Grape diseases

"This is a practical book on grape diseases aimed at vine-growers and students who are looking for a summary of each vine disease. It describes the symptoms, diseases cycle, development and predisposing conditions of each disease, and the methods of controlling it. Tables are included at the end of the book to enable diseases to be identified form the various parts of the vine, i. e. leaves, shoots, trunks, inflorescences, grapes and roots . The 200 colour photographs found separate Jrom the text, and the 80 photographs and figures within the text, willfacilitate diseases identification in the vineyard. Treatment products are given according to chemical origin but I have also included, in brackets, the names of leading commercial products. My aim is not to advertise any particular product, but to enable readers to find their way around the complicated advertising names that often change each year and are therefore difficult to follow. In fact, some substances have ouly a short life span because resistance to the fungicide develops. This comp licates the use of these products and means that trea tmen ts con tain ing differen t che - mical groups must be alternated and those chemicals that have become completely ineffective no longer used. I should like to give my sincere thanks to Mr Arnould, Director of "Revue cles Œnologues" and "OENO PLURIMEDIA" for publishing this book in English. I should also like to thank Jaqueline Smith who has taken on the task of translating it." Pierre GALET
