    Angry Scale Wars

    After discovering scale on my Phal. Brother Sara Gold Friday night, I spent the weekend scrutinizing and scouring my entire collection. The final infestation count was 1 paph, 11 phals and my Psh. Green Hornet.

    I am shocked and relieved (perhaps prematurely?) to discover that it had NOT spread further. The green hornet was on a completely different shelf from the phals. Maybe it is a coincidence that it had them or maybe that just confirms my speculation that the Cygon I sprayed on everything outside last fall has protected them? I got the Green Hornet last spring and it sent up consecutive blooms all summer, so it never made it outside and hence was not sprayed.

    Frankly, I am mortified that I didn't notice the scale sooner. Three of the phals had obvious problems with limp leaves and stunted new growth, that couldn't be explained away by my root-killer history. These have been unpotted. I'm not sure if I should unpot the others--they all appear to be in good shape and 5 of them are in spike. I have scrubbed off every visible scale with alcohol, sprayed the media with alcohol/dish soap/cinnamon oil mix, and isolated the victims in another room.

    I did not see a single crawler stage scale, they were all the dots in various sizes. I'm not sure what my next strategy should be. Is it worth spraying a pesticide now, or do I have to wait until the eggs hatch? I have some Bayer 3-in-1, or I could get more Cygon from the farm, but I am not jazzed about using it inside the house.

    I intend a take-no-prisoners war and I would love advice on how to stage the next offensive.

    I just found the same on two of my paphiopedilums.....went crazy with some rubbing alcohal...now its just wait for the straglers...lol..........i dislike scale seeing that you cant see them.......i find alcohol and a Q-tip work getting them off and then it just evaporates...they like dry weather so i keep the plant moist, and follow up with more swabbing or if you want see any..then a 1 part alcohol and 2 parts water and mist lightly with a good fan blowing on them....seems to have worked in the past for me. I dont have many bug problems either.

    I too have had good luck with nothing but rubbing alcohol and qtips (or once a toothbrush, when some were pretty stubbornly attached at the base. I do it 2-3 weekends in a row, and usually, but not always, I spray with a diluted neem oil mixture after the cleaning. Usually takes care of them for me.

    Scale on orchids is so hard to get rid of completely. Good luck to you.

    cheers,

    I normally use a toothbrush and dishwasher liquid - but they are difficult to get rid of.

    I had to toss a L. tenebrosa. I never could get rid of the scale. I had it for years and one day... ::: poof ::: scale. I did everything I could and it just came back worse each time. I tossed it with a heavy heart.

    Variety of answers! I know there are different kinds of scale...maybe that accounts for why sometimes folks have more trouble getting rid of it, or maybe it has to do with how advanced the case is??

    Anyway, good luck--I hope yours is not a difficult case!

    I personally rely on lady birds when it comes to scale or aphids; works without chemicals.

    Thanks everyone. Kathi, I sure hope you are right! I feel sick when I think about how much rearranging (and cross-contaminating) I have done in the past few weeks as some of these phal spikes outgrew the shelf they were on.

    Gurj, This is soybean country, so we have tons of Asian Lady Beetles in the summer time. Last winter there were a couple in our house that I managed to keep the rest of the family from squishing, but I haven't seen any inside this winter. I'm not sure where I could scrounge some up in January in Iowa.

    Kassie: I have used "horticultural and dormant" oil spray for a number of years with great success. I've used it on mealy bugs and a couple of kinds of scale, including the particularly nasty boisduval scale. When I find one little critter, I spray the entire plant. Keep the plant out of sunlight and high temperatures for the next 24 hours.

    I looked at your other thread and I agree with someone there that this may not be Phal. Brother Sara Gold. I've got one as well and it looks nothing like yours. None of the images on Orchidwiz look like your plant either.

    This is a thread that has an image very similar to my plant and the Orchidwiz images:
