Red coloration on Paphiopedilum - Suggestions please - Orchid Board

Hello Guys,

Please help me to solve this.. Photos are attached.

Recently I noticed the Red/brown colouration on my Paph. This paph is not identified, but a species one according to seller who collected from forest.
I am taking utmost care for this as it is from wild. It was growing good from last 9 months, but I observed this yesterday. I noticed small white (tiny) insects crawling on the media (coco peat + clayballs + humus). And immediately started inspecting every inch of the plant and I noticed this coloration.

I checked with the roots, they are good (strong and fluffy), it is throwing new roots too. I treated with Sevin. And then after some time with Physan+KLN+proteket (.25 ml per liter) and MSU (50ppm).

Gave KLN as I removed the plant from pot, to check health, so roots got little disturbed.

I do not see any insects now, and I cleaned every inch of plant with rubbing alcohol (felt it reduced some coloration).

I have two plants of this Paph, I am waiting for it to bloom to get identified. I suspect it is Dhruyui or some rare ones.

Thanks in advance ..,
Kaarthiik

Doesn't look horribly concerning, but I'm the "wait, watch, and see" type. Others may have an informed opinion otherwise ...

Wild collected plants seldom do well in cultivation. Many orchid species are also threatened in the wild due to over-collection and habitat loss ...

Hi ya

You're media sounds good, but its more of the air circulation I would be worried about. You're orchid looks to have Erwinia, which its best to dry it up a soon as you can. Something that works real well for me is 70% Isopropyl rubbing alcohol. I use a small paint brush and go throughout the leaves 2x per week when I see this on any of my orchids.

What brings this on is humid stagnet air conditions.
Do you have any set up?

What is "Dhruyui"? Do you mean Paph. Druryi? Where was this collected (the forest)? What makes you suspect it?

Hi All,

Thanks for your kind responses.

@WhiteRabbit, I was not aware that it was collected from wild until plants reached me. I figured that it was from wild based on wild shapes of some other vandas. I received by a mail order...
Here in India, tribals collect plants from wild and sell to neighboring areas at very cheap rates without knowing abt anything, really concerned about loss.

@Laggon - I have a evaporative cooler running 16-18 hours a day (leaving some time in morng), and the air circulation I think is adequate, any how I am making arrangement to get more air.. till I see the leaves moving.. I rubbed with alchohol.. will repeat next week.

@jeremyinsf - I just doubt due its growing style, loves light and its leaves seems to be Paph. Druryi.. And I am from India where is endimic (collection from Assam state of forest), And seller said it has yellow flowers!

Any suggestion would be quite helpful.

Thanks and Regards,
Kaarthiik

Druryi does indeed come from India, but only from a very small part of the southern most tip. Looks like Assam is quite far from that.

Here is a picture of my Druryi, if it helps:

To me the leaf pictures you show they look different, but then again, every plant is different anyway!

If you don't have any developing spikes now, it will probably be another year at least before you see a flower. It's season is already coming to pass. I have been told it can take new fans a couple years to mature before they will spike.

Best of luck!

@jery

Thanks a lot and lot for that pic. I am searching for the pics to compare mines..

I see some similarities in mine, like the leaf structures and newgrowths from the bottom of other growth.

Yes, Dhruyi is endimic to Kerala, but I seriously feel the research done on Orchids of India is not complete. They are distributed vast.. I see many instances of orchids in India, where the areas are not even listed anywhere.

I personally seen some orchids in wild in areas that are not even listed for any orchid.. More research is pending. And many people are to be educated, some phrags thought to be extent are seen recently, tribals and people near by villages are educated about them and ppl are now protecting them.. By not collecting and not disturbing..

Thanks again.

Small paint brush eh? That's why I love OB, you learn something new every day. I use a small paint brush to clean between my key board

but I guess I'll be buying another one today for my plants. Great tip
