Killzall Weed and Grass killer is labeled for ragwort and should do a great job helping to eliminate this weed. Keep pets and children away from the area while you are doing the treatment and they can return after the application has had a chance to dry. Do not treat any areas where the horse is known to graze or in areas that you will harvest the plants for feed. You should note that Killzall is a non selective herbicide which means that it can kill just about any plant that is sprayed. Please read the Killzall product label for complete usage instructions.
