Color my world: Use of turf colorants | Grady Miller, Ph.D., North Carolina State University
2026-06-08 13:00 - 14:00 (America/Halifax)
Dr. Grady Miller from North Carolina State University presents a comprehensive educational discussion on turf grass colorants for golf course management.
The presentation covers the fundamentals of when and where to use colorants as alternatives to overseeding, particularly for winter color on dormant warm-season grasses like Bermuda and Zoysia. Miller explains the differences between pigments and colorants, their application rates, longevity, and cost considerations. He discusses various application methods from large boom sprayers to hand wands, and shares research findings on color retention, effects on photosynthesis, and potential issues like product transfer onto uniforms.
The webinar includes practical examples from golf courses, combination approaches with overseeding at reduced rates, and innovative uses like colored sand for topdressing. Miller emphasizes that while these products offer cost-effective alternatives to overseeding with benefits like no spring competition issues, they also have limitations such as shorter color duration and lack of the glossy appearance of live grass.

Surprising surfactants! Key insights from six years of turfgrass research
2026-07-16 13:00 - 14:00 (America/Halifax)
In this TurfNet University webinar sponsored by LebanonTurf, John Dempsey, Ph.D., unpack sthe real value of surfactants, wetting agents, and penetrants in modern turf management. Moving beyond their reputation as simple water movers, this session examines what these products do in the rootzone—and whether they truly deliver a worthwhile return on investment.
Drawing on six years of rigorous turfgrass research, including recently published peer-reviewed studies, the webinar:

Demonstrates how surfactants can significantly improve turf health and quality—even under periods of regular rainfall
Explains how different surfactant chemistries, including the latest nanoparticle-based formulations, influence rootzone moisture dynamics
Highlights measurable impacts on turf performance, from plant health and visual quality to consistency and surface playability
Provides guidance on practical use patterns and decision-making to maximize benefits and justify costs

You’ll come away with a clearer, research-based understanding of how to select and use surfactants to enhance turf performance across golf courses, sports fields, and high-performance lawns.

Turning turf trials into real-world results – A practical guide to turfgrass research and data analysis
2026-11-19 13:00 - 14:00 (America/New_York)
In this TurfNet University webinar presented by LebanonTurf, John Dempsey, Ph.D., walks attendees step-by-step through the research process for turfgrass and golf course management — from planning and applying treatments to collecting data, analysing results, and clearly presenting your findings. Using real-world examples from turf trials, he will discuss how to design simple, practical research on your own course, apply and compare treatments such as products, cultivars, and irrigation strategies, and collect reliable data on turf quality, pests, water use, soil health, and playability.
Attendees will learn simple statistical techniques to interpret results, and how to present clear, confident findings.
This session is ideal for greenkeepers, course managers, agronomists and anyone who wants to turn trial and error into evidence-based decision-making on the golf course.
