    Jason, I agree with Bruce...scale really sucks and will infect the rest of your collection quickly unless you take preemptive actions.
    Malathion is good as a scale killer and is a good treatment for the rest of your collection. This is what I have done in the past...isolated the infected plant(s). Treated the rest as a prophylactic measure...The infected one gets new media, a new pot, and gets scrubbed down with a strong malathion solution with a toothbrush! If I had a cymbidium that was infected I just don't know what the hell I would do! I think I would do as Kathi says...take a division, treat it with a systemic & malathion (or the juice of your choice), scrub the hell out of the division to really clean it up and if you still have any energy left repot what is left of the cym with new media, etc.
    This has worked for me in the past. It is a lot of work but if you are really attached to the plant...best of luck with it!

    If you are planning to throw it, I would be willing to give it a good scrubbing. I hate to see plants die.

    I've had scale on my dwarf citrus trees before and I've found that spraying them with soapy water kills them.

    Thanks for all the input guys!!! I like Kathi's idea of keeping a managable portion and cleaning the hell out of it. Even though it isn't one of my precious babes, I don't like tossing it out.

    Do what you will - but I would drench it and soak the pot/roots as well in systemic. I would repeat for weekly for 2 additional treatments. If you are using a mix that is more like soil the systemic tends to stay in the soil and not wash out. I used this approach last summer and killed a load of scale.
