Gloria Naugle Fine Black Spots on the Underside

[Erythrone]

Sorry, I'm in New York City.

Thanks for the info about the magnifier. So with this one, you can see broad mites?? I have a very good vision and I do not consider spider mites small.
just for comparison.

Actually I saw flat mites very well! And I read 20 X is a minimum for broad mites.

I sprayed them last week but they have no negative effect from floramite yet. They look perfect. I was very carefull not to dose too strong.

What product did you use?

I bought Floramite from ebay and you can get 2ml bottle for around 15$ or so. Regular stuff for insects don't usually kill mites, so a miticide is the product to use. There is also the product called Sucrashield for those who prefer a more ecological solution. I went with the big gun

There are a few miticide products available on ebay, and floramite seem to be safe for plants. The instructions on the bottle said .3 to 1.2ml but I used .7 just to be safe.

How did you plant respond??

I sprayed my older one with this same symptoms, and guess what!
In just a day two, the spotting got much worse, and a few more days past, the leaves started to yellow, brown and completely blackened, dried up and died. well, two or three bottom most leaves died.
The surviving leaves had such ugly underside and I just got rid of it.

Thanks, good to know!
I'll look into it.

Wait, someone mentioned broad mite.
Are flat mites also microscopic?
Do you know what the damage of flat mites look like??

I believe it was Safer brand and the label said it covers mites.
Well, it definitely covered the plants as well. lol

I just looked up Floramite and I'm a bit scared. It says you have to wear PPE and do this and that.

I have read about Sucrashield, and it seems safer (for me) but not sure how effective it might be. Have you used it?

Really? I just brought my plants outside and sprayed them not even wearing gloves. I washed my hands well after. The plants show no sign of dammage from it so far.

If you are afraid of chimical, why not use Sucrashield? it is said to be good for mites and it is natural I think, not toxic.

I am not a mites expert but I try to learn about them. I've found these links useful:

A few notes:

Flat mites (False spider mites):

-They are larger than tarsonemid mites, but they are smaller than the well known spider mite (red spider mite, Tetranychus).
-Flat mites genus on orchids : Brevipalpus, Tenuipalpus (Phalaenopsis mite).
-A lot of information is available about flat mites on orchids.
-No web.
-Don’t move quickly.
-Botanigard if effective against the species I’ve found in my collection.
-Some auxilliaries can eat them (I introduced Neoseiulus cucumeris and Amblyseius swirski and found fast moving mites thought the flat mites colonies on my Masds. Sorry, unable to know if it was cucumeris or swirski!).

Tarsonemid mites (Thread-footed mites) :

-Cyclamen mites and Broad mites. Also Bulb scale mites, but not of concern on orchids.
-I’ve found difficult to find accurate informations about Tarsonemid mites on orchids.
-Magnification: 20 X to 40 X
