You could apply Sedgehammer as long as the pasture is not used for grazing. Each 1.33 fl oz bottle will treat an acre.
You will use 1 scoop/spoon of SedgeHammer in up to 2 gallons of water per 1000 sq. ft. Water is only the carrier, so you will use whatever amount necessary to adequately disperse the product over that 1000 sq. ft. area.
Sedge Hammer in the 1.33 oz. bottle will make about 40 gallons worth of concentrate.
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.
Tenacity is not a pre emergent for nutsedge, it is a post emergent for nutsedge. You would use either the Sedgehammer or the Tenacity to kill existing sedges in your yard, but you would not mix the two. In general, there are not pre emergents for nutsedge due to its root system and how it grows. You can only treat it with a post emergent product as it comes up. One product that makes the claim it can prevent yellow nutsedge only is Pennant Magnum, however many do not purchase it due to its size and price often being far too much for most homeowners needs.
The 1.33 oz bottle of SedgeHammer Herbicide should be applied with a surfactant and will cover up to an acre of treated area.
