Compendium of Sweetpotato Diseases, Pests, and Disorders, Second Edition arrives as sweetpotato production is increasing dramatically in the United States, expanding to states that have not traditionally produced the crop, and as sweetpotato is being adopted as a critical source of vitamin A in many countries around the world. Nearly 50% longer than the previous edition, this is the most comprehensive book ever published describing the many diseases, insect pests, nutrient disorders, herbicide damage, and other disorders affecting the world's seventh most important food crop.
The second edition contains 325 color photographs (an increase of 243 compared with the previous edition) depicting the diagnostic symptoms of these diseases and disorders. These features make Compendium of Sweetpotato Diseases, Pests, and Disorders invaluable to growers, extension specialists, and diagnosticians in their efforts to accurately identify diseases and disorders they find on sweetpotatoes and to develop strategies to manage these problems.
Compendium of Sweetpotato Diseases, Pests, and Disorders provides the most up-to-date and authoritative information available on each disease prepared by leading experts in each discipline.Each section has a comprehensive list of the critical research publications that will allow researchers to quickly dive into work on diseases that may be new to them.
The insect section is completely new. The virus section has been entirely rewritten to reflect the vast progress made in the last 25 years in understanding sweetpotato virus diseases. The nutrient disorder and herbicide injury sections have been completely rewritten and illustrated using photographs of symptoms produced under carefully controlled conditions to assure complete accuracy. The nematode section has been co mpletely rewritten and every section provides the most recent information available.
