Three to four additional applications at 4 week intervals will be required to give adequate suppression of bermudagrass and allow fescue or other desired turfgrass species to dominate. To improve suppression and control of bermudagrass, 3/4 fluid ounces per 1000 square feet of Hi-Yield Triclopyr Ester may be tank mixed with a postemergence grass herbicide registered for this use pattern. Three to four additional applications of this tank mix at 4 week intervals should be made to achieve control.

Instructions:
When plants reach the first flower stage, apply 3/4 fluid ounces of Hi-Yield Triclopyr Ester per 1000 square feet. For best results, apply using ground equipment in a total spray volume of 40 gallons per acre. To provide more complete wetting and coverage of the foliage, an agricultural surfactant may be added at the manufacturer’s recommended rate. To control sparse plant stands, use spot treatments. For spot treatment use a 1 to 1.5% solution of Hi-Yield Triclopyr Ester in water (1 1/4 to 2 fluid ounces of Hi-Yield Triclopyr Ester in 1 gallon total spray mixture) and spray the entire plant to completely wet the foliage. In Florida, control of tropical soda apple may be improved by using the following management practices: 
  • Mow plants to a height of 3 inches every 50 to 60 days or whenever they reach flowering. Continue mowing on this schedule through April. 
  • In late May to June (50 to 60 days after the April mowing), apply a broadcast treatment of Hi-Yield Triclopyr Ester. 
  • To control any remaining plants or to thin stands of plants that germinate following a broadcast treatment, use spot treatments.
