Brief Summary of Minutes of Annual Meeting

The meeting was held at the Hilton Pensacola Beach in Pensacola, Florida on February 28th, 2023and opened at 8:00am. The discussion started with participant introductions and individual state reports from Mississippi, Ontario, Iowa, Ohio, Oklahoma, North Dakota, South Dakota, Wisconsin, New York, Pennsylvania, South Dakota, Nebraska, Minnesota, Delaware/Maryland, Kansas, Louisiana, Indiana, Kentucky, Tennessee, and Arkansas. There was an open group discussion about the complex of viruses that contribute to wheat streak mosaic virus. Kelsey Andersen Onofre mentioned a regional meeting scheduled to be held in Texas in April 2023. The group discussed the fungicide efficacy table and the addition of Prosaro Pro to the efficacy table for 2023. Kiersten Wise gave an update about the Crop Protection Network, including metrics about site visits and impact. The group had a productive 2022, launching a new website and new initiatives, including on-demand webinars through CPN TV. Andrew Friskop presented about the wheat disease loss estimates, which are compiled through members of NCERA-184 annually. The most economically important diseases from 2018-2021 were Fusarium head blight, stripe rust, leaf rust, bacterial leaf streak, and tan spot. The NCERA-184 organized a uniform fungicide trial with the 2022 treatment list including 9 treatments focused on the FGS8-9 timing, with one treatment at a 10.5.1 timing, and a non-treated control. Meriem Aoun presented on rust resistance in US hard red winter wheat regional nurseries. Wanderson Moraes presented recent research evaluating the influence of environmental factors on zearalenone (ZEA) accumulation in wheat. Europe has set thresholds for ZEA at .1 ppm, indicating that it is more toxic than DON. A main recommendation was that early harvest can help mitigate ZEA accumulation. Emmanuel Byamukama gave an update on USDA-NIFA initiatives. Martin Chilvers presented results from a meta-analysis of yield responses to fungicides at three different timings in winter wheat (Fk 4-6, Fk 9, 10.5.1). This work found an unexpected 4 bu/A yield response from the early application. It was suggested that multi-state work could help understand yield benefits of early applications. Erick De Wolf presented an update about research evaluating stripe rust heat tolerance, with new evidence that contemporary isolates are better adapted to warm conditions than previously believed. This points to either pathogen evolution or the introduction of novel populations of the stripe rust pathogen in the Great Plains. Joe LaForest presented updates about agpestmonitor and discussed future plans for wheat within this platform. Tyler McFeaters presented updates from Pennsylvania small grains fungicide trials. His group has been working to compile 20 years of PDMR data and develop meta-analyses across different diseases. Oluseyi Fajolu presented an updated from the USDA-ARS cereal disease laboratory and discussed with the group the history of the survey and tips for sampling and sending samples to the CDL. She reminded attendees to sign up for the email listserv. Kelsey Andersen Onofre opened the business meeting and asked for an approval of the minutes. Erick DeWolf motioned to approve and Tom Allen seconded that. The 2022 minutes were approved. Venues were discussed for the 2023 meeting. The group agreed that a poll would be sent out after the meeting to finalize. Ken Obasa will take over as chair in 2023-2024. Erick DeWolf was nominated and elected as incoming chair to serve 2024-25. The meeting adjourned at 3:55pm.

Short-term Outcomes:  Fungicide efficacy trials were conducted in multiple states and locations, with several states participatingin a coordiated uniform fungicide trial. Key diseases were monitored across the US throughout the growing season. Members from participating states published more than 25 peer reviewed research articles and more than 90 extension publications in 2021. In total, efforts are advancing best managment practices for wheat disaeses in the US. 

Outputs: Members from participating states shared information through winter meetings, publications, extension publications, radio, television, YouTube, and social media. Members worked together to produce the following outputs: 

• The 2022 Fungicide Efficacy for Control of Wheat Diseases publication (CPN-3002-W) https://cropprotectionnetwork.s3.amazonaws.com/cpn3002_fungicideefficacywheatdisease_final.pdf
• Updates to the Fusarium Head Blight forecasting tool http://www.wheatscab.psu.edu/
• 2022 Wheat Disease Loss Estimates from the United States and Ontario, Canada (https://cropprotectionnetwork.org/publications/wheat-disease-loss-estimates-from-the-united-states-and-ontario-canada-2022)

Activities: NCERA-184 works under three primary objectives:

• Objective 1. Better characterize best management practices for Fusarium head blight and leaf diseases in wheat and barley
  • The group continues to examine the roles of environment, variety, and chemical applications on management of important emerging or reemerging diseases in wheat and barley through state-level field trials. Results are reported through publications and extension reports by each state. These efforts contribute to the development of new wheat varieites across market classes. 
• Objective 2. Conduct fungicide efficacy trials for diseases in small grains
  • Current research in participating states has focused on both fungicide efficacy and the integration of variety resistance and well-timed fungicides for the control of Fusarium head blight. This research is part of the multi-state Integrated Management Coordinated Project funded through the U.S. Wheat and Barley Scab Initiative. Results have indicated the importance of using multiple management strategies to reduce FHB severity and grain DON levels. Research has also indicated that newer fungicides such as Miravis Ace,Sphaerex, and Prosaro Pro are effective. In addition, the project has initiated a uniform fungicide trial protocol for diseases other than Fusarium head blight. The 2021-2022 season was the first year of this protocol. Results were summarized by Andrew Friskop and presented at the annual meeting in 2023. 
• Objective 3. Improve disease management through forecasting tools
  • The NCERA-184 Committee coordinates a national level forecasting effort for FHB in wheat. The forecasting system is supported by the USDA USWBSI and provides daily estimates of disease risk.  A stripe rust forecasting model is currently being validated in Kansas and surrounding states, with the goal of a future national scale forecasting system. These efforts for forecasting for stripe rust and other foliar diseases of wheat are supported through the USDA National Predictive Model Tool Initiative (NPMTI).  
• Objective 4. Monitor and report regional disease distributions and impact
  Comments: Rust diseases reported through platforms such as the ipmPIPE and the Cereal Disease Lab Rust Bulletin as well as disease loss estimates.
  • Wheat and barley disease occurance were reported by individual states through state-level and regional reporting outlets. Cereal rusts were reported to the cereal disease lab and published in the Cereal Disease Lab Rust Bulletin. Loss estimates were compiled by members of the NCERA-184 and published on the crop protection network (CPN) website.  

Milestones: In year 1 of 5 of this project (2021-2022), data were generated by partner states to compile national recommendations for fungicide efficacy and other best managemnt practices for small grain diseases.
