    Default Help with spots on Phal

    Suddenly today I noticed these two light-colored spots on a phal leave. There are no trails of "sticky stuff" to indicate snails, no actual evidence of a chewing cridder...but the circle with the bull's eye is bothersome to me as it may indicate some other insect or bacterial something. I try to keep a clean house (GH) and use RD-20 on a regular basis...so should I be concerned or it's nothing and I'm over-reacting? Comments, please

    I had some response that mosquitoes, the male, can do this. Any comments???? I know I don't have thrips...so far! And I can't believe fungus gnats are eating leaves, since they usually reside in the moist growing media.

    Doc, check the underside of the leaves. Use a white paper towel - a bit damp and wipe the underside of the leaf. Do you see any red color on the papertowel? If so, you may have spider-mites. They are hard to see, but will appear red-orange on a paper towel. If you do, you will need to spray again, wait four days and then spray a second time.

    Cheers,
    BD
