Hello Dr.Sunny.

As far as I can make out the weed is Euphorbia helioscopia commonly known as sun spurge or madwoman's milk.
The common name refers to the milky white sap the stems exude when cut or pulled, a highly poisonous sap hence the name madwoman's milk.
This weed is classified as a class "A" noxious weed and is toxic when eaten by cattle and horses

It dies each winter only to return the following spring by its previous years shed seed.
It usually grows to a height of about 40 centimetres (16 inches) and flowers between April and July.
It can be removed by hoeing or hand pulling, with gloves recommended due to the irritating effects of the sap.
Avoid rubbing your eyes or face after handling the weed and always wash with warm water afterwards.
It can also be controlled chemical means, do this by spraying the weed before flowering with the lawn weedkiller "Verdone 2".

10 would be something that was carnivourous and smelt of rotting flesh and caused subsidence of any buildings nearby and caused temporary blindness and incontinence just by being seen. Horsetail is a 9.5.
Spurge is a 1 alright.

Laughing Horsetail was used in former times for cleaning pots and pans because of the high silica content . I had to get rid of it on an all weather sand based pitch where there was no problem spraying . I tried Roundup , SBK , and various other products and thought I was successful over a period of two years spraying . I got a call this year to spray again , when I went out there were beautiful healthy plants growing there , definitely 9.5

I have heard that the horsetail is partly resistant to roundup because it just washes off. Three possible solutions (never tried any so presumably they do not work Smile I have heard are: 1) mix up wallpaper paste using glyphosphate solution instead of water and paste on; 2) bruise each plant before applying; 3) you can get roundup specially formulated to stick to horsetail; 4) consider it as an ongoing business opportunity.

I would be interested to try that wallpaper paste solution, Des.

It seems that horse tail or mares tail as some people call it has a waxy outer coating which the glyphosate cannot penetrate before being washed off.
I have found in the past that mixing a main part glyphosate with a lesser part SBK brushwood killer has been quite effective (by that I mean it still took two years applications to almost totally remove the weed).
The SBK's paraffin type content seems to break the horse tails outer coating allowing the glyphosate to enter.

have a look at http://groups.google.com/group/uk.rec.gardening
and search using the Search This Group button using
wallpaper paste and/or horsetail and you get dozens and dozens of hits.
Here is what one person said:

"A very invasive and prehistoric plant. Difficult to eradicate completely.
Heres the tips. In september, you dress the plants with a systemic
weedkiler - with glyphosate. I mix some wallpaper paste in with the
solution and paint it in the plants. You need to do this regularly, and you
will eventually get on top of the problem. Weedkilling in the early summer
will have no long term benefit I'm afraid - wait till the autumn.
Here speaks a man who once had a major horsetail problem - and conquered
it!!

David"
