Help with Avocado Tree!

[dorian]

I noticed yesterday this cut and white stuff growing around it on my avocado tree. I am not sure if some insect or fungus is doing it. I am concerned it will kill my tree if it keeps going.

I tried peroxide and copper spray, the white stuff came back. I am not sure if I should open up the bark and dig in to try and clean it before applying tanglefoot.

If anyone knows what this might be or has any advice I would really appreciate it.

Thank you,
Dorian

Its sap, leave it alone the tree is healing itself.

I am talking about the two gashes. I am afraid some beetle/weevil or something of the sort has gone in there.

You can use a box cutter and slice that off and cover with plastic tape.  Or just leave it alone and not worry about it.  It looks pretty minor but its hard to tell since its just one close up photo.  How does the rest of the tree look?

The white stuff is sap.  Its the trees blood leaking out and forming a scab and healing itself.  Dont keep wiping it or adding chemicals or tanglefoot.  Its a living being it can heal itself.

The rest of the tree looks fine I think, but it was at a major junction so I was afraid I'd lose all the top growth. It was rotting inside, but I didn't see any insects with the naked eye. I cleaned it up best I could and wrapped in parafilm. Hopefully it heals.

What age and variety is that avocado tree. Looks very well nourished.

The root system is almost 5 years old, but I top worked it last year, so the top growth is almost 1 year old.
