Grape damage symptom and causal agent index

First Paragraph: These tables list only the prominent symptoms associated with known causes. Note that many of the symptoms will appear only at certain times of the year and not necessarily at the same time. Some symptoms, such as waterberry whose cause has not been confidently identified, have been omitted. For illustration and more detailed information, refer to U.C. Grape Pest Management Manual (U.C. publication #4015) and Grapevine Nutrition and Fertilization in the San Joaquin Valley (U.C. publication #4087).
