A key to achieving maximum economic returns is minimizing disease pressure, and the foundation 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 Soybean Diseases provides the images, tools, and non-technical guidance to help ag professionals accurately diagnose soybean diseases and disorders found in the fields of the United States, Canada, and other countries where soybean 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 soybean diseases and disorders

• A non-technical overview on diagnosing soybean diseases in a field setting

• Disease listings organized by part of the soybean 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 Soybean 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-five experts from more than 20 universities, agencies, and companies packed their vast collective soybean disease knowledge into this highly accessible book written with the grower in mind.
