There is no specific horsetail weed killer and many chemical options are just not very effective. In small areas, it may be possible to dig the plant up by the roots. It is imperative that all roots are removed, or the weed will reappear. Another option for control involves smothering the plant with a large sheet of plastic. Leave the plastic on for at least one garden season. The weeds under the plastic should die. The best method to keep this weed from taking over your garden is to practice prevention. Improve areas in your landscape that don’t drain well and keep tilling around horsetail to a minimal, as this will only spread the spores.

Pull up as much as you can then put boiling -bubbling boiling hot water on the root area. No chemicals. You could also add salt to the water but if you do nothing will grow in that spot not even grass.
