Helllppppp!!!!

[ysanabria]

Can somebody let me know what happen to my orchid??
It has been cold and very windy lately in Miami Beach, I have never seen this before in any of my plants. Can it be the cold?

[Tarad]

Wow, I will shut up on this one, I am not familiar with the culture of this one but I sure can say OH CRAP for ya.

[Irene]

Wow I don't know. Has it been ravaged by bugs?

[fred]

its a bit hard to say as the images have gone
once the images are deleted or moved in photobucket the link is broken the images will no longer stay on the forum unless you upload directly from your computer via attachments ( see link http://www.orchidgeeks.com/forum/new...675480c4deb032 )

[Celcat]

Fred,

ysanabria must have moved the pics. They were there and worked fine just a while ago, as in a few hours ago but not now.

[Tarad]

I see them Kevin?

[Tarad]

Yep now about a half hour later now they are gone.

[11Orchid126]

I see them. It looks almost as if they've been sprayed with a chemical of some sort. Was anything being sprayed nearby and the chemical could have drifted over to your plants? Is it only on the tops of the leaves, or all the way through?

[ysanabria]

Fred I cant access the link.
I dont know what happen with the pics? I will try to post them again!
Thank you

[ysanabria]

[ysanabria]

11Orchid not chemicals what so ever I have other orchids very close to this one as well attach to palm tree and they are fine.
Even the new growth are showing the same spots

[ysanabria]

[ysanabria]

Its producing a lot of new growth and was fine a while ago! HELPPPP!!!

[Dendian]

Wow, that looks really sad.

Did it get wet and then cold? It looks like some areas were "protected" and the furthest out areas were hit the worst, so I would say mechanical damage of some sort.

Did you get hail? That's sort of what it looks like. I would also like to see a picture of the bottom of the leaves, it looks like ones that are curled downwards are not affected either, so something that came from above....

[Dendian]

Oh, yikes, I just saw the picture with the undersides of the leaves. Did you spray for mites? I have seen some sort of damage like that caused by a mite attack. Some mites do not have webs... isolate and spray!

[ysanabria]

[Ben G]

Virus?

[LouisW]

Yikes!

It really does look like it was splattered with something toxic. Acid rain or something. Its strange that all the others are fine though.

How fast did this happen?

[ysanabria]

They only thing that have been unsual it had been very windy lately and we had a couple of weeks of very cold front at least for us in Miami.
Very close to it a have other orchids not the same type but they are Thank God very healthy!
I have not change the fertilizer, water conditions or anything that I can think of.
It has at least 5 new growth now and I checked the roots and they look healthy!

HELP!!

Yes have been wet and cold No hail. I will post some pics tomorrow from the bottom of the leaves

Hi, I believe you live very close to the beach ? If that is the case I would think that the marks are from sea spray. Seeing it's been very windy the salt from the sea has burned the leaves.?

[dounoharm]

thrips or mites of some sort?.....get the insecticide out!

Yes, I live on a house on the bay, but this plant is far away from the sea and I have others very close to the sea and they are fine


HELPPPP!!!!

[kmarch]

This one is a challenge. After giving this a few days worth of thought, I think I'm of the opinion there is more than one thing going on here. Here are some thoughts and some questions:

I think nenella's theory that it could be damage caused by salt spray is an interesting one. The fact that other orchids are growing closer to the sea without damage is only relevant if they are exactly the same kind of orchid. In the wild some orchids grow in coastal areas near the sea and so have evolved with a tolerance for salt air and the occasional sea spray, so some orchids are likely to have a higher tolerance for such conditions than others. If nenella is right and it is salt damage this would explain why one orchid gets damaged while another remains unharmed. The damaged orchid looks like some sort of Oncidium Alliance plant, possibly a Brassia? Do you have any more of these growing out in yard?

I have heard many reports here on the forum about how much colder than usual Florida has been this winter. The patterns of light coloured spots, to my eye, seem similar to dew droplets. Is there any chance that this orchid was exposed to a very cold overnight dew or a frost?

Finally it looks like there might be a bit of a fungal thing going on too. I'm referring to those rough darker browh patches on the leaves and pseudobulbs. The fungus mat be taking advang=tage of the damaged and weakened leaf tissue.

I'd treat the whole plant, spraying all leaf surfaces, with a good fungicide and then watch it carefully to see how it goes.

How long has this orchid been hanging on this tree?

[orchidlover55]

I would just spray them real good with 3-in-1 Safers Spray and then again in a week. That would take care of bugs and fungus if that is the case and it won't hurt them even if it's not. I don't know why I am asking but just a hunch , is the leaves the same underneath as well as the top? I don't want to say for sure but you do look like you have a mold problem on some of it. I would just spray to be safe. The white dots on the leaves really look like some kind of bleach or something. Has someone cleaned around the house with bleach?

[willowbanks]

Ysanabria, that's got to be the best or should I say worst mite attack I've seen in ages.

We have the same palm out here in Australia and call it a Golden Cane Palm, they are notorious for harbouring mites down in the frond axis against the trunk of the palm.

Treat the palm and orchid with a systemic pesticide and every thing should return to normal.

[lmartiny]

I've followed this, and now can see the pictures. Ouch. I had some funk stuff going on and am trying to be more diciplined with 3 in 1 systemic. I hope you get ahold of the problem. It is frustrating.
By the way, does anyone know if a systemic will stem snails? I found two baby snails on plants in the GH today. Not good.

[kmarch]

This is one of the reasons why I love this forum! There are so many different people with different pieces of the puzzle. Who else among us would have recognized the kind of palm tree the orchid was mounted on and known they are notorious for harboring mites? Because the damage was so even all over the entire plant I had more or less dismissed the possibility of mites though it does resemble mite damage.

Orchidgeeks RULE!!! LOL

Regarding snails: I've been trying 2 different "natural" repellents: coffee and crushed-up egg shells. There are a variety of effective snail baits/poisons that I am told are effective but I have been reluctant to use them because we have a cat and our neighbor has a cat that often visits our back yard. I dont' want any harm to come to them. So I asked a bunch of my Aussie orchid mates and looked around here on the forum and elsewhere on the web and learned of these two deterents. Coffee grounds are supposed ot be effective because the caffeine apparently kills snails and slugs. So I have saved up a bunch of used coffee grounds and spread them around on some of my orchids that have been attacked. My experience with coffee grounds is mixed. It seems to have been effective about 80% of the time. I put it on 6 orchids. Two of them had a little bit of slug damage after I put it on.

The idea behind the eggshells is that their sharp edges hurt when snails and slugs go over them. I have 2 nobile-type dens that the snails have been after so I saved up a bunch of egg shells and crushed them up and spread them over the top of the mix of these two orchids. Since then, no more snail damage. It would appear that the egg shells are effective but I have only used them on 2 plants so I dont' really think we can say for certain they are 100% effective. Even so, with those 2 plants, the egg shells did seem to keep the slugs away.

Is an Oncidium, I dont have another Oncidium in my backyard close to the ocean, mostly Catts and Dens which they seems to love the wind and have no problem with the salt So this could be a possibility to the increase cold and heavy winds we have had in the past months.

I have heard many reports here on the forum about how much colder than usual Florida has been this winter. The patterns of light coloured spots, to my eye, seem similar to dew droplets. Is there any chance that this orchid was exposed to a very cold overnight dew or a frost?

Yes very unsual and cold weather for us for a very long periods that have caused a lot of damages in my plants but nothing like this one. Not frost but for sure cold overningt dew!

Finally it looks like there might be a bit of a fungal thing going on too. I'm referring to those rough darker browh patches on the leaves and pseudobulbs. The fungus mat be taking advang=tage of the damaged and weakened leaf tissue.

I'd treat the whole plant, spraying all leaf surfaces, with a good fungicide and then watch it carefully to see how it goes. I already start treatment!

How long has this orchid been hanging on this tree?

8 months.

I already start treatment with 3 in 1!! The leaves show more damage in the top but you can see them as well underneath.
The plants is mount it ouotdoors in my backyard, no bleach or chemicals at all!
Thank you for your help!
