Roundup in antifoul.

[oldsaltoz]

Not sure if you have the liquid weed killer called roundup in Europe, it's common here in Oz.

Just had an e-mail from a friend down south (Queensland) asking if anyone has used it mixed with Anti foul paint? as the practice was growing down there, he claims it keeps the groth down.

I can't imagine what damage this must be causing to the environment, sounds about a good as adding pepper or chilli to the paint.

Good luck all and fair winds.

Isn't that the weedkiller based on "Agent Orange"?

 

[sarabande]

glyphosate.


Probably the most common industrial / agricultural total weedkiller available.


Please don't even consider using it as antifoul !


Check out the glyphosate MSDS



Stingo did it once

Not sure where in Oz your from,
But im from Terrigal on the Central Coast and am now in Europe, Ive mentioned it a few times to people here in Holland and the UK and noone knew of this addition to antifoul,
I know i used to walk around the marina in Nelson bay and you could look at all the boats who had used roundup as the seagrass under the boat was all not there, and there was a direct outline of the boat hull, looking to the sand yet sea grass elsewhere,

Just wondering how much roundup is used near the coast & runs off into coastal waters.
More than the few cups some peeps use in their AF ??

 

[Twister_Ken]

RoundUp instructions are very clear about NOT using it near watercourses.

Roundup is inactivated very rapidly after contact with soil; it works by being rapidly absorbed through green leaves. So in answer to your question I suspect very little.....

From the manufacturers website:-

Aquatic use

Safety to the Environment

Safety to the environment is an important consideration when treating weeds in and around water. Roundup Pro Biactive is particularly suitable for these areas. It gives effective weed control, and is quickly broken down in soil or sediment into harmless natural substances. It is non-residual, and does not harm animals, birds, fish, insects and other wildlife.

Biodegraded
When Roundup Pro Biactive is used correctly, only a small proportion of the spray reaches the water. Any herbicide which enters the water is rapidly broken down by microbes.

This was confirmed by monitoring sites after application. The amount of glyphosate found in slow-flowing water one hour after treatment, and in still water 12 hours after treatment, is barely detectable. At these sites, the variety and number of micro-organisms showed no significant change during the year after treatment.

Evidence suggests that Roundup Pro Biactive has less effect than mechanical weed control on wildlife.

splash it on all over

having been an agricultural hack specialising in arable crops and chemicals I have spent quite a lot of time wading through environmental reports and guessing at the stuff that they leave out of the reports so that I can ask the right questions

"rapidly" - what does that mean? - in a minute, in an hour, in a month

"barely detectable" - wonderfully subjective term - DDT was barely detectable yet had devastataing impacts on the environment to the point where it was persisting through to human breast milk - which cannot be a good thing.

"At these sites, the variety and number of micro-organisms showed no significant change during the year after treatment."

significant is a statistical term it does not mean no impact it means too small to pass the maths test applied to the figures

- but what is the impact five years down the line after repeated contaminations - did they look at repeated contaminations - of the type that being used as an antifoul would imply

when used on a boat hull then this stuff will be floating off into our precious environments right through the year

I am not saying it is not safe to do this..... just that we don't know if it is safe

so chaps......please don't do this until some-one has done the tests

of course, no one will know if you do it, but if it goes wrong and it does damage the environment then we as sailors will all be criticised for it

Can't help feeling that if was that simple and that safe the manufacturers would have been sticking it in their gloop way back.

 

[Ariadne]

I know people who use regually it around Italy where they propblems with mussle growth as well as high rates of other growth.

Buy the cheapest antifoul you can find and work on 1 or 2 capfull per litre seemed to be the norm 3 years ago. Worked for them!!

 

[Seajet]

I'd be pretty sure it's illegal to bung in supposedly powerful stuff like Roundup.

Then again my girlfriend was married to a top bloke in ICI so used to get a lot of stuff at low prices; she swears the modern Roundup is a pale imitation of the real Mcoy.

Dylan, hate to say this in your presence but since taking on a BIG garden my views have changed; used to be a raving Green type, now when looking through garden centres I disregard anything which doesn't have a skull & crossbones & 'Warning; Nuclear/ BioHazard' markings.

We're nowhere near the sea or rivers though and get lots of happy wildlife, promise.

One wonders just what science could dream up for anti fouling if the only design restraint were to try not to kill the hapless boatowner having a wee swim near his boat....
Tin, arsenic, used battery acid, agent orange, all mixed up into a once-in-a-lifetime application...

Have ytou looked at the price of Roundup? It makes antifoul look cheap. In fact I'd be more interested in using antifoul on my weeds that the other way round.

Once met a Swedish gynacologist who was starting his retirement RTW cruise. He had dosed his antifoul with streptomycin which he reckoned worked really well. The cost of a few kilos wasnt an issue - the Swedish NHS paid for it.

TBT works very well, but is now illegal for recreational use - commercial shipping can still use it, though. But TBT might not be entirely harmless to the boat owner! It was in widespread use when I were a lad, though.

 

[Pasarell]

Sorry Antarcticpilot but TBT cannot be used by commercial shipping. There was an extended period when it could be used after being banned on leisure vessels but that finally came to an end several years ago. In practice it was banned in Europe and N America quite a few years earlier. Can't remember the dates exactly now but definitely not allowed. The regulations about what is allowed are basically the same for any kind of vessel from rowing boat to super tanker and including naval vessels.
The restrictions on biocides that are allowed in antifoulings are closely controlled both in type and quantity. All the big marine paint companies have tried out pretty much every biocide available and use what is allowed. Adding other biocides to make a personalised cocktail, whether it involves drugs from a consultant doctor, or garden pesticides is grossly irresponsible.

Thanks for the update - obviously I am a few years out of date.
