    Thanks all.
    I'll perform the procedure asap or Saturday if I don't get to it before then.
    Gin, I did order some finer bark on Feb 24 but it has still not arrived. I asked them several times when they send it but I think I'm "barking" up the wrong tree... (I know, very cheesy).

    Make sure you sterilize any instruments you use to cut and please keep it isolated from the rest. I'm sorry to say that it looks just like a virus that my catt had a few months ago and I had to dispose of it before it infected the rest.(I took the infected plant to my local extension agent for a confirmed diagnosis before I pitched it) After you cut the leaf you can tell if it's bacterial by breaking the leaf (it should be soft and mushy)and smelling it. If it's bacterial it will give off an awful smell. If it's viral it woun't smell at all. Really hope I'm wrong on this.

    Thanks ischel, the leaf is not mushy at all yet. Maybe it's different inside of it though. How do I find those orchid doctors here in Canada do you know?

    Try googling County Extension Agents in BC or Agricultural Extension Agents in BC, that's where you are right? And if they can't help you maybe they can point you in the right direction. Or you might try sending emails to some of the Commercial growers on the net and attach a pic and beg for help. But I think that unless you put the leaf under a microscope....ahhhhh just had an idea. Do you have any universities near you with a bioscience dept, agriculture dept or hort dept. Maybe you could beg them to look at your plant. Unless you can get a definitive diagnosis you're going to have a dozen different opinions.

    After I got home yesterday (Thursday) I looked at the plant, when I picked it up the leaf that was damaged the worst just fell off by itself. It looks like the plant discarded it like you said (just above the p-bulb). The bulb looks fine now, that said, I think some of the other leaves is getting brown spots too. Time for an intervention.

    Time to arm your weapons and spray with fungicide!!! I don't know what else we could do since it seems to be spreading. I don;t think it is a virus since it is spreading so fast. Virused symptoms usually occur on new growths.

    I think I will be buying some virus tests but I won't need many of them for most of my orchids since slippers rarely get infected because of their way of propagation. Just nice things to have around... I already disposed of a pretty catt with colour breaks in two bloomings without doing a test to be positive with that it's virus.

    I just blasted my collection with a systematic pesticide to get rid of those darn mealy bugs, which came from a reputable grower ironically. This is my third application. First step in virus spead prevention is to keep sucking bugs from crawling from one plant to another. I was usually against the use of pesticides especially when I had few plants, but with a growing collection it is impossible to contol by picking them off by hand now. Funny after spraying they all come out as if they are looking for a new plant.
