Question
Hi Jim

Can you recommend a pictorial book or guide for identifying diseases of forest trees, including root, leaf, and stem and branch diseases?  The book should also indicate the pathogens, fungi, vectors, etc. causing the disease, as well as all treatments; biological, chemical, genetic, etc.--a complete guide that a forester would use in the field.

I am most interested in western evergreen forests, but a U.S.-wide book that includes broadleafs will be fine too.

Thanks much!

Pete

Answer
There are several books on ID of diseases The best is from Comstock-- Diseases or Trees and shrubs. It will allow the ID of the disease and then the best controls or treatments can be Goggled for that disease. http://www.cornellpress.cornell.edu/book/?GCOI=80140100028970
