Anyone know a sure-fire way to tell if your indoor plant has mosaic virus? I have an orchid and it has signs-yellowing blotchy leaves, little black spots underneath that are indented...some are yellowing at the edges of the it spots or is it more random blotchy amoeba-like shapes? I've heard some orchids just naturally ahve black spots on the leaves, but I think those are more pin-prick size than freckle size or larger.
If it IS mosaic virus, should i just toss the plant [tears] or is there something I can use to get rid of the virus?

Here's the info on Virus.

Many virus diseases infect Orchids but diagnosis can be difficult; virus symptoms often resembles less serious problems.

Black, red or yellow spots or steaks appear on leaves. Flowers may have white or brown streaks or mosaic patterns.

Have plant tested to confirm diagnosis. Plant viruses are incurable; destroy infected plants. Plants may carry visruses without showing symptoms, so always sterilize tools before use on each plant.

Check also "leaf spot" fungus such as Cercospora or Colletotrichum.

Leaves have sunken, purplish brown or black spots. Spots start as yellow areas on leaf undersides, becoming more visible on both sides of leaf as they darken.

Take plant outdoors and spray with a fungicide containing benomyl. Remove badly damaged leaves. Leaves with a few spots may be left on plant. It is a rare orchid that doesn't have a spot or two.

Thanks for the info! When is it "safe" to bring the orchid back in after spraying?
