    Default Orchid virus?

    Okay. What the heck is this on this phal leaf? I panicked and I cut it off. Don't want to risk it spreading.

    Looks like what happens when the phal is watered too late in the day to me.

    Yes could be a edema or a mechanical damage. hope you have sealed the cut with the fungicide or cinnamon.

    My first reaction when I saw the leaf was, that's not so bad - shame that the leaf was cut off, but oh well.

    The damage that I see in the first photo, described using deeply scientific terms, is a "boo-boo". By which I mean it appears to be minor, cosmetic damage due to some mechanical cause. Looks like something scraped or cut it. If it was a plant of mine outdoors, I'd blame the pesky squirrels. Or maybe the cat. Or possibly the really clumsy orchid grower that seems to cause most of the mechanical damage to my plants.

    My plants grow outdoors during the summer, so for the older plants, I have very few that don't have at least one boo-boo. As would happen in nature on a wild plant, if I see a boo-boo on one of my plants, I typically just leave it alone and let it heal naturally. I do try to keep the damaged leaf dry for a few days, and keep it under observation to make sure no bacterial or fungal infection sets in. For a healthy plant, there is no harm brushing a little cinnamon powder on the broken tissue, but it is not really necessary; with or without spices, the damage will form a scar, and 99% of the leaf will keep functioning.

    The title of the original post raises the question as to whether this could be the result of a virus. I participate in several orchid forums, and this seems to be a recurring question. I used to ask this question myself; is some problem that I am seeing, in my plant or another, the result of a virus? Lots of growers more experienced than me kept repeating the same advice: you can't identify ANY virus just by looking. The only way to identify a virus is by testing. There are some symptoms that would make me suspicious, though. Rather than repeating the symptoms, I would suggest that you Google the phrase "orchid virus symptoms" and look at some of the papers that show up. Here are some links to good ones, some show pictures, some just talk about preventing virus transmission:

    Remember, matching your plant to one of the pictures is not a virus diagnosis. You can see similar symptoms for other reasons, such as fungal infections or environmental damage.

    I hope this helps put you mind at ease regarding your plant.

    If the pockets yellow then I would assume the plant is storing more water than its using and to lessen watering. Otherwise my first thought as Catt said.... boo boo

    Lol.... so maybe I jumped the gun a bit. Lol. I'm new to phals but I have 10 and 1 mini phal... all saved from various places. I guess the mere thought of me losing all of my rescues made me overreact a tad... Lol
