Excerpt from Insecticides, Fungicides and Weedkillers: A Practical Manual on the Diseases of Plants and Their Remedies, for the Use of Manufacturing Chemists, Agriculturists, Arboriculturists and Horticulturists So as to render this treatise complete in itself it was deemed necessary to pass in review the numerous experiments made up to now to suppress and prevent plant diseases. The author has striven from the aggregate of the results reported to frame certain scientific rules which appear to deter mine the success of certain classical methods and to explain certain notorious failures, rules which may serve as a useful guide to future experiment and aid in the discovery of new pro ducts of greater efficiency than those now at our disposal. The preventive and combative treatment of the diseases of plants requires a profound knowledge of the parasite as well as the product used as a remedy. Success depends on the judicious choice of the remedy utilized and the manner in which it is applied. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
