Regardless of the top-growth control method, allow leafy spurge to regrow in mid-August so a good stand is present to receive fall-applied herbicides. Apply Tordon at 1 quart/A, Tordon + 2,4-D at 0.5 to 0.75 + 1 quart/A, Paramount at 16 oz/A, or Plateau at 10 to 12 fl oz/A in fall. Plateau and Paramount must be combined with a methylated seed oil at 1.5 to 2 pt/A or control will be inadequate. Plateau applied in fall often injures cool season grasses but they typically recover by the following growing season. The later in the fall one uses Plateau, the greater the injury to cool season grasses. Conversely, Paramount is one of the most selective herbicides evaluated in CSU field research on native forbs and grasses, but has a relatively narrow spectrum of activity on different weed species. Fertilization, if necessary and as determined by soil sampling, can help grasses compete with stressed leafy spurge.
