I've heard that vinegar can kill this stubborn weed.
Pull,dry,grind it up and sell it to a Health Food store. Horsetail is a Herb. You can chew it also for a Nicotine fix.
Use "Horticultural Vinegar" and rock salt. Grind/pulverize the rock salt and let dissolve in the vinegar. Inject the horsetail with a meat injector. It should dry up in a few days
I second the rocksalt advice... it works on a array of weeds around the home. And grass too... be careful
