    Default How bad is this situation

    I have never run into this (these) problem(s) before. There may be more than one malady but it has progressed from one blc. I got to several chids of different types. It starts off as a translucent, silvery spot on a leaf progresses to tan , then brown then black and finally dead and papery through the leaf. Soon after the air roots dry and die and all the leaves and P. bulbs shrivel. The plants continue to put out new growth but they are all going terminal. The disease is attacking Catts., Onc. Psychopsis, Milts. Phals. Pots. and zygos.

    Have you tried any of the antifungal/anti bacterial products. Also need to look at the media you are using. In one foto it looks green, is that moss. If so dump it yesterday. Use an orchid bark mix. I know you have extension agents where you live and I would bring the plant in for a diagnosis. I could also be viral. Hard to tell unless you look under a microscope. Try googling orchid diseases and see what you can find. If it is viral the plants will have to be dumped. You could also contact Hauserman and see what they have to say. You also didn't say over what period of time this occurs. Viruses tend to be pretty swift in their progression, at least that has been my experience. I'm sure there are other folks on this forum that may have more experience that can help you. Hang in there.
    In any case I wish you luck.

    My guess would be mites. Especially when you describe the "It starts off as a translucent, silvery spot on a leaf progresses to tan , then brown then black and finally dead and papery through the leaf. "

    It has been about six weeks since the first plant __got sick. One of the onc.s had pretty bad root mealies at about the same time so I repotted a most of my plants, washed them all down top to bottom and have been using insecticidal soap regulary since.

    To find out if it's mites as Jenny suggested, take a wet paper towel and run it nuder the leaf. If the towel turns a rust or reddish color you've got them. If not then it could be fungus or bacteria. If it's been 6 weeks since start till now I wouldn't suspect virus, but you never know. Did you google it?

    No reddish or brownish stains on a damp paper towel. 25 of my 45 plants are affected. The only cultural factor that has changed is I stopped using chlorinated tap water and started using rain water.

    Rain water wouldn't do it. The pic of the pb that you poster looked like a virus I had on mine. Till you find out what it is I would suggest isolating the affected plants.

    My guess would be bacterial. Try Physan or a nice peroxide douse.

    I apply it full strength directly to the pot (i. e. pour it on). It won't harm your plants at all and is much safer (and just about as effective) as most harmful chemicals.
