12. Management PreventativeCulturalMechanicalBiologicalChemical

13. Preventative 1.Limit planting as an ornamental 2.Remove existing plants, including tuber and rootstocks, before seeds are produced 3.Prevent seed spread and dispersal

14. Cultural 1.Alternative landscape plants to replace coral vine 2.Programs to educate homeowners about the problems associated with coral vine and proper identification 3.Maintain good ground cover and mixture of plant species to reduce establishment

15. Biological 1.There are no known biological control agents available for coral vine management in Florida or the southeastern U.S.

16. Mechanical 1.Hand pull young seedlings, including all roots 2.Continuous cutting to deplete food reserves, will take several cycles 3.Physically remove (dig up) tuber 4.Mowing would be effective but multiple mowings would be necessary – generally not possible

17. Chemical 1.Limited research in this area 2.Over-the-top foliar applications 3.Thoroughly wet leaves with herbicide Triclopyr – 2% solution Triclopyr – 2% solution Glyphosate – 2 to 3% solution Glyphosate – 2 to 3% solution Use surfactant at 0.25% Use surfactant at 0.25%
