Nematodes Nematodes are a growing but often undetected pest problem in turfgrass throughout the United States, especially on low-mowed greens or other areas under stress. Nematodes often enhance root diseases confounding diagnosis and control. Nematode assays can help determine the type of nematode present and whether they are a concern. If current symptoms are validated with high nematode populations, curative applications of Indemnify should be made immediately. Consult your local area sales manager for specific timing and re-application interval. Re-applications will depend on the level of nematode populations/ damage. For courses where nematodes are not a major concern but wanting to be proactive with nematode management, apply Resilia TM root health solution at 4 fl. oz. per 1,000 sq. ft. A total of four applications can be made per year. For courses with a documented history of nematode damage, consider the following:
