I never thought I would write a post like this but now I'm pretty sure my loved Deshojo got Verticillium from an unsealed small pruned branch.
I didn't think it was so easy for this fungus to enter a susceptible species.
All the leaves of this branch, after leafing out fine this spring, suddenly became limp from one day to another.
Below you can see the unsealed cut. I thought the fungus would mainly come from the ground or infected tools.
The buds on the secondary branch on the right never leafed and I thought that was just the tree deciding to channel the energy elsewhere.
The secondary one on the left is the one in question.
In this photo you can see the other side. It doesn't seem that the part below the point of entry is affected but I'm pessimistic about having removed it all.
Here you can see where that branch was attached to the tree. Now I sealed the new cut.
My questions are:

My questions are:
- Do you think the disease already spread below the cut branch even if I can see no sign elsewhere?
- How fast does Verticillium spread in a tree?
- Would you cut the rest of the main branch up to the trunk? (the leaves are healthy there)
- Would you use some antifungal to try to stop it?
- In a few words what would you do?
