Using 2 quarts of 2,4-D per acre of horse hay, the amount of 2,4-D per acre came from MSU field crop educator but he didn't tell me how much water per acre.
Per the product label for Hi-Yield 2, 4-D Selective Weed Killer: In established pastures and rangelands, use 1 gallon of this product in 15 gallons of water per acre per application per site. The preharvest interval (PHI) is 7 days (cut forage for hay).
