Is this horsetail?

Hi, this has suddenly sprouted up. I think it's horsetail, but I'm not sure. I hope it's not! Any ideas?

Weed membrane is not a good idea the marestail break through eventually and make removal even more difficult.
Buy some ammonium sulphamate ( 1kg ) and some wallpaper paste powder, mix together with some water and washing liquid to form a paste. Wear a rubber glove and spread the paste on each stem, if possible I would then cover with a clear plastic bag to stop the paste being washed away. Carry on with this as and when each stem appears, it’s a long process but it will work.
East facing, top of a hill clay-loam, cultivated for centuries (7 years by me). Birmingham
Does it? How long will it take? Will you live long enough to see the weakening?
It is right up there with “cover it with membrane, the lack of light will weaken it”
If any of this was true then why do we have so many threads asking for advice on MT growing through membrane? And statements from people who have been pulling it for years, one poster said they had been pulling for 35 years!
Weed killing chemicals are the only solution.
I used chemicals last year. It looked a right mess as it died.
This year I've pulled it up as it's appeared. My garden looks 100x nicer.
It will definitely come back, but let's face it even with the aggressive chemical approach it'd probably come back anyway!
