is this a fungus or a bacteria???

[andreaemilia]

Hello everyone!!
this summer one of my phals developed this infestation/infection
it seems to be limited to only one plant but it attacked the developing keikis too, though they seem to be growing at similar rate as the other keikis (I got at least 20 keikis this year)
I sprayed it with a broad spectrum anti-fungal agent ant it seemed to stop for now
I could use your advice


another plant has this discolorations on the backside of the youngest leaf. I wonder what it is???

Well it does not look like bacteria or fungi but like spider mite or false spider mite damage.

ok
I didn'i see anything crawling on the leaves, or are they microscopic size?
and what to do about it?
if anyone can tell me some home remedies, or something non-toxic
My house cats visit the orchids on daily basis I don't want them intoxicated
And should I quarantine the plant or even destroy it??

I've had great success with cold pressed Neem Oil. just follow the directions for mixing and add a few drops of non-anti-bacterial dish soap (like regular Dawn) and you should be ok. I would quarantine the plant for a while also...

Thanks
I will try that

Also, since I will buy the Neem oil from my bio cosmetics shop I have no ideea if the instructions apply for orchids too
Could you tell hou mixed the Neem oil you used?
Thanks again

1 1/2 Tsp per 1 quart or warm water. Add about 5 drops of dish soap, shake & spray...that's it...Good luck

Be sure to increase humidity around this orchid. Spidermites don't do well in humid environments.

cheers,
