Battle Botrytis! All about pathogen biology and management options
Presented by Dr. Luisa Santamaria, nursery pathology specialist at Oregon State University

Botrytis cinerea, also known as gray mold, is one of the most devastating pathogens in greenhouse ornamentals production. This presentation will cover different aspects related to the pathogen and the disease such as its biology, epidemiology, and the best management practices for commonly affected ornamental crops. You will come away with a better understanding of how to prevent and mitigate this disease using integrated pest management, with an emphasis on cultural control mechanisms for greenhouse and outdoor nursery environments. In addition to cultural management strategies, you'll learn about the most effective chemicals and biorational products and how to apply them safely.

Dr. Luisa Santamaria, associate professor and extension plant pathologist at Oregon State University, works from the North Willamette Research and Extension Center (NWREC) in Aurora, Oregon. Her responsibilities include extension and outreach activities to support the nursery and greenhouse industry in Oregon, and applied research to manage plant diseases in nursery crops. Her bilingual education program supports different agricultural commodities to promote the production of healthy plants and worker awareness about good agricultural practices. Her current applied research is on soil-borne pathogens in ornamentals.

Calibration and water volume for efficient chemical applications
Presented by Tim and Dan Schaal of Airtec Sprayers, Inc. 

Proper calibration of application equipment is the key to efficiently and safely managing pests and disease on crops. Misapplication of chemicals is both dangerous and costly, but keeping up with the latest technology and techniques can be challenging for busy growers and landscape maintenance crews. Tim and Dan Schaal of Airtec Sprayers will dive into several sprayer options and explain how to calibrate them for different chemical applications. This session will help growers choose the right sprayers for their operations, minimize drift/runoff, and avoid harmful chemical misapplication.

Airtec Sprayers is a multigenerational family-owned business, started by Dale Schaal in 1992. Dale developed technology that would help growers target their chemical spray applications with minimal drift. Through trial and error and using his farming experience, Dale developed several revolutionary sprayers, which are now used by farmers across the US, Latin America and Canada. Today, Dale serves as President of Airtec Sprayers, Inc. while his two sons, Timothy Schaal (CEO) and Daniel Schaal (VP of Sales), manage the day to day operations of the business.

Thursday, November 12 | 9:45am-11:15am
Crop-adapted spraying (CAS) in nursery production
Presented by Brian Hill, nursery crops faculty research assistant at Oregon State University

What is crop adaptive spraying, and how can you use it to improve the safety and efficacy of your pest management program? This session shares the history of CAS and provides insight into the latest research on its application potential for nursery crops. Brian Hill will discuss which crops are best suited for CAS and demonstrate how to calibrate sprayers for efficacy on specific crops based on their planting arrangement, cultivar, maturity and crop stage/season. He will also explain how CAS can be implemented in your integrated pest management (IPM) program, eliminating excessive chemical application and reducing damage to non-target insect and plant species. The talk will provide a step-by-step method of adjusting sensor-based sprayer application rates while maintaining efficacy. While there is always an adjustment period for specific application, these steps will shorten the learning curve by providing a proven jumping-off point.

Brian Hill is a soil scientist who joined the NWREC nursery team in the spring of 2019. He is a recent graduate with a B.S in crop and soil science and a M.S. in soil physics. He is currently applying his modeling skills and passion for sustainable practices of IPM to the North Willamette nursery industry through experimentation. He built the NWREC Substrate Lab where soil and soilless media can be evaluated, yielding a spectrum of physical properties. He is also leading the North Willamette Intelligent Spray Program, where laser-guided air blast sprayers are evaluated for efficiency, pesticide savings and environmental impact reduction.


Registrations cancelled on or before November 6, 2020, will receive a full refund. No refunds will be given after November 6, 2020.
