We have a bad problem with air potato (Dioscorea bulbifera) and nothing seems to work against it. I know a systemic herbicide is required, but this stuff is tougher than poison ivy to control. Does this product control air potato? If not, can you name a product that does?
Bonide Poion Ivy and Brush Killer is not labeled to control air potato so we can not advise that it would kill it, just the manufacturer has either not tested against this plant or did and did not find it effective. We were able to find a great article on how to treat air potato and believe that the Crossbow Specialty Herbicide might be a better choice. Be sure to include a non-ionic surfactant for best results and that it can take multiple applications.
