Chlorosis from Spider mite damage or Virus?

    Hello all,

    I just had a Dendrobium Nobile get badly attacked by spider mites.

    I can’t speak to which kind of spider mite other than the fact that they do spin webs as webs were present between the leaves. I thought I saw red dots moving along with white ones. I am going to be using azamax and avid to get rid of them.

    My concern now however is that some of the leaves are showing chlorosis. This worries me because I know that spider mites can transmit viruses.

    Is this spotting (pics 1, 2, 6, 7) likely a virus? It kind of looks vaguely like CymMV. Can web spinning mites transmit that? Is it just the result of severe mite damage?

    The underside of some of the leaves (pics 3, 4) is very silvery meaning it is a bad infestation and those leaves were severely damaged. Would this also be the cause of the other chlorosis?

    Thank you.

    It doesn't look like a virus to me. You might isolate the plant and wait to see if more classic symptoms appear later.
