August 2011. Spots on eggplant fruits sent from South Vietnam, said to be Solanum macrocarpon, African eggplant. They developed during the rainy season.
[Editor] One suggestion was Alternaria blight, managed by applying copper or Indofil z-78. This is a product that contains zineb. As such, it is adviable to consider carefully the use of this product in light of restrictions in the USA and Europe. See, for instance, www.pan-europe.info/Archive/Banned%20and%20authorised.htm#banned, or the PANS Pesticides Database www.pesticideinfo.org/Detail_Chemical.jsp
However, the images do not show typical symptoms of Alternaria. There are many references to this fungus and the damage it causes on the Internet, e.g., Alabama Extension System: www.aces.edu/pubs/docs/A/ANR-1098/. The lesions on both the leaves and fruit show a concentratric ring pattern which is absent from the pictures above.
Another possibility is that the damage is caused by loopers or armyworms, followed by fungal and/or bacterial infection resulting in the lesions shown in the photos. The markings on the leaf (second row, right) are more likely to be caused by the rasping of a caterpillar then a fungal infection.
