1. Wheat pest calendar Mary Burrows, David Weaver, Fabian Menalled

2. Objective To develop a wheat pest calendar to assist producers, county agents, and crop consultants to identify and manage common wheat disease, insect, and weed pests.

7. Results 2000 copies printed Lots of positive feedback PDF is available on Extn Plant Path website http://www.msuextension.org/plantpath/ Next year: Pulse pest calendar funded by NPGA Any future interest in barley calendar, or other crop or theme?

8. Wheat virus variety trials and on-farm fungicide demonstration trials Mary Burrows, Luther Talbert, Tom Blake, Alan Dyer, Phil Bruckner, Dan Picard, Joe Broesder, Jesse Fulbright, Gregg Carlson

9. Objectives 1. Evaluate widely planted winter wheat, spring wheat and barley varieties in Montana for susceptibility to Wheat streak mosaic virus and Triticum mosaic virus 2. Evaluate early-season fungicides in wheat in on- farm demonstration trials. 3. Disseminate the results of these studies to growers in Montana and throughout the Great Plains region.

10. Disease cycle of WSMV

11. Winter wheat

12. Winter wheat yield Avg yield loss = 6%

13. Average yield loss (%) due to WSMV, 2008-2010 *Hail damage Negative # means yield gain from WSMV

14. Spring wheat

15. The hope Later reality

16. WSMV-inoculated spring wheat plots were more severely damaged than the controls No inoculation WSMV-CI WSMV-HI Buffer

17. Spring wheat yields, 2010

18. Average yield loss (%) due to WSMV, 2008-2010

19. Objective 2. Evaluate early- season fungicides in wheat in on-farm demonstration trials.

20. Yield results

21. Additional data from NARC site VariableAverage Significant differences? Moisture 9.5%NS Test wt 61.4 lb/buNS Protein 13.2%NS Sawfly rating 9.78NS

22. Dissemination of this information Grant term: –Presentations: four in-state presentations (420 attendees); in June I was invited to Rapid City, SD to speak to the NCERA-184 Cereal Pathology group about wheat viruses. –Appearances on Montana Ag Live: three appearances (approximately 20,000 viewers per appearance) –AgAlerts: four agalerts related to viruses and fungicide use in cereals with 406 viewers. –Publications: M. Burrows, D. Weaver and M. Menalled. 2011. Common Montana Wheat Pests. Calendar. Burrows, M., M. Moffet, P. Bruckner, J. Berg, M. Johnston.

23. Plans for next year Continue WSMV variety trials On-farm demonstration trials for foliar fungicides on dryland winter wheat –Tillering stage applications –4 counties (Pondera, Toole, Liberty, Hill), –2 research stations (Conrad, Havre) –Fall applications at research stations: relationship to winterkill? –Spring applications all sites: ‘plant health benefit’ in absence of disease pressure Any other ideas?
