    Default scale?

    On my 'ol reliable' phal, I'm pretty sure this is scale - my first exposure to it

    I've had this plant forever! This is the first problem, poor thing. It was just under the bottom leaf, but on the flowers there were orange spots - it that how it begins?

    I destroyed the leaf, wiped down the others with rubbing alcohol, and (weeping uncontrollably ) cut the flowers off to destroy as well. Two weeks later, and there is still no sign of trouble.

    Should I have rinsed the bark with something as well? What causes this?

    Don't mind me Sarah--what do I know? But that doesn't look like the scale I've seen. Looks more like tiny snails?

    Some forms of scale develop a hard armor like in your picture. Most often I'll get the nearly transparent, softer bodied scale (closer to what was on your flowers.)

    I get it frequently, but if you treat it quickly, it's not much of a problem. Check any nearby plants, in case it hopped over to them. It loves to lurk on the outer margins on the underside of Phal leaves, but I've also had it on my Oncs. I've never seen in on Paphs, oddly enough.

    When I find it, I scrape it off with my finger and then spray the whole plant with Neem oil (a natural oil that's not toxic to people and pets.) I'll try and remember to spray the plant again in a week or so, just to discourage any critters from returning. No need to cut off leaves or flowers.

    Well, I sure learned something today, too. Those critters don't look anything like the scale I had before. Ick, ick, ick!

    Thanks Julie!

    No problem, Mehera, but I suspect there are folks more expert on this sneaky little pest than me.

    Here is som info. on them .Armored ScalesDiaspididae) Armored scales are found on the leaf, rhizome or pseudobulbs. Their presence may be indicated by a yellowish discoloration of the leaves. Armored scales do not excrete honeydew. These insects secrete a waxy, hardened covering that is not part of the insects body. The armor is nonliving and composed of secreted waxes incorporated with nymphal cast skins. This protective covering may be circular, semi-circular, oblong, or pear shaped.

    They reproduce under the shells , and are asexual no male female needed .
    Most of the Rose sprays will kill them , or Horticultural oil . They love Phals . Have to spray about 3 times . If only one plant alcohol with a dash of soap will get them . Even Canola oil 1Tbs. to a gal. of water with a dash of soap . Hope this helps a little . Gin

    Armored scale...terrific. Figures I'd get Rambo.

    So do you think the orange spots are soft scale? I had both???

    I have been careful to examine each day to see if they spread to other plants - so far I've been lucky, I guess.

    Thanks for the info!!

    Hi , they are the young armored scale they have not developed thier shell yet . Between the diffrent types of scale these are easier to get rid of, at least you can see them .
    I had them on Phals. several years ago used a Dormant oil spray I had for the fruit trees , it got rid of them , sprayed them at night so the sun would not cook the plants . Gin
