How do I kill ( Chocolate vine )Akebia Quinata. Double Strength Glyophosphate did not kill It.

Answer: Chocolate vine can take over an area if its left to its own devices. Doubling the strength of Glyophosphate doesn’t necessarily double its effectiveness, as long as some of the glyophosate is absorbed into the plant its systemic action should control the plant.
You should try and increase adsorption into the plant, you can do this by adding a surfactant into your spray mix. You can use a commercial product for this or add some dishwashing liquid into your spray. You should also apply when the plant is actively growing as this increases its efficacy.
As this seems to be a persistent weed you might need to reapply every month, if you continue to see no effect you may just have to pull it out by hand.
