Sedgehammer Herbicide will control young horsetail under 6 inches or suppress horsetail over 6 inches. Please see pages 2-3 product label for complete instructions. We do not have any products that are labeled for arum italicum because it is a newer invasive species. You can use a non-selective herbicide such as RoundUp QuikPro for this plant.
