Marshmello - I saw your cry for help regarding eradicating horse tail in Gardners World magazine and was prompted tp reply.
In my garden I have a huge rockery and when I bought the house the rockery was full of horsetail. I tried every possible weedkiller from sodiun chlorate throuigh many now banned materials for removing tree stumps through glyphosate at various concentrations.
On occasions I thought I had been successful ... but next Spring, up popped the horsetail, unvanquished ------ and then, as if by magic I stumbled on a treatment that worked 100% first time and the horsetail totally disappeared
--- and the material Ammonium Sulphamate , which used to be sold as Root Out.
I caqn't see it on the shelves at the garden centres, so I guess it's been banned - but I'm sure it's aqvailable if you try hard enough
