So i stumped it and then left it alone....and it grew back.
10.8.22 has some suggestions to try for those wanting to try to help protect a avocado tree... Very interesting ideas. I might quote a few, but here is the link:

The most important step to take is to get the mycorrhizae back into the soil to help support the tree. All trees are considered mycorrhizal dependent, so don’t grow your trees without them. Email me at sasc@ufl.edu if you don’t know how to get the biology established around the root systems of your trees, lawn, ornamental plants and everything else you want to grow in your yard.
Fertilizing correctly is also important, and that begins with a soil test. If you are interested in that I can also email you a copy of our soil testing form. It takes time for the soil food web to get established, so identifying low levels of any nutrients will be easy to correct.
To produce nutritious avocados, it is also beneficial to re-mineralize the soil with trace elements from a volcanic source, at least while the soil food web is getting established.
Another beneficial practice for the tree would be to spray the foliage with a liquid seaweed spray. This is a simple way to provide trace elements and growth hormones directly to the foliage of the tree, for translocation throughout the entire canopy. Spraying weekly will provide the most benefit.
One last thing you can do to help boost your tree’s defenses against the fungus would be to add aspirin to the liquid seaweed solution and spray them on the foliage together. Research at the University of Rhode Island found that spraying a plant’s foliage with salicylic acid from aspirin results in a Systemic Acquired Resistance in the plant, which can help the plant protect itself from insects and diseases.
In the research, ¾ of an aspirin was dissolved in water and sprayed on the foliage of plants. It may be easier to dissolve 3 chewable baby aspirin, in a small amount of hot water, add that to enough cold water to make a gallon, and add the liquid seaweed to spray them together."
A few new ideas like the Aspirin addition, at least for me.
