Dr. Lloyd Nackley, a plant ecologist, applies a systems approach to improve nursery and greenhouse management. With over 20 years of horticulture experience, including landscape design, ecological restoration, plant propagation, and nursery and greenhouse management, he is interested in understanding how natural and controlled environments impact plant growth and development, and how these interactions influence management decisions and societies' ability to sustain essential ecosystem goods and services. This was highlighted in his research on how climate change might affect horticultural crops, biofuel crops, and invasive plant species. His research helped reframe our ideas of invasive plant management.

Dr. Nackley's research program focuses on addressing four major challenges facing nursery and greenhouse production in Oregon: irrigation application, pest management, plant nutrition, and climate adaptation. His work supports production systems by providing practical solutions to enhance the efficiency of given resources and improve the sustainability of ecosystem goods and services. Highlights include integrating laser-guided spray systems, environmental sensing like load-cell based irrigation, and applying plant hydraulic frameworks to nursery production.

(2024) Managing Powdery Mildew in Greenhouse Tomato in Western Oregon In the Pacific Northwest, tomatoes crucial for farm income face powdery mildew threats. Farmers combat with fungicides, posing challenges for organics. UV-C light offers promise in high tunnels, but research is needed for optimization and minimal impact on plant growth.
(2023) Pesticide Redistribution and Its Implications on Pesticide Efficacy Pesticides that penetrate plant tissues or move to other parts of the plant may be more effective than pesticides that do not redistribute. Factor this property into your pesticide choice.
(2022) Nursery IPM Extension Program The Nursery IPM Extension program based at the North Willamette Research and Extension Center assists nursery and greenhouse growers to make informed decisions in all aspects of integrated pest management (IPM) including pest identification, monitoring, pest biology, thresholds, and pest management tactics.
(2021) How to Do Regular Maintenance on Air Blast Sprayers to Ensure Proper Care for Specialty Crops Air blast sprayers are one of the most common sprayer types used in specialty crop production. These machines are designed for heavy use on farms, and like all machinery, require regular attention to function effectively. This publication highlights periodic maintenance tasks for air blast sprayers. This is a general maintenance guide meant to complement the manual that comes with many sprayers.
(2020) Unmanned Aerial Systems: A guide for finding the right system for your Oregon farm Modern farm operations increasingly rely on technology to reduce workload and maximize farm profit. Unmanned aerial systems are another example of technology deployed for agricultural production. How can this technology save time and increase profits from agricultural operations in Oregon?
(2020) Hemp Sex-Ed Hemp cultivation in Oregon is expanding, but growers need to be aware of the problems associated with unwanted pollination. Find out why it's vital that farmers coordinate with their neighbors to ensure a healthy hemp crop.
(2019) Sensor Sprayers for Specialty Crop Production Sensor-controlled spray systems can help growers use fewer chemicals and less water while maintaining good pest control. Learn about the pros and cons of different types of sensor sprayers.
(2021) A Pocket Guide to Common Natural Enemies of Nursery Crops and Garden Pests in the Pacific Northwest Learn how to identify some common insects that prey on garden pests. See what they look like at various life stages, and learn how to encourage beneficial insects in your garden or nursery. Print this pocket guide on letter-size paper and cut pages as indicated to make a booklet.
