How do I fix split bark on a lemon tree that was caused by allowing root stock to grow?

I plan to remove the root stock branch but would like to know if I can help the damaged part of the tree heal in any way. I have had suggestions to "seal" the bark and wrap it but not sure what to use it how to do this. Any information greatly appreciated.

From the image provided, the damage is quite severe. Applying a sealant on to the area may help to prevent access for pests, however, sealants can trap moisture, prevent the 'healing' process, and become a site for disease and rotting. The cracking may also be a sign of collar rot


We recommend to:

- remove any growth that has come from the rootstock

- mulch the area to prevent soil splashing on to the wound

- make sure the area is well ventilated. Don't plant anything underneath the tree, and prune any growth shading or crowding the trunk.

- Apply Yates Liquid Copper Fungicide to assist with collar rot

- Improve growth, and plant and soil health, apply Yates Dynamic Lifter Soil Improver and Plant Fertiliser
