Introduction and Summary
The video “Identification and Control of Nematodes in Turfgrass and a Little Tall Fescue for Good Measure” presented by Dr. Jim Kerns provides a comprehensive overview of the challenges and management strategies for nematodes in turfgrass, with a focus on tall fescue. The key points covered in the video include:
- Nematode Biology and Management: The presentation covers the biology of nematodes, their prevalence, adaptability, and the challenges they pose to turfgrass. It discusses the shift from solely killing nematodes to more effective management strategies.
- Identification and Symptoms: The video explains how to identify nematode problems in turfgrass, focusing on field symptoms such as reduced growth, wilting, and deformed roots. It also discusses the variability of nematode populations and the importance of soil type.
- Chemical Control: The video highlights the use of chemical nematicides for managing nematode populations, noting the transition from older nematicides to newer, safer products. It recommends timing and application methods for these chemicals, emphasizing the need for immediate irrigation after application.
- Cultural Control: The presentation discusses cultural control methods, such as deep, infrequent watering, nitrogen fertility, increased mowing heights, and regular aeration, to help turfgrasses tolerate nematode feeding damage.
- Recent Research and Developments: The video touches on recent research, including studies on tall fescue varieties and their susceptibility to certain nematodes, as well as the potential of using tall fescue as a preplant cover crop to reduce the need for chemical nematicides.
Conclusion
The video provides a comprehensive and informative overview of nematode identification, management, and control in turfgrass, with a particular focus on tall fescue. The presentation covers a range of strategies, from chemical to cultural control methods, and highlights the importance of understanding nematode biology for effective turfgrass care.
