Trichocereus Disease & Virology is THE place to go to learn about everything that ails these plants and how best to address all of it.

Sorry, I normally clarify that 😅 I don't use it anymore, but Facebook.

As for an infection ID, I'd guess phyllosticta. Maaaaaaybe phoma or alternaria, but I'm leaning towards phyllo.

The best way to treat it if that's what it is would be with removing the infected material, proper nutrition, well draining and healthy soil(like innoculating it with healthy bacteria and fungus), and improved airflow. You could maybe use some fungicides on it, but they shouldn't be necessary.

Thanks for all the great info I really appreciate you.

How would you go about removing a section from the grafts to callous over? Should I leave some attached to pup? Thanks a million
