Glyphosate
« on: May 22, 2015, 09:14:56 pm »
The guy using glyphosate on his field nex tto us was king enough to give us a tin of it. He says it's 4-5 times stronger than we could buy in B&Q.

Here's my newbie questions:

Is it 4-5 times stronger in that it kills 4-5 times as quickly, or in that you need 1/4 or 1/5 as much?

He said "an eggcup" for my wife's 5 litre sprayer. Is there an exact measurement we should be looking at?

Last q (for the moment)  :D "Normal" roundup has to be  mixed about 5 times stronger if you use a watering can instead of a sprayer. Would that still apply to this stuff?

Thanks.

The longwinded dilution instructions with a bottle of the concentrate refer to application rates per acre or hectare and different rates for different purposes.. as opposed to a set dilution for all things. Also when sprayng or pouring on it does depends how long you spray/water each plant.. misted or soused.
You can probably find a full fact sheet via google but the following quote gives you a general guide to work from.

At the 5l per ha dose rate: knapsack dilution rate is 25ml per 1l of water, 5l pack treats 10,000 m2 or 2.5 acres

I used to put a coke can sized amount in a 20 litre sprayer and it killed everything pretty dead pretty quick around the yard

Making your mixture too strong is one of the big causes of chemical pollution from gardeners, compared with large agricultural users, who get it right.  It seems that gardeners take the 'just tip in a bit more and it'll do the job better' approach - this wastes your concentrate as well as the considerable added pollution factor. 

So if you must use the stuff then get the dilution rate accurate.  It's worth going back to source ie the manufacturer, for the correct dilution rate - and be prepared to do the maths. 

Have a look at new research which shows that, in spite of the claims, glyphosate can cause considerable harm.

We are so evil it hurts - I consider my wrist truly slapped  :raining:. There is a move towards weed wiping (glyphos) vs. spraying with selective killers as glyphos. hangs around for a much shorter time/does less environmental damage apparently compared to grass sparing killers

Yeah, those pesky gardeners eh?  ;D

There is a move to ban the use of glyphosate in Columbia ( aerial spraying of illegal drug plantations) as it is felt to be carcinogenic in large quantities. How long before the EU ban its use altogether ??

Possibly just after antibiotics are curtailed in veterinary practice and banned on farms!

what isn't carcinogenic in large quantities?   

As for banning ... so are we just going to completely lie down and allow foreign countries to supply all our food (cos they can do it cheaper as they use chemicals with less prescription, apply fertilisers at rates which poison water courses  and keep animals less welfare friendly) ... or do we fight back with a bit of common sense???
The use of pesticides such as Glyphosate in correct concentration ( preferably weed wiped ) is a common sense way of dealing with perennial weeds.

I agree, we need to use judiciously, it was just when I saw the article about spraying from the air in huge quantities being potentially carcinogenic, I thought someone, somewhere, would see this as a reason to ban for everyone, instead of suggesting there could be other ways to deal with Columbian drug cartels! We need to stand up for sensible use of all chemicals and not rely on cheap food from overseas where we as purchasers have no say in what goes into its production.

Too late! You need to complete an expensive course to be able to buy glyphos. increasing our costs of production.

I agree, but the poster I replied to was implying that adding a good splosh of glyphosate, unmeasured and probably far more concentrated than recommended, was fine.  I don't think it is.

Also, there are other methods for controlling weeds than herbicides, mainly those used by organic growers.  The rapidly growing popularity of organically produced food tells us that many people within our population ARE concerned with the future of our small blue planet.  The issues of overuse of pesticides, herbicides, GM and so on are worthy of very serious discussion and research, not something to be derided.

I don't want to get into an argument here, because I'm only too aware that there are those who don't acknowledge the problem and probably never will, and those who do, but I find it sad that people with their own land to cultivate and grow on are amongst those who don't seem to give credence to the seriousness and urgency of the situation.

So all I want to say is, please take care when using strong and dangerous chemicals, that you use them correctly and as recommended by the manufacturer.  The original poster was asking for help in understanding how to use the product he has, and was looking for informative responses.

Just about everyone in Britain, except perhaps those with a gluten intolerance, has traces of glyphosate in their bodies.  This is because it is widely used in every level and scale of agriculture and horticulture, and in particular it's sprayed on cereal crops to dry them off and prepare them for harvesting.  So if you eat bread which contains British flour, you will have your own personal baggage of glyphosate.  Sounds a bit like DDT in the bad old days.  Nothing we can do it about it now, except not add to it.

Hi Walshie
What were you thinking of using it for?
 
for instance I have spot treated clumps of rushes. Various weeds, just a quick spray into centre. some weeds I'm thinking of trying a wool or cotton glove over a rubber glove, you dip the gloved hand in the herbicide and wipe your hand over the weed, (obviously taking care to keep your skin protected) or you can get roller type implements for same idea,
 
Is it 4-5 times stronger in that it kills 4-5 times as quickly, or in that you need 1/4 or 1/5 as much?
You would only need 1/4 or 1/5 as much.

He said "an eggcup" for my wife's 5 litre sprayer. Is there an exact measurement we should be looking at?
somewhere on-line there is the info you need, I've found it previously when the label got damaged on mine.
 
Last q (for the moment)  :D "Normal" roundup has to be  mixed about 5 times stronger if you use a watering can instead of a sprayer. Would that still apply to this stuff?
'Yes?', (but isn't it the other way round?)
 
Remember splashes or spraydrift of this stuff can kill any plant it gets onto. be carefull
And he shouldn't really give stuff away with such vague advice  :-\
