Compendium of Wheat Diseases and Pests, Third Edition is the definitive publication on diseases of wheat, completely updated since the previous edition published in 1987. Twenty years of advances and new discoveries about wheat diseases are delivered in this new edition, making it the largest compendium ever in the series.  

More than 70 contributing plant pathologists and entomologists, all experts in their fields, have contributed to this authoritative compendium. A new section on major insect and mite pests of wheat has been added to make this a truly comprehensive reference. This new third edition is re-designed to be easier to use than ever before. It incorporates 50% more images integrated with the corresponding descriptions of disease symptoms, causes, life cycles, and control practices.

Compendium of Wheat Diseases and Pests, Third Edition is a must-have resource for anyone responsible for helping to ensure a healthy, productive wheat crop, including growers, crop consultants, and agricultural scientists from every discipline.

What’s New in the Third Edition?

• 32 new chapters – all other chapters are up-to-date
• A major section on insects and mites covers 16 of the most important to control
• 88 more images than the previous edition – nearly all images are new!
• 90% of the images are in color
• 70 authors writing chapters in their expertise area

Wheat is one of the most important grain crops in the United States and Canada and is grown as both a staple food crop and an export crop. Approximately 50% of the grain produced in the United States is exported. To reap the greatest economic returns, farmers must keep their wheat crops as healthy as possible. But given the many diseases that exist in wheat production, farmers may struggle to diagnose and manage diseases of importance.

With easy-to-use keys and cross-referencing tools that enhance efficient diagnosis, A Farmer’s Guide to Wheat Diseases helps growers pinpoint diseases and disorders in the field. The management recommendations it offers are intentionally general and meant to give growers and crop specialists a starting place to discuss more localized treatment recommendations with Extension or crop specialists in their region.

This highly accessible guide has these features:

• An easy-to-follow introduction to wheat diseases and disorders

• A nontechnical overview on diagnosing wheat diseases in a field setting

• Disease descriptions organized by part of the wheat plant affected

• Disease distribution maps to help narrow the search for suspect diseases

• Basic instructions for using diagnostic and scouting tools, such as hand lenses

• A glossary defining the various diseases and diagnostic terms used in the book

A collaborative effort, this book compiles the knowledge and expertise of 43 contributors from more than 25 universities and agencies. The result is the first comprehensive overview of wheat diseases across the United States and Canada written and priced for farmers.

This is the third book in the successful Farmer’s Guide series, which also includes A Farmer’s Guide to Corn Diseases and A Farmer’s Guide to Soybean Diseases.
