The Root Lesion nematode, Pratylenchus spp., is very common in the north central United States, ranking first or second for incidence among pest nematodes in Illinois (Mekete et al., 2011), Iowa (Tylka et al. 2011), and Minnesota(Chen et al., 2012). It is the most common pest nematode recovered from samples sent to the UW Nematode Diagnostic Service in Wisconsin. The percentage of samples positive for Root Lesion ranged from 90 to 95% for 2013 to 2016 and represented the majority of the counties with corn and soybean production.
