I hauled my boat out in Cape Town just before Xmas and gave her a lick of anti-fouling with a difference. I added a bottle of a common weed-killer called Roundup to the anti-foul just before I splashed it onto Stingo. Two and a half months down the track, there is absolutely no growth to report. The person that gave me the tip has had his boat in the water for three years now and has only hauled her out to change his anodes.

Like anti-fouling, Roundup is an oil based product, so mixes in well.

EDIT: BTW, the mix was 10% Roundup.
 
or walking in your garden where you may have sprayed it
 
Is that hard or erodible.
As we were advised to use 2 coats of hard and then as much soft anti-foul as we liked.
Must say I like the idea though of weed killer.

I'm no ecofreek but that idea strikes me as both stupid and irresponsible. unknown risk all for the sake of a few quid on tested a/f
 
Roundup is perfectly safe for human contact even if drunk neat (some question over human embryonic, placental, and umbilical cells in vitro) but it does have harmful effects on amphibious and marine life. - It is also water based, not oil based.
Probably still not a good idea to use it this way, but it is perfectly safe to use in the garden and with (non aquatic) pets. http://en.wikipedia.org/wiki/Roundup
 
There were stories of people successfully adding horse-grade tetracyclin some years ago(pennicillin). Popping along to my local garden centre ( which is a registered charity to boot) I can still only see green plastic bottles of Roundup.

Clearly for it to be really effective it has to be available in minute black bottles at swindlery pricing and labelled 'Keel Up', ' Keel Haul' or 'Seen You Coming' ?

If Roundup works then you have effectively massively added to the cold beers n titties fund.

Btw is it true that it can be used in certain parts as a blonde hair dye as well to ward off, well, whatever?

I am surprised that it didnt dissolve away quite quickly and the results being due to the original a/f ---- but that is a matter of conjecture. However, consider this:

[ QUOTE ]
Glyphosate is of concern for environmental reasons, in particular its effects on the aquatic environment. It is moderately toxic to fish. The surfactant used in Roundup(tm) is considerably more toxic. Some of the effects of glyphosate on fish include erratic swimming, laboured breathing, odd behaviour, and altered migration and reproduction. Algae and non-target aquatic plants can be affected.

excellent. Jeez, what a bunch of treehuggers have responded. Heyho. Actually i thin the fact that u have been in the middle of an ocean for yonks may have summink to do with it, whatever.
 
If you are going to use a web site called “Guarding-our-earth.com” I would strongly suggest that you also find other sites to balance their view.

A Google search “glyphosate msds” threw up the following at the top of page 1,
http://msds.chem.ox.ac.uk/PH/N-(phosphonomethyl)glycine.html
note it’s oc.ac.uk, would that be Oxford University?

In the toxicity data, ORL-MAN LDLO 2143 mg kg-1 means a 90 Kg man has to eat 192 grams, and that’s the lowest lethal dose reported.

It’s more common to quote LD50 in Rats that’s ORL-RAT LD50 4873 mg kg-1 so to kill half of a population of 90Kg blokes (if they were rats) they would have to eat 483g, that would be almost 900 paracetamol, not easy to do by accident.

The risk and safety phrases don’t set any alarm bells ringing for me, they all appear on antifouling anyway, or should.
R41 Risk of serious damage to the eyes.
R51 Toxic to aquatic organisms
R53 May cause long-term adverse effects in the aquatic environment

S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
S29 Do not empty into drains.
S61 Avoid release to the environment. Refer to special instructions / safety data sheets.
Cheers Bob.
