    I beleive these are "burning bushes"- I forget the proper name. Any way, any idea what the problem is?

    Check for white lumps about the size of a flea.....if you see them probably scale. Will be on leaves and stems.

    I would agree that scale is probably at work here... I doubt you will find any on the leaves, but they are white, and generally found in masses on the stems.

    Now, if the leaves were gone from the top and not the bottom, I'd have to say spider mites. But they're not, so it's probably typical euonymous (never have been able to spell that d*mn name right...) scale.

    Euonymus alatus compacta (Burning Bush) is resistant to the normal white scale.

    Insect damage is normally sporatic not uniform such as in the first photo
    Has anyone sprayed in the direct area?
    The damage appears to be from phototoxcity,(or pesticide damage)

    It could be from herbicide damage, I'll give you that. But I will disagree on the original statement about E. alatus compacta being resistant. I've seen it too much for them to be resistant! Depending on the numbers of scale involved, it could be a very uniform appearance like is shown....

    D.Felix:
    You mentioned the white scale,This plant is resistant
    to common white-colored "Euonymus scale"

    I should have finished the statement
    It is not resistant to:

    Winged Euonymus scale is a significant pest problem when it occurs, sucking the sap from the stems and branches and leading to a signficant decline or slow death of the shrub; this pest is brown- to gray-colored and is a different species of scale as compared to the white-colored "Euonymus scale"
