Just an idle question, but is glyphosate
the same as Roundup?

I notice people on this group have suddenly started
talking about glyphosate;
I don't recall seeing it mentioned until recently.

Roundup is a commercial name for glyphosate.

Glyphosate is N-(phosphonomethyl)glycine. This is a compound which
interferes with the shikimic acid pathway in plant metabolism inhibiting
the synthesis of some amino acids, and thus protein synthesis.

Roundup is a formulation including glyphosate as its active ingredient,
but also including surfactants to increase plant update of the
glyphosate. Tumbleweed is another formulation. (I'd tell you to read the
label to find out what the active ingredient is in a herbicide, but on
several occasions I've found them opaque.)

I believe that on occasion that active ingredient in a weedkiller has
been changed, but the brand name retained. So perhaps it's better to
avoid the use of brand names.

... but the active ingredient glyphosate can be bought in other proprietary products ie Round-up is glyphosate but glyphosate is not necessarily Round-up

Another important difference is the price. Ghyphosate is a generic name
of the most common weed killer ingredient and is always far cheaper than
paying for the same product under a brand name. Roundup can cost between
ten and a hundred times as much as generic glyphosate to treat the same
area!!!

Sound advice. Note also SRH's info. In case you're worried about these
things (as I am), bear in mind that glyphosate, while it may be
unnecessary most of the time, seems to be environmentally pretty safe,
since it's neutralized on contact with clay particles in the soil.

Glyphosate is immobilised on contact with clay particles in the soil
(and therefore isn't subsequently absorbed by plant roots). It is
subsequently degraded by bacteria. A typical soil residence half-life is
a month, but it varies - it could be a few days, or several months.

It's said that the surfactants included in the formulations have worse
environmental effects than the glyphosate.

It comes up from time to time. Usually only when the weeds are growing
strongly!

Don't know in England. In France the larger garden centres and
agricultural stores stock it. Usually in 5 litre or 2.5 litre containers
of concentrate. The concentrated glyphosate goes a very very long way.

As I've said before, do-it-yourself shops in France.

You cannot actually buy Glyphosate as such.

A concentrated formulation of which it is the main active ingredient, is
available in agricultural type places in five litre containers.
I paid about £30.00 for some just recently . It is used at a concentration
rate of about 2 percent, so it works out a factor of ten or more
cheaper than round up types of stuff.

You will have to ask for it at the counter as it is normally kept under lock
and key in secure storage, and is not on display.

Different to France then, it is on the garden centre / DIY shed shelves
along with everything else. But then in France you can also buy off the
shelf things like gin traps (illegal in the UK) and concentrated acids
and other hazardous chemicals.

Anyone know what the big gin traps in France are for? They almost look
big enough to catch humans! Much bigger than the old rat ones in the UK.
Foxes or badgers perhaps?

Glyphosate, in liquid concentrate form, is available at my local
Wyevale Garden Centre and so I suppose it's also available in other
stores in the Garden Centre Group. A neighbour bought some in powder
form at a local B&Q.



In small quantities at high prices - no doubt !

It would be surprising if you know anything about the sizes or
prices of the product you claimed is unavailable.

Indeed - I have not gone into much research on the prices and sizes of
products containing glyphosate.
