Answer: You can apply Tenacity Herbicide multiple times per year as long as you do not exceed the maximum annual rate of 16 oz per Acre per year. To treat yellow nutsedge, you may need to reapply Tenacity after 2 to 3 weeks; be sure to use a non-ionic surfactant for post-emergent applications.
How long does tenacity take to kill?
How quickly does Tenacity work? Once absorbed, Tenacity quickly translocates throughout the plant. Weed growth is suppressed soon after application, as photosynthesis is disrupted. Death of the plant usually occurs within two to three weeks.
Do you need surfactant with tenacity?
You will need Tenacity Herbicide, a pump sprayer, water, and a non-ionic surfactant to help the weed killer stick to the plants. Food coloring or a turf coloring agent is recommended to mark the areas where the weed killer has been sprayed.
What is the mix ratio for tenacity?
For large areas, the typical application rate is between 4-8 fluid ounces per 30 gallons of water per acre. For smaller areas and spot treatments, a half teaspoon of Tenacity in 1 gallon of water will treat 1,000 square feet.
