Hello,
This past January I recieved a shipment from oakhill containing a bunch of plants, one being a Blc Emerald Isle. This plant had some brownish spots, maybe insect damage. I let it go, thinking that it was taken care of by oakhill.

Tis last week, I noticed that the same plant as well as a paph and a dend have all started getting wierd makings on them.. The Blc got very minute siverish dots on a leaf and the brownish markings spread to another leaf :ohmy: . The dend is getting spots on new and old growth where their is no chlorophyll and is transparent :ohmy: . I cannot detect scale nor mealybugs so i think it may be spider mites or phal mites. I never hasd these before and i dont know what to look for and how to tell the difference. I did spray all of the plants with a spray containing neem oil on top and below th leaves. Any ideas of the problem? :cry:

Could very well be spider mites. Do you see any webbing? Do you have a magnifying glass that you can inspect the underside of the leaves with? Mites are tiny.

i did inspect the leaves...no webbing or mites. Maybe i am just paranoid about little marks..i dont know...maybe false spider mites?

Ryan

depending on the mite, they can be VERY small. some, strong magnification is required to see them, though their damage is easier to see.
can you post a photo?

I'm not an expert, but that doesn't look like spider mite damage to me. More like a fungal or bacterial problem. Do you have good airflow around your plants?

This looks like microfungus damage. It is more common in phalaenopsis but oncidiums and cattleyas can also become infected. It is extremely difficult to treat. It might be best to discard any infected plants and routinely spray plants that don't show any of these symptoms with a fungicide such as funginex.

Ryan, It does look like possible mite damage but needed a little more magnification and shaper focus to be sure. Doesn't look like microfungus to me. If the Neem doeen't slow it down try a good miticide such as Tetrasan. I would isolate the affected plants as much as possible.

Thanks for the all the help...

yes i do keep the plants where there is good airflow. I will continue with the neem oil treatment

thanks
