    Default Phal fungus? Infection?

    Hi everyone,

    Does anyone have any idea what's up with my Phal? This seems like some kind of infection, but I have no idea how to take care of it and it seems to have spread to another Phal as well...I'm scared!!! Any clues on how to take care of this?

    how is the underside of the leaf? i want to guess fungus, but there is something called 'ringspot virus' but i don't think this is it... did this happen suddenly? fungus and bacteria are usually faster spreading. i would remove the leaf and burnt he scissors. and spray with physan or some fungus stuff, maybe systemics.

    Appears to be a fungal infection. concur with coeruleo. cut the infected leaf with a sterile knife and apply a fungicide and observe closely. additional air movement would certainly help.

    To add to the advice you've been given, if you can separate this one and the one it seems to have spread to from the rest of your orchids, that'd be a good idea. Be careful not to over water also.

    I think it may have gotten whatever it is from a Zygo, which had all the leaves fall off from a similar looking threat. I figured nothing of the Zygo (still have it, as it's putting out new green growths and roots) since I know zygos are deciduous and look ugly after a while, though it did happen very rapidly. I can't cut the leaf off the phal because it's down in the bottom...*rubs temples*

    When I see something like that, yellow with spots or rings, I cut it off quickly, before it spreads to the other leaves. It can turn from green to yellow so fast. Never had luck trying to save with fungicides, but cutting off can save the plant. I apply Captan or Thiram powder (staight, undiluted) on the cut with a cotton bud/swab. There was a time where I was too late and had no choice but to cut off all the leaves, but the plant survived due to its strong roots (which yours seem to have).

    What do you mean by "I can't cut the leaf off the phal because it's down in the bottom" ?

    Do you mean its the top leaf? That's what it looks like in the picture. I'd cut it no matter where it is, its going to die off, perhaps you can keep it from spreading. Don't cut the stem of the plant though, just the leaf at the base where it grows out from the plant.
