Paphiopedilum henryanum with brown spots on leaves

[tdeprat]

Hi!

I recently got a paphiopedilum henryanum on flea-bay from a chinese vendor. The roots I thought looked okay. However some of the leaves have these brown spots that I have attributed to mechanical damage. But I am not sure. Hopefully someone with more experience can help me out with this mystery diagnosis.

The last picture shows the other leaves that look better.

Thanks!!

i dont know what to tell you but that must have been a long time shipping so anything could have happened before or after shipping....maybe it is from some chemical they sprayed it with before shipping?? that would be my guess.....gl

you might try and wipe the spots with a damp paper towel to see if its just junk on the leaves (perhaps its just dust from the packing that clung to water droplets on the leaves then dried there during shipping),...perhaps if you mist one of the leaves a bit to see if that helps soften the stuff on the leaves..if they dont come off then it very well could be some kind of disease, you could try a mild fungicide on them but im not sure how sensitive paphs are to such chemicals...there are some organic fungicides that might be milder...im no expert, but thats what i would do.

btw i would love to have one of those, been looking around, they are not easy to find....i think i even spotted that one on ebay.

The news is that things are worse!!!

I now have black/brown spots on all my office orchids. Some tiny tiny spots, other bigger. Some leaves even look "scarred" even though there are no black spots per se, just recessed parts of the leaf. Anyhow, I took pictures and will upload them on my next post from my phone. The thing is that I don't know if they are related because I saw tiny black dots on the leaves that I thought were just like sunburn when I got them. (This is why I don't trust the 'bay.) Sometimes you get what you pay for and sometimes you get worse than what you pay for!!

Anyway, I just went crazy and decided that I had to take immediate action because I am going to be out of town through Wednesday. I also didn't have my car with me, and can't go back in after I leave if it is past 6pm as my badge won't work during the night shift.

I went all McGuyver and assessed what tools I had on hand. Paper, alcohol wipes, Purell, scissors, bathroom soap...and then I remembered we have a first aid kit that has triple antibiotic ointment.
I casually walked over to the first aid kit and raided the triple antibiotic ointments and brought a bunch over to my desk. :

I wiped down my scissors with alcohol and purell between plants (and cuts actually) and cut off some of the parts on the plants that looked worse for wear. I also slabbed on triple antibiotic ointment on the leaves that were affected and on the leaves that I cut.

I probably left the ointment on for about an hour, then wiped them down as to remove most of it.

Hopefully it will help since the plants are at the office and I am going out of town till Wednesday. I'll keep you guys updated too. I should have taken pictures of what I am now referring to as "the blight" afterwards.

My guess is some sort of fungal infection.

I need to learn to see things better. What would make it look more fungal than bacterial?

The sad thing is that I can't go back till Wednesday, so I'll probably pick up something at Lowe's over the weekend and take it to work next week. I just hope it isn't to late :-(

Any specific product that would be recommended?

Guignardia/Phyllosticta fungal infection. Spreads by spore from an infected plant. They are the same infection just at different stages of development. Raise your light levels as high asyou can, and keep leaf surfaces dry. Spray with a fungal spray. Keep the plan as dry as you can. I know that these need to be kept somewhat moist but do what you can. They could also be a microfungus of which there are hundreds. Try the fungal spray. I don't know wha is available in your area. Here in California they have banned nearly all fungal/bacterial/inscticide sprays. It's a wonder they haven't banned air.
