Is This Erwinia on my Phal leave?

It looks like it certainly could be erwinia. Is it kind of watery, and have a nasty smell? Separate it from your other plants ASAP. Cut that leaf off immediately and cross your fingers and hope for the best. To my knowlege there isn't a chemical you can use on erwinia that is effective. Erwinia moves so fast the plant dies pretty quicly.

Give it a good dose of hydrogen peroxide for several days. I've saved a few paphs that way. I've never had it attack any my my phals but it does sort of look like it could be erwina.

Looks like it could be. If you're going to cut the leaf off and keep the plant, isolate it far, far away from your other plants. You might want to proactively spray your other plants with Phyton 27, which is systemic, unlike Physan 20, and clean all table/shelves surfaces with physan or bleach. That's what I did last summer when several phals got hit with what I believe was Erwinia following a prolonged period of high humidity. I only lost 3 or 4 plants and one Ambo that I was iffy on whether or not it was infected with the same has fully recovered and since rebloomed.

EDIT: Be sure to read the safe handling instructions that come with the Photon 27 and wear rubber gloves. It's fairly safe once diluted to the appropriate strength, but you do not want to get even a tiny drop of undiluted phyton on exposed skin.

Cut that leaf off, and it should be the end of it since it hasn't spread to the crown yet. Thtat's what happened with mine at least.

Howard had a bad case of Erwinia last year. He lost a lot of Phals, but I think Phyton 27 stopped the spread.
