Compendium of Grape DiseasesThis compendium of diseases and disorders of grape was compiled as a reference for growers, viticulturists, crop advisers, and extension specialists as well as practicing plant pathologists. It was written for those with limited training in viticulture and pathology but has sufficient detail to be useful to students and professionals alike.Each section was written by an active researcher or recognized expert on the subject. Included among the more than 30 authors are some who have not previously published in the English language, thereby making their knowledge available for the first time to English readers.The structure and growth stages of the healthy grapevine are describe din the introduction in addition to a discussion of grapevine diversity that includes the important species of Vitis that have been used in breeding programs and as rootstocks. In subsequent sections, diseases are arranged according to causal agents. Diseases caused by biotic agents such as fungi, bacteria, viruses, and nematodes are presented in Part I. Diseases caused by fungi are further subdivided according to the major part of the plant affected. Part II covers some forms of mite and insect injury that could be confused with diseases. Disorders caused by abiotic factors, such as nutrient deficiencies, environmental stresses, and chemical toxicities, are the subject of Part III. Part IV discusses how cultural practices influence disease. Efforts to prevent disease spread in this clonally propagated crop through the selection of disease-free planting material are descried in Part V, including clonal selection, clean stock registration and certification, and quarantine. A list of equivalent disease names in French, German, Italian, and Spanish is presented in the Appendix. The glossary of both viticulture and plant pathological terms should aid all readers.Because of the international scope of this compendium, principles of disease control were purposely stressed rather than specific chemical control were purposely stressed rather than specific chemical control measures. Nevertheless, in sections where it seemed desirable, chemical control options are discussed in some detail. |
