Summary: This presentation will help consultants, growers, and other practioners scout and manage root lesion nematodes, the most common nematode pest in most potato fields. This presentation will explain when to be concerned about root lesion nematodes, the interaction of root lesion and Verticillium dahliae for the potato early dying disease, and the options available to maintain population densities of root lesion nematodes below damaging levels. The life cycle of root lesion nematodes will be covered including their remarkable ability to persist without feeding. By the end of this presentation, the practitioner 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.
