    Can you share pictures of the plant infected with fusarium?. It requires treatment with Thiomyl or something systemic compound that is similar.

    If you do, indeed, have a fusarium infection, I agree with Sriram that thiomyl, AKA Clearys 3336WP, is a good, systemic fungicide. Another alternative is a plant probiotic, such as Inocucor Garden Solution (AKA Synergro). While it is sold as a preventive treatment, which uses beneficial bacteria and fungi to predate pathogenic ones, I have used it to cure a few, nasty fungal and bacterial rots.

    Purple streaks are first signs, then they turn necrotic.

    Phyton 27 I think is a copper based contact fungicide based. fusarium would need a systemic fungicide treatment

    Phyton 27 is a copper sulfate-based bactericide and fungicide, and is systemic to a degree, but there are some orchids that find it toxic - mostly dendrobiums and "thin leaved" plants like lycaste, coelogyne, etc. I would also be wary about using it on small, Andean species.

    Physan 20 is a topical disinfectant based upon quaternary ammonium compounds.

    Thiomyl is thiophanate methyl, or Dimethyl-4-4’-0-phenylenebis-3-thioallophanate. It is systemic, and I have never heard of cases of phytotoxicity.

    with my other orchids that have fusarium I followed a girl on youtube and soaked each plant for 24 hours once a week for 3 weeks, each time with a different fungicide and my orchids have improved a lot! her name on youtube is ana maria at miracle orchids...
