Beginner Gardening: Loquat Trees with Burnt Looking Leaves, 1 by GeauxTiger

I'm assuming this is some sort of fungus, as both my little loquat tress potted on my patio have come down with this over the past month or so. They are both the "grand-kids" so to speak of loquat tree that was in my front yard growing up...so I'd sure like to save them if at all possible! Anyone know what this is, and if so, what to do to remedy the situation?

Background info:

- Located in South Louisiana...zone 8b
- Both trees were from seedlings from a previous tree that was growing in my yard and are currently potted

Thanks in advance for any help you can provide!
