One of the keys to achieving maximum economic returns is minimizing disease pressure, and the cornerstone of effective disease management is accurate diagnosis. This is not easy given the broad spectrum of diseases found in the field—and also given that symptoms can look very similar.
A Farmer’s Guide to Corn Diseases provides the images, tools, and non-technical guidance to help ag professionals accurately diagnose corn diseases and disorders found in the fields of the United States, Canada, and other countries where corn is grown.
This no-nonsense, highly accessible book features diagnostic keys and other extensive cross-referencing tools to help users quickly find diseases and minimize identification errors. It features…
•    An easy-to-follow introduction to corn diseases and disorders
•    A non-technical overview on diagnosing corn diseases in a field setting
•    Disease listings organized by part of the corn plant affected
•    Disease distribution maps to help narrow the search for suspect diseases
•    Basic instructions for using diagnostic and scouting tools, like hand lenses
•    A glossary defining the various diseases and diagnostic terms used in the book
A Farmer’s Guide to Corn Diseases also provides general management recommendations, giving growers and crop specialists an excellent primer for discussions with extension or crop specialists in their specific state or province about localized treatments.
This book is a truly collaborative effort. Thirty-three experts from more than 20 universities, agencies, and companies packed their vast collective corn disease knowledge into this highly accessible book written with the grower in mind.
