hi guys
what do you think this is? some sort of mosaic virus?

Not sure about mosaic virus

Not the same genus obviously but... wonder if something could be munching your leaves?

http://www.marinrose.org/fastfacts-virus.html

The first two pics exhibit "Ring Spot" virus and thats a problem. The 3rd pic is has a fungal, age and sunburn problem. If the pics are from the one plant, the third pic leaf is stopped from showing the virus by the sun burn and fungal/age issue.
The whole plant will be infected and there is no cure. This virus is also transferable to all other plants.

hi guys
it's a photo of the same leaf. i've checked photos on the interenet of the mosaic virus and they were somewhat all ery similar to this one.
there're no bug of anything else on the plant. it's flowering with 2 flowers and 3rd is on it's way. i'll keep an eye on it.

can it be transferred by air? i water it separetely anyway and it doesn't touch other plants.

Hi Kate

Can you say which Genera this plant belongs to, it looks as though it could be Coelogyne?

Cheers Chalkey

hi Chalkey

it's lycaste. another one from that unfortunate bunch from Jacky Orchids

I agree with the others Kate, it looks very like a virus as long as you keep it seperate, water seperate and wash hands/equipment between plants to stop cross infection you will hopefully be ok.
btw is it just me or does that look like a face staring back at me from the leaf? (2nd pic top left)

(don't show me any ink splotches or I'll be here all day )

Hi Kate

I grow the odd Lycaste, and sometimes get marking on the leaves but never as bad as on image 4320 I would keep a serious eye on this plant. Lycaste tends to be deciduous so leaves go pale and yellow before dropping but the ring marking looks like virus. The choice is yours either to destroy or isolate!

Cheers Chalkey

thanks Chalkey

apart from these markings plants seems to be doing well.
and it is not spreading fast which is unusual for a virus. but rings definetely look weird...too perfect? if you know what i mean....

hi Tanis

can it be transfererd by air?
it doesn't touch anything and i water it straight from the tap so hopefully it'll be ok...

Hi Kate,
Not according to the University of California

'All virus diseases are propagated with plant. Once infected, plant remains so for life. Destroy infected plants. Disinfect tools between cuts or heat‑sterilize in a flame.'

this is the website that the quote is from.

Cat

well, if it isn't transferred by air then there's no immediate danger for other 2 plants next to it

i just want to see how it turns out. also i'll send it back with other dead plants to Jacky Orchids when i get a chance to call them

You folks quite sure it's a virus???
Looks cultural to me, but who am I to say.

Look at this link..

If the plant is growing normally I'd personally be inclined to give it a chance to grow out of the apparent 'condition'.
But a bit of common sense hygiene when watering (ie no communal dunking or suchlike) should contain the risk somewhat.

hi Alec
very intersting found
i wonder if it is possible to check the virus at home? this ELISA test or similar in the UK?

this spots affected only 1 leaf so far but the other one on the same (last year) bulb is heading the same way. leaves on this year bulb are ok so far

Hi Kate,
Sorry about your plant. This is always such a difficult decision to make.
You can get kits such as this one http://www.pocketdiagnostic.com/products/21. The problem is, as far as I know (please correct me if anybody knows otherwise) tests are only available for CymMV and ORSV. However there are countless other viruses you cannot test for. So you will never know for sure.

thanks Galina

i think i'll give this plant another chance

Unfortunately there is nothing cultural that would cause this problem. The type of virus it is, isn't one that spreads and takes over every part of the leaves. It may only show in a few. Virus can be spread by hands, cutting tools, potting benches, pots and still under discussions over many years, insects and water splash. Any plant with virus in a collection has the potential to affect every other plant AND can be transferred to garden plants. Many collections of orchids have been ruined by that one favourite plant being kept. Every orchid you have now or purchase in the future is at great risk of contamination regardless of how careful you are.

Ay Caramba!!!!!

oh well, ok, i'll send it back to the vendor to enjoy

if anybody interested - here's more photos of non-virus related "beauty"

I am not convinced it is a virus , but obviously could be so be cautious as already suggested with cutting tools,pests ,watering etc .
Then i would see what new growths do after it has been in your care for a while , if the markings keep occurring then i think i would cut my losses and get rid.

I have a Den speciosum that got black pitted marks on the new leafs every growth which was frustrating as they looked good then pitted , after a more consistent feeding/care regime over a couple of seasons the pitting has stopped .
So you never know

I to have a Paph that looked as if it had either an insect or virus problem, but all the new growths are clean, the old one still has the marks and I never did find out what it was.
I just kept it seperate for a year untill I was sure that the new growth was clean and free from anything and I have not had any trouble since.

I do have a couple of plants that look as if they had virus (oncidium) and it turned out to be leaf burn. I have had one plant that consistantly had a leaf problem, but as it was a noid I was not too worried and I kept it away from my other plants (it was one of the losses when I was away for a month)

I believe that all plants carry the virus, but stress from transit, condition changes or damage to the plant can make a virus active, but that is only my oppinion.

I don`t think virusus are too common so think we should look at cultural conditions first and a virus is difficult to diagnose unless you get a sample tested .So you have three choices get the plant tested ,throw the plant away or isolate,be careful and nurture it and see what happens .

Hello

A little heads up, i have had that mark befor on an orchid. it was a zygo. it had scale insect and i used meths to kill them. were ever i had treated that sort of mark came a few days later were it had damaged the cells. i never did see the markings again on it not even on the new growths. it sadly is no longer with me (forgot to turn heater on in greenhouse and it got frosted)

always still be carfull with orchids you can't explain the marks on. isolation is the best thing to stop spreading. if the marks do keep growing in to the new growths then worry.

hope this helps

hi guys
i've done testing for cymbidium mosaic and "rings" viruses - both came out negative but will keep it away from the rest of my orchids.

the 3rd flower is now open and all of them (3 in total) are looking nice. although i haven't heard from the seller about the virus and replacement for the other 3 dead plants.

if it is a virus - it doesn't look very dangereous... I think I've seen on my 1 or two plants long time ago similar rings and it didnt spread around, but it my be natural resistance in some species for some maybe it is more dengerous...

regards
