I had some Horsetail around a pond i had 8 or 9 years ago
when i upgraded my pond i dug and pulled every root runner, any piece of it i could find;
its been gone, i noticed in my neighbors unkept yard over the years some of it was growing .
a few weeks ago i went behind my pond to check on things it was all over the place growing every where, i was just back their two weeks ago
I sprayed it with Crossbow hope its down for the count ...it looks like it is
