    Thank you Ian!
    I wish i waited few hours to repot it!
    So would you suggest to unpot it and soak whole thing? or maybe just spray with fungicide to reduce stress (im sure i already stressed it a lot )

    Sorry Svetlana. I did not notice the brown marks on the pseudobulbs. I suggest you unpot and soak in fungicide (cleary's). Physan is contact only and not systemic. From what I know, catestum are quite prone to rot and could be a problem.

    Thank you Ksriram,
    Will go to store today than to buy any systematic fungicide, i dont think they sell cleary's in store so if i buy online it will be delivered in few days and i assume i dont want wait for few days. Or mayne i can check active compound and see if i can find other brand with same stuff.

    ---------- Post Merged at 06:04 AM ----------

    Will it work if i turn pot upside down and soak only foliage?
    In case if roots also should be soaked can i just soak whole thing with pot?!

    If its cleary's should it be deluted? If so do you now how much? Obviously i dont have its instruction but label says its 40% thiopanate-methyl so i should be able find other brand but im not sure with same concentration. And i doubt cleary's should be applyed at 40% of active compound.

    My ready reference is Sue bottom's guide. it says 0.7-1 tsp/gal of Thiophanate methyl alternatively you can also use either of these
    Banrot -- Mix of Etridazole (contact) & Thiophanate methyl (Systemic) -- 0.5 to 1.1 tsp/gal
    Zyban -- Mix of mancozeb(contact) & Thiophanate methyl (Systemic) --0.75 to 1.5 tsp/gal
    Subdue maxx -- Metaxyl -- 0.5 to 1.1 tsp/gal

    You should drench the potting media and the foliage. If time permits, you can unpot and soak the pseudobulbs for 10-15 minutes.

    it is ok to unpot them and treat with fungicide again, as long as you are gentle with the roots.
    it is better to be sure to be rid of the infection in order for the plant to strive

    Ok, so i mixed three available fungicides and soak plant in it.
    There is some white residue due to its not dissolve in water completely.
    Do i need to rinse it in water after that? Sonething tells me not to since ir will wash off the fungicides from plant surface. Am i right?!

    What are the 3 fungicides?. I hope you checked thier compatibility before mixing them. IMHO never mix fungicides unless until they are compatible. From what you are saying may be it WP (Wettable Powder) which does not always mix well in water or is it precipitation due to incompatibility. I am worried.

    Good point Ksriram! No i did not check compatibility too bad for me as I should have check it being chemist LOL. The three fungicides are benomyl ( took from work as a powder) than in hardware store found daconil (chlorothalonil) and liquid copper fungicide. That all they sell. I bought also product for lawn fungus control with thiophanate-methyl, its granules and has 2.3% active ingridient. I sought i bettee delute liquid concentrates , than granules. It was late yesterday alredy, i had to do buy something for my son for school, they celebrating some sort of international food in school so teachers ask to bring characteristic bread or dessert from the country you are from. Well he was born in US but he knows his parent feom other country. So to get bread we drove to NY city, and then went to hardware store and by the time we got home i just wanted to be done with soaking.
    Should i start over?!

    Sorry about that Svetlana. From what I can see, benomyl is systemic and chlorothalonil,liquid copper are contact fungicide. I see some non orchid references of recommending benomyl+ chlorothalonil and benomyl + liquid copper but not all three together. Hope they don't cause a problem. I suggest you monitor symptoms on the plant closely and redo only systemic if required.
    typical instability related symptoms would be burn marks, edema of tissues, discoloration, dropping of leaves.
    I am keeping fingers crossed. Hope it does well.
