    I have 2 customers having problems with their shrubs, getting alot of brown spots on leaves and it looks like ****. Any ideas on what this could be? Please advise ASAP.

    I agree with Chuck but you'll need to determine wheather it's caused by a bacteria or fungus.

    Ligustrum.......? If so, to much water. Will go away as soon as a new flush of growth comes and old leaves drop. Can you correct the water problem? with regards... devildog

    it appears to be leaf spot from looking at it. if you go to
    www.hort.uconn.edu and click on the IPM section, they have a writeup on leaf spot. it sounds and looks like what you have, but it could be something different as well.

    It appears to be a form of insect damage. Although I can see where a blight of some kind appears to be a secondary cause.
    Dependent upon temps, a brief warm up will release certain species of aphids which cause a pattern of injury seen here then the disease pathogen takes over.
    I would:
    #1 check for insect infestation on both the plants and in the soil
    #2 check for disease through a analytical report from a reputable testing facility in your area.

    Are that photo from yesterday, or last summer? Broadleaf evergreen, then? What have temps been if current pic? What side of structure (E,W,N,S) are plants on?
