Yellow Rust looking spots on paph. - Orchid Board

LizB88 · #1 10-09-2014, 03:33 PM

Hello everyone, I got this paph about 3 weeks ago it had one flower open an a second in bud. after a week the second bud open, the plants lost one fan and soon after both buds.

When I bought the plant I notice it had small yellow spots on 3 fans, I mention my concern about the spots to the seller and pointed them out, but he he said that it was no big deal. I have bought many plants from him and he actually has very good healthy plants. He is one of the people I buy most of my plants from.

Once the plant started to loose fans I sent him a picture of the plant and when the top two fans started to go, I send him another pictures of the plant before I trashed it. Hes reply was to just trash it and that he would replace it with another wealthy one.

Still he could not tell me what it was killing the plant.
Some of the roots were rotted, but it had what appear to be healthy roots. Although this was my first time seen this kind of roots. They felt firm and had what appear small fuzzy hairs on them (don't know if that is normal for this type of orchid).

I have pictures of before and after, I am just curious to know what this could be. I have very healthy plants and this is the first time I see this type of yellow marks and because I could not find what it was I got rid off the the plant. I also don't think the plant was going to make it anyways.

So any ideas?
Thanks for your info.

The first 2 pics of the leaves look like some sort of bacterial or fungal issue. The later pics look like rot took over. The roots with the fuzzy hairs are what they are supposed to look like and if they are actively growing will have a white nub at the root end. Tossing it was probably the best thing for you and the plant.

- The pattern on the leaves is normal (not the yellow coloration). But they turn yellow as the plant takes out all the nutrients before naturally dropping it. But the whole leaf would slowly transition from the tip to the base, not normally with small spots going yellow....

- The roots are supposed to be firm and fuzzy with these guys.

- My guess about the cause for you plant would be a virus/disease, and then rot taking over. But I haven't dealt with any diseases with my paphs, other members will probably have more info on that.

Some of the roots were firm, but i did not want to try a save it, specially when I did not know what I was dealing with.
I did get rid of it, it was a nice noid, and I did get to enjoy the flowers for at least a few days.

I though as much when I bought it but I guess the seller had also no idea what it was.

Good to know that the roots are supposed to be fuzzy, and some were firm, but the tips were black.

I was concern that it was a virus and so to avoid spreading it to my other plants I just got rid of it. The good thing is that the seller stands by his product and he is replacing it with another one.

I for one dont think its viral at all.

Just got done repotting my Paph. Supersuk 'Eureka'. He had some rotness didnt see anything unusual. I dropped some cinnamon on those patches, I hope it works. Just did that this morning because they seemed to get a little bigger even with physan. I wondering if mine is rust. From tap water. Im starting to see some dark areas on leaves were they attach to stem. I'm hoping all goes well, this was one of prized guys. Its the only Paph I have ever had, not to mention when I bought he had the one bloom, after a few days he popped a sec8nd bloom on same spike.

I hope you are right, that is rust. Then you can possible treated. For my paph, It did not look like rust. The person waters with well water and the plant came with the spots. It produce double bud, but they did not last and the plant quickly when down hill, with in a week. So it could be a fungus infection or it could have being viral, either way I think it would not have made it.

Hope you have better luck, how do you treat rust on a Paph?, I know that on cims and onc I can use a diluted solution of rose plant spray.

You can use the same spray Liz

I don't normally dilute rose sprays (insecticide or fungicide, usually I use bayer)

I have no idea. It's the first time I've run across rust on my orchids. I guess you were to treat it like a rose maybe dilute the solution little! I'll throw a thread up later on what the consensus would be on that. I first saw those patches they were coming to wish that's what made me think that it was Russ Lynnwood to me too what up what would look like my patches. I don't think I posted a pic let me post a pic.

Pictures #2 & 3 could be mite damage or rust disease.

The last two photos show the plant is basically dead.
The base of the plant and most of the leaves are consumed by rot.

I don't think the two are related.
The rust disease usually go away once you cut the affect area off early one.

The rot is a different issue, especially when it starts near the base of the plant.
When you discover that there is a rot on the base, that is usually too late and the plant is unsalvageable.

Wash your hands well after handling this kind of stuff or better yet, next time, you might want to use disposable gloves.
