling water. Esp being thoughtful around water courses.
Won’t be using this until mid summer when weeds are in full sun.
I’m on 6 acres.
orchard use, happy with product
I use this product in my 6.5 acre cherry orchard with motorbike pack sprayer. It will knock down tall plants having to repeat again later to give better effect. At times it may take a third spray for kill. As my trees bush up they suppress weed growth and some cover can keep your plants cool and the worms happy. Sure you do not kill all the time but you do not lock up trace minerals in the soil like round up does or affect your own cell health. It is a lot cheaper from ag supply shop and is the most cost effective ($290/20L)for and safe herbicide so far.

Shake the bottle spray it on and it turns the weeds to jelly in a few hours, I don't even remove them as on woodchip you can't see them within about 8 hours. Brilliant product. Did I mention shake the bottle before, during and after.
No garden product is worth risking the bees or our pets for and this one doesn't.

Hi, further to my previous review, today 9/1/2020 I phoned the company responsible for this herbicide, they promised they would have a specialist contact me regarding its inability to kill perennial weeds. I won’t hold my breath waiting for contact from them.
12/1/2020 To the manufactures credit they have contacted me and have asked me to send in a sample of the herbicide so they can have it tested.

A great alternative to protect our bees
This product works in a day or two and I'm very happy with the results. I've tried and tested other organic products including homemade, but this gives the best results.
However, if you're looking for a Kill--All, glyphosate, carcinogenic product and want a pristine garden look, this may not be the product for you. Slasher has been made for the conscious environmental people in mind, who don't want to spray and kill everything in their garden which isn't an official flower. Wildflowers can be beautiful too and the bees need them. Highly recommended!
Hit and miss
If you're looking a non toxic liquid to spray around this may be it.
However if you're looking for a silver bullet,this is a long way off
Well if like me you want to;
>use less chemicals, minimise the frequency of additional runs to kill weeds,
>kill weeds before pre seed set to lower eliminate future weed issues,
>at least come close to some of the main (positive) attributes of glypho, this is not it.
It seems you need a perfect lining up of ducks which is not likely to happen.You would need the weeds to exist in full sun, have several ...
worthy of zero starts (pardon the pun)
This eco friendly product is also weed friendly. As in the photo on their website, it does indeed seem as if the weeds die in 24 hours. But guess what? Like Lazarus they rise again from the dead. Every time. Total waste of money, and it's expensive too. Back to glyphosate for me. Very disappointed.

Could be cheaper but good
I still find flame weeding is the cheapest and quickest method but it does present problems for about 6 months of the year.
Compared to flaming, slasher wins on convenience (not having to lug around a 9kg propane tank and not having to worry about setting fire to things) and it loses on cost and being a bit pongy.
I would say slasher is just as effective as flaming and takes about the same amount of time - while it is expensive compared to propane, it still only costs a few dollars to weed the whole property so it is still a feasible solution.
Expensive and not really a replacement for glyphosate.
Not only is this more expensive per litre (than generic glyphosate weed killers), you also mix it at 70ml per 1 litre of water.
I bought 1 litre of Slasher from Bunnings for $29.95, a generic glyphosate weed killer (like Hortico Weed Killer 360) costs only $9.90. The Hortico 360 1 litre container can make up to 200l, the Slasher 1 litre only makes 14.3l !!! So it's comparatively extremely expensive.
Slasher does start to give visible results within a couple of hours (weeds visibly wilting), whereas glyphosate is comparatively very slow to g...ive visible results. The Slasher hasn't been as effective with narrow leafed weeds with them not showing much (if any) visible effects after a week. A couple of Bindii weeds also seem to have survived with only some small brown patches on the leaves.
Organic certified products are always the best to use.
20 yrs ago approx, when operating my Landscaping/Garden maintenance business & as part of my ongoing research into organic products, I discovered Slasher. Trial & error got it right. Semi retired now & till using it at the local school where I am gardening. The extra dollars it cost is balanced by it being fast & efficient.
Its time to shift away from Glyphosate (aka Round-Up)
Been testing with this product for about a year now in varying temperatures and conditions. Professional gardener, so I use these product types regularly. It has worked fantastically in warm conditions and used it last week on a cold miserable day for the first time and it still worked great! I used some Round-Up in the same garden on the same day and a week later the weeds are barley yellowing with the standard concentration used, while at standard concentration with the Slasher, all weeds now fully dead.
You must apply a good coverage to ac...hieve maximum results with Slasher while Round-Up acts systemicly and has a small advantage here. That said, Slasher is very fast acting and in my opinion a far superior product. Other complaints have been its a little more expensive, yes, that may be so, but the effectiveness on weeds is better and particularly for the home gardener a large bottle once a year should be plenty. I feel now we need to be more conscience of what we are putting into the soil as a society also. Round-Up is a phosphate containing compound, which for Australian soils in particular should be avoided. So, by using this product, you are only doing your surrounding garden and environment potential damage. On top of that, we are now seeing court cases in the USA against Monsanto (the Round-Up creator). The last case (May, 2019) ordered Monsanto to pay 2 billion US dollars to the plaintiffs who have now likely obtained cancer from extensive use of this product. Anyway, despite all this. Slasher actually works better than Round-Up.

An Effective Organic Herbicide
Slasher is certified as organic and this is it's great advantage. It is expensive and difficult to use but it can be effective. It is essential to read the directions (when all else fails) as the two essential prerequisites for success are that the leaves are dry and receive a full cover. I use Slasher in the wet tropics which is a difficult area to gain control of weeds because of high moisture and plant growth.
Slasher is very effective on broadleaf plants at the 2 or 4 leaf stage and is ok on broadleaf grasses but struggles with established ...
Questions & Answers
We have some hired beehives.
I want to spray the grass next to them to stop it growing and covering up the Beehive entries.
Will Slasher on the grass harm the Bees ?
I’m guessing Europeans. Personally I’d weed mat etc underneath them so you don’t have the same issue over & again. I’d hand spray In controlled stints with small hand spray on a still sunny warm morning (or even onto a gloved hand and wipe/paint it) on said herbage near one and see how you go. Make sure it’s sunny & dry on the weeds. Works quicker. They’re off ground so bees shouldn’t come into contact.
