Updated Recommendations for Nematodes in Corn - UNL CropWatch, June 21, 2013
June 21, 2013
Plant parasitic nematodes of corn occur in every field to some extent. Historically, sampling techniques and management recommendations have largely relied on limited research data and observations that do not always reflect current production practices and our improved understanding of nematode behavior.

Recently, a team of nematologists and plant pathologists from across the Midwest worked together to revise and update recommendations related to nematode sampling, interpreting the results of nematode analyses and management recommendations.
Dr. Greg Tylka, Iowa State University summarized those revised recommendations and related discussions in an ISU Integrated Crop Management newsletter article, New Approach to Assessing Possible Nematode Damage to Corn.
Several laboratories in the Midwest can analyze soil and plant material for plant parasitic nematodes. Samples can be submitted to the UNL Plant and Pest Diagnostic Clinic for analysis using the same guidelines summarized in Tylka's article. The address and sample submission form are available online on the PPDC website.
