Helena Crossbow Herbicide is not labeled for Japanese climbing fern or Old World climbing fern. Unfortunately, there currently are not any selective herbicides labeled to control these invasive vines. Using a non selective such as Roundup QuickPro that contains atleast 41% glyphosate is recommended and repeat application will be needed. Avoid contact with desirable plants by directly spraying or brushing the application onto the vine.
Please review this article from Alabama A&M Extenstion Office for more information.
