yellow spots on the back of the leaves

[marcecarloh]

hello!! I have a dendrobium that is blooming! but today I noticed some yellow spots on the back of the leaves. the flowers are gorgeous and the plant looks ok. a few months ago my orchids had red spider (spider mite) but this is controlled now.
those 3 photos are the same orchid. please help me!

It does look like something has been sucking on the leaves, but I don't know what it might be - hopefully someother members will be able to help out!

anyone have any ideas/opinions?

It looks like it might be ring spot virus. I sure hope not. Isolate immediately.

[marcecarloh]

it can be a virus even if it´s blooming?? how long I have to wait to be sure???
i´m really scared now

[marcecarloh]

please help me with a web page were I can buy some strips for testing that virus so I can bring it to my country.
and please give some advice about how to recognize viruses. I have about 100 orchids and I don´t want them to be infected. are my babies

It just looks like something was sucking on it. Ring spot looks different. Larger. This just loks like meanical damage. Isolate it just to be sure and if it doesn't get worse in thenext week, I wouldn't worry about it. Yellow jackets and other wasps make holes in soft leaved plants. Are all of your leaves like this? Is this damage just on the leaf tips? Are there more every day?

[marcecarloh]

not all of the leaves have that problem. I think that problem has been for a while, I already isolate the plant and i´ll be watching it for a week. the problem now is that 3 flowers didn´t bloom, like they get dry i´m not sure.
the damage it´s not only on the leaf tips, but the worst leave it´s the one I took the picture

it has been almost 2 weeks since I post that photos and my orchid leaves looks exactly the same. so can I say it´s not a virus??????
