Managing Vineyard Diseases

(book excerpts)

Disease management is an important and integral part of wine grape production. Grapevine diseases are caused by microscopic organisms referred to as plant pathogens. There are several categories of these organisms that may be damaging to plants such as fungi, bacteria, and viruses. Vineyard disease management practices rely on anticipating occurrence of disease and attacking vulnerable points in the disease cycle (i.e., weak links in the infection chain). Therefore, correct diagnosis of a disease is necessary to identify the pathogen, which is the real target of any disease management program. A thorough understanding of the disease cycle, including climatic and other environmental factors that influence the cycle, and cultural requirements of the host plant, are essential to effective management of any disease.
