If I am careful to spray Crossbow only on horsetail will it kill my plants?

I have a major horsetail problem. It is mixed in with my plants. If i am careful to spray Crossbow only on the Horsetail will it kill my plants?

Answer:

Helena Crossbow Herbicide will damage ornamental plants such as flowers, shrubs, and trees, so you should not apply it within the drip line of those plants. Crossbow also has soil residual, so you would not want to apply this where you intend to transplant new ornamentals, either. Keep in mind that Crossbow is labeled for control of horseweed (marestail, an annual weed), but not horsetail (a perennial weed).
 
You could use Sedgehammer Herbicide for control of young horsetail in areas with turfgrass or around woody ornamentals.
