Timing / treatment |
| Garlon 4 |
5% in water |
Apply as a directed spray. Keep the spray off the pine needles. A backpack sprayer with a wand can be used to spray the vines to about 6 feet, Use an adjustable cone nozzle adjusted to produce nearly a straight stream to target the vines. Sometimes only the lower vine can be sprayed when the vines are climbing in the canopy. Backpack sprayers with a diaphragm pump are best. (from Dr. Patrick Minogue, UF-IFAS SFRC) |
