    Default Brown Seed things--Scale or ?

    A friend gave me a bollopetalum this weekend that has strange debris on it. Part of it is little oval brown seeds that are lightly stuck to the leaves, scrape off easily and hold their shape when wiped off. They are all over the leaves and especially at the leaf junction. Also at the leaf junction are little shavings that look like curled shreds of tissue paper. I am envisioning some exotic bug molting its wings.






    Of course it is blooming right now with 2 spikes and I love the color, but some blooms also show bug damage. Evidently there is a critter problem where it came from.

    I know the one pic also has some sort of fungal/rot issue also--I'm not terribly worried about that as I have never seen a zygo of any kind without some blemish on the foliage. But the seeds/molting freak me out. I've read everything I can find on scale and other pests and don't see anything similar and I don't want to take any chances--so far my worst indoor pest has been fungus gnats and a few tiny snails. What is this and what should I do about it?

    yes, it looks like scale to me. Use alchohol/ethanol to remove them with a cotton bud. The shavings i am picking are from the previous owners environment, possible they did some planing of some wood or perhaps a little critter in a tree above where it was growing? definitly not wing moults or exoskeleton moults. I see also that the leaf in question with the shavings is an older leaf. There would have been a larger leaf encompassing the single one left, and sometimes in the cavity between them, debri collects over time. And for the fungal infection, cut the leaf or break it off below the rot, and then dip the wound in cinnamon. Either that, or use Sulphur powder. Then if it keeps comong back, use a strong, water soluble copper oxychloride at half strength for 4 weeks weekly, then increase to 3/4 strength for a further 2 weeks, weekly. Always read the directions though, so you know how much the manufacturer reccomends in regards to half and full strength.

    Then after this, use a soluble orchid foliar fertilizer, or a few slow release fertilizer granules (i find the ferts formulated for orchids work best) , and apply weekly again, at half strength for 3 weeks, then every 3 weeks at full strength from then on.

    Sorry, Jordan, but that doesn't look like scale to me. I got a bunch of orchids from a guy that had scale and it was nothing like that. Do the little seed like things move? Have you tried washing it all off and see if it comes back? Could it just be seeds that got scattered on the plant when it was wet and therefore have lightly stuck to it? They almost look like celery seed from the pics.

    On our greenhouse visit we did on sunday, i saw some scale that was black with a white ring around it. Then there was a little tiny brown one, identicle to this here. There is also an oyster shaped one and a grey slate scale too.

    I was thinking carrot seed, but there's definitely an element of celery there, too. Maybe it's a new hybrid vegetable?

    They are hard and they stay that way. They don't appear to move. They also don't have that thin, flat ring around them that I associate with scale. This is what confuses me. I cleaned off as many as I could get, but digging the junk out of the leaf junctions where the pb still has all its leaves is going to be a trick. That first pic is not an old leaf, but is the one on the bottom of the pb that was the last to bloom. The shreds seem like bits of dried outter pb covering (not as heavy as wood) that has been somehow miraculously curled in spirals and hauled to the leaf junction to be used as a nest?

    Now that I'm looking at my own post, the non-seed spot closest to the upper left on the first photo DOES look like scale.

    Jonada, did you manage to get the scale under control and get those orchids home? I reread how you dunked them in malathion and cleaned them off with alcohol--did it work or did you have to do more?

    Jordan, I'm going to have to figure out where to get copper oxychloride around here. I've seen you mention it before and my current rot-control method of sprinkling a little cinnamon, spraying some Physan and crossing my fingers has been mostly useless. My Ctna Why NotX and my odontoglossom continue to slide downhill and part of me wishes they would just die already.

    looks like miscellanous rubbish to me. just wipe/sponge off. if it was scale you will see a little indentation where the leaf cells had collapsed after being sucked dry; in that case,there may be babies about, too small to see with the naked eye, and you will need more advice. Hwever, if the leaf looks clean after wiping, no problem.

    Ha-ha Patty! Ok, maybe I didn't mean it, don't cry. I am sorry about my WhyNot cross--I took it from such a gorgeous specimen to 3 ugly, stunted divisions. Definitely not one of my finer orchid accomplishments.

    But. . .
    The Odm. is a prissy thing who arrived seething about her travel accomodations and has been pouting ever since. I pleaded and cajoled and prostrated myself for a while with no result, so I decided to stop being so codependent and give her some space and patience. She continues to sulk. Every now and then she acts like she's coming around and throws up a new growth, only to snatch it back in a passive-aggressive snit. Really, I find her attitude exhausting.

    Geoff, I don't see any leaf damage under the seeds. I will keep it under observation. For now, it is staying a couple closed doors away from the rest of the group.

    Thanks, all!

    Kassie, Try setting your sulking plants outside on the north side of your house, if you can. Then ignore them for the most part...check after rain storms like last nights to pour off excess water and give them a look over once a week, but mostly just let them hang out on the shady side of the house for the summer.
