Not all Corn Nematodes are the Same

While soybean cyst nematodes have been getting most of the fanfare the past few years, corn nematodes are making their debut. While all can be damaging, some are a bit nastier than others. Their is a wide range of acceptable thresholds to treatment among the various species. The chart below gives a range of damage thresholds from several universities. While the numbers vary between sources, the pattern of the more damaging nematodes is constant. Needle and sting nematodes have the greatest potential for damage if detected.

We can analyze soil for all of these species in our N3 soil test package that provides a count for each species of nematodes with damage interpretations. For more information on sampling or sample submission contact your ALGL agronomy representative.
