Tape2Grape – Biobased, biodegradable grafting tape for fruit growing and agriculture

Tape2Grape is a 100 percent biobased multifunctional grafting tape for fruit and ornamental trees, which can be equipped with individual biological ingredients. Tape2Grape is biodegradable and therefore makes an important contribution to holistic, ecological agriculture.

Challenges

In commercial fruit growing and agriculture, the grafting of woody plants plays an important role. In the refinement process, grafting tapes are often used to close the "open wound" on the tree and to encourage it to grow together. As consumables, the grafting tapes available are mainly made from petrochemical raw materials, end up in the ground and are not biodegradable or only very slowly. Tape2Grape represents an environmentally friendly alternative here. On the one hand, it is 100 percent biobased and, on the other hand, it is also biodegradable and therefore does not pollute the environment.

Objectives and project plan

The aim of Tape2Grape is to produce a multifunctional, 100 percent biobased and biodegradable grafting tape. With the targeted use of antibacterial, antiviral and antifungal components, the tree should be actively supported in the healing process by preventing such an infestation on the open tree wound. It is also possible that the grafting tape can be equipped with an individual fertilizer that is adapted to the location and the plant.

Impact

Tape2Grape represents an economic and environmental value in the commercial as well in organic fruit growing. The grafting tape is made from biobased polymers and can be equipped with bioactive substances. Due to its biodegradability, the tape can remain in the growing area after the grafting process and rot, as it is not harmful to the environment. The new grafting tape Tape2Grape can also be tailor-made for certain requirements, e.g. equipped with fertilizer components. In this way, further significant advantages, such as soil improvement, can be achieved as a side effect if it rots on site.
