Summary

​This presentation will help consultants, growers, and other practitioners scout and manage the root lesion nematode—the most common nematode pest in most potato fields. This presentation will explain when to be concerned about the root lesion nematode, the interaction of this nematode and Verticillium dahliae for potato early dying disease, and the options available to maintain population densities below damaging levels. The life cycle of the root lesion nematode will be covered, including this pest’s remarkable ability to persist without feeding. By the end of this presentation, practitioners should know more about the root lesion nematode life cycle, be aware of their patchy distribution in the field, understand the importance of managing nematodes throughout the entire rotation, and have a general knowledge of the tools available to do so.
