Second Edition of Soybean Cyst Nematode Field Guide Available

By Greg Tylka, Department of Plant Pathology and Microbiology

The soybean cyst nematode (SCN) is a major yield-limiting pathogen of soybeans in Iowa. The nematode was particularly damaging in the 2012 growing season because of the drought conditions. Thorough knowledge of SCN biology is the foundation for successful long-term management of the pest.

The Soybean Cyst Nematode Field Guide was first published and distributed by Iowa State University and the Iowa Soybean Association in 2008. The durable, pocket-sized book contains information about the biology of the nematode, as well as scouting methods, management strategies, disease interactions and the HG type test.
A revised, second edition of the Soybean Cyst Nematode Field Guide is now available. 

 

Updated and new information

Information and images throughout the publication have been updated in the second edition. Also, new information added to the second edition includes discussion of:

  • effects of drought on SCN biology and damage
  • development of SCN populations with increased reproduction on PI 88788 resistance
  • seed treatments as a management tool

 

Where to get copies

Individual copies of the second edition of the SCN Field Guide can be obtained at no charge from the Iowa Soybean Association by calling 800-383-1423. Copies also will be distributed to Iowa farmers at ISU Private Pesticide Applicator Training sessions this winter. Single copies of the revised field guide can be obtained at no charge from ISU Extension and Outreach field agronomists. The revised field guide is available for purchase from the ISU Extension Online Store (CSI 0012) and is available there as a downloadable PDF file
