The Crossbow Specialty Herbicide - 2,4 D & Triclopyr is not labeled for field horsetail, only maretail (horseweed) and horsenettle, so we can't say whether it would effectively control or not since it hasn't been tested or labeled for that weed. Except for lactating dairy animals, there are no grazing restrictions with Crossbow Specialty Herbicide - 2, 4-D & Triclopyr following application of this product. Please refer to page 7 of the product label for more specific grazing/haying restrictions. Field horsetail is difficult to get rid of once established because it's resistant to most herbicides and its rhizomes spread widely and deep. We would recommend contacting your local Dept of Agriculture for recommendations in your area.
