I saw a simular post. I am looking for any ideas that may be causing this. I have a 12 year old grapefruit tree that looks to be slowly dying. Lots of dead branches, yellowing leaves and browns spots on the under side of many leaves. Hope the pictures shed some light. Thanks Jim
It looks like greasy spot to me, but I am not an expert on disease --here is a website that may help: http://edis.ifas.ufl.edu/CH159
