Plant Disease Management Handbook
Unlike the Insect Management Handbook, this book is organized alphabetically by common
name of the host plant. Also, registered chemicals are not always divided into separate Home
and Commercial sections, although in some cases they are. In either case, an “H” is used to
identify products available for use by homeowners.
Book version: Table of Contents is on page 1-iii (2014 version). Section 4 has an alphabetical
listing of host plants by common name. Within each host plant, diseases are listed alphabetically.
Online version: Click on “Hosts and their diseases”, then enter the name of the host plant in the
search box and click “apply”. A list of diseases of that host will appear, listed alphabetically.
