Orchid Disease - Bacterial Brown Rot, spotting, treating and preventing
Tips, Tricks
Sick orchids are not a topic we like to talk about, but it is very important to know how to spot, treat and prevent illness with orchids. Today we talk about bacterial brown rot. The cause for this is, in most cases, water left standing inside crowns, new growths and in the places where the leaf meets the stem or axis of the orchid. They start as a wet looking spot that progresses pretty fast as days go by. As the wet patch extends, a brown coloration starts to appear and the leaf may start to yellow, spreading more and more and trying to take over the leaf. To treat this we need to cut the entire affected portion, cutting into healthy tissue so that the disease doesn't reoccur. It is also advised to use a bactericide or fungicide, but if you are not ok with these substances you can use hydrogen peroxide 3% from your local human pharmacy. This is not as string and efficient as a fungicide, but it is not toxic and it does help. To prevent this diseases we need to avoid water left on leaves, crown and new growths, so when watering your orchid you need to make sure not to splash it on the orchid itself. Use fans or keep your growing area ventilated, most of the times this will prevent a lot of bacterial and fungal infections.

Hi Danny, sorry to boder you, but I need your opinion. Like four weeks ago, I started to notice this spot on one of my orchids leaves, it is brown surrounded by yellow, it started on the tip of the leave. I think is growing slowly, I know I saw another spot more in the center on the same leave. I have another orchid and the tip is yellow. At the beginning, I thought it was sunburn or intense light damage, so moved them away from window (South face and sun is coming back) then thought it could be spider mites, but only this leave has the damage, I've been spraying a solution with water, dish soap and alcohol and don't see that is working. Can it be fungal infection? I am attaching a link to photo bucket so you can see, but the lesion is now bigger and more brown. Thank you Danny. I want to save this orchid and don't want the problem spreads to my other phalaenospsis.

Here are all the pictures I have with problems in leaves. I would like to know what is causing it, if I am doing something wrong or what can I do to stop from spreading or happening. Thank you Danny

Hi Dani!!
Thank you again for ur videos!! They are the best!
I have a question for u! I have a sick phalaenopsis. I would say that I'm dealing with rotten stem. One of my leaves turned yellow (that was when I realize that something was wrong) I treated her; cut the rotten roots, peroxide, etc etc.. I've been watching her the last week and I see not progress the leaves are still floppy (green) and anytime I spray peroxide in the stem I got this white thing that means there is still infection.. I know rotten stem is the worst kind but do u have any idea what's going on? Why the infection seems to don't go away? Maybe should I wait little bit longer?
Thanks!!!!

Hi Dani,
Great videos. What should I do if the infection is on the pseudobulb? https://instagram.com/p/BJSDeuDjMMh/ I have repotted in hydroponic media expanded clay pellets with just a bit of miss for hydration and humidity. I presume this infection is bacterial? The mark has been on the pseudobulb for about 6months and not gotten any bigger after being treated with hydrogen peroxide. The orchid hangs outside under the canopy of a Chinese orchid tree which I prune and train into an umbrella shape specifically for the purpose of hanging my orchids. I live in hot humid Hong King. Thanks for your Chanel. It's incredibly informative and makes following this wonderful hobby so much easier. -
thanks a lot I already have hydrogen peroxide but still looking for cinnamon...do you have a facebook account for me to ask for help easily??
-
that liquid you spray to disinfect bacterial disease is that alcohol

Hi Danni, thanks for this. I suspect my orchid has quite a severe case of Brown rot but i do not want to remove all the leaves before i'm sure (it's spread pretty bad on 3 of 4 leaves while 1 leaf is turning yellow. the stalk seems to be getting spots as well, however it's still growing new flowers. can i send you a few photos before I start cutting? thanks

Hi, I am going to receive soon a chysis bractescens, because I had one and it was performing so well for me. But I have a question, though: what is the care you give it during winter time? I don't know if I should treat it like a cycnodes or, instead, if I should never allow it to go bone dry or whatever. lol Thanks for the answer in advance. :)

I usually just drink the alcohol and use fire to sterilize my scissors. You should see my orchids! LOL! Just kidding... I don't actually drink rubbing alcohol.

Not sure I should do this, but this was passed on to me without any indication that it was private so I will share. http://www.phelpsfarm.com/OrchidPestsandDiseases.pdf Check it out, it's got some useful info.

Very helpful technique in caring your orchids. Thank you for your great advice.

One suggestion: hydrogen peroxide should be stored in an opaque bottle to prevent oxidation
