Thought this may be of interest to some.Slasher Weedkiller arrives!!!

We are extremely pleased to announce the release of our organic herbicide, Slasher Weedkiller, after nearly 10 years of research and development.  Yes 10 years! Crazy hey?

Slasher Weedkiller is very versatile and will control a broad range of weeds as well as moss, algae and lichen.  You can spray it anywhere around the house and garden for effective organic control. It works on contact and rapidly burns and desiccates plants so you’ll see results within a few hours.

Slasher Weedkiller is made from plant oils which have been turned into a substance called nonanoic acid.  Nonanoic acid is also known as pelargonic acid and occurs naturally in plants (including pelgaroniums which explains the alternative name).

While Slasher Weedkiller is a powerful herbicide it is still incredibly safe for the environment – it rapidly breakdowns in soils and is completely gone within a few days. Slasher Weedkiller contains no glyphosate and is Registered Organic and approved for use in organic gardens and farms.

Slasher Weedkiller is making its way into stores which always takes time but you can speed things up by asking for it in your local store. We also have it available now from our online shop.   If you’re after large quantities these are available from our commercial division.

From Green Harvest, Slasher is $40 for 1 litre and $100 for 5 litres.

First, I am trying Vinegar. Just the ordinary el cheepo stuff from the supermarket. Nothing added, just use neat Vinegar straight from the bottle.

Early indications are that Vinegar is more effective on grasses than broad-leaved plants. Also that a follow-up spray a week later is necessary and that using plenty of it is more effective than a light spray. Vinegar is not systemic but a contact spray only.

Depends on individual circumstances as do most things. I have several species of grasses and sedges that I don't want on my grassed areas (I hesitate to call the green area a 'lawn'). I also want to replant the bald patches with a mix of Clovers and Couch grass. I'm planning on killing metre-square patches then rehabilitating the soil and re-planting. Then moving on to another patch and so on. A long process but could be worthwhile in the end.

What effect the acid from the Vinegar will have on the soil is anyone's guess at present. One thing for sure: Vinegar is really cheap.

You can add Borax -- very benign. Also cheap.

And toxic. In larger quantities than you might use on your winter Paw Paw trees, Borax is toxic; the reason it is supposed to be stored in shops above kid height,

Elaine, Everything is Toxic!  That is if you consume a high enough dose.  

And that was the point of borax -> we want it to be "toxic" to the insects.  Pretty sure drinking slasher would also be "toxic".   I think we need to be careful about scaring people away from relatively benign alternatives. 

Yes ... but ... spraying it on the ground or the weeds as a herbicide means that it affects the soil and its creatures. I have left Borax behind furniture to kill cockroaches but I wouldn't use it in large doses on the ground. And I use it now and then to add the specific mineral to the soil but in tiny doses.

I'm almost a bit scared to put in a comment, but I have used Boron in the smallest doses on my garden, we are talking a pinch in a watering can.  If you agree with Jerry C W, then he has a write up HERE.   He suggests a dose every 3 years for deficiency.   

People have different views of what is toxic, water, air, soil,  and it is very difficult to find the happy medium.   

Besides that, I think the reason that Dianne shared her find, is that for her to continue gardening, she requires the help of the least dangerous chemical to control her weed problem.  

I hope I have not offended anyone.

Not in the least, Christa. Boron/Borax is very useful in tiny doses. It acts as a toxin when it is used to excess.

As usual, personal circumstances dictate what substances each one uses. For the time-poor, Vinegar is not a good choice as far as I know at present.

Although I hesitate to say it, Glyphosate is a very fine herbicide. Where it is NOT fine is the damage it does to the soil and the soil's microbes. As a long time user of Glyphosate and and observer of the barren soil it leaves behind ... having now found a cheap and maybe effective solution in Vinegar, I am giving it a go.

Again for the time-poor or energy-poor, using a dearer but effective organic solution is probably a good choice.

We each make our choices for our own benefit and taking in all sides of a discussion is part of that decision.

Good find Dianne. Thank you for sharing.

You go guys, this is exactly what I wanted to achieve, a discussion on the Where's and Why For's of the possible use of Slasher.
