Presentation Transcript

  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.

  3. 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?

  4. 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

  5. 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.

  6. Disease cycle of WSMV

  7. Winter wheat

  8. Winter wheat yield Avg yield loss = 6%

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

  10. Spring wheat

  11. The hope Later reality

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

  13. Spring wheat yields, 2010

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

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

  16. Yield results

  17. Additional data from NARC site

  18. 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. Evaluation of fungicides for control of stem rust in Montana, 2010. Plant Disease Management Reports 4: CF037. (Funded by MWBC, 2009) • K. McVay, M. Burrows, F. Menalled, K. Wanner. 2010. Montana wheat production guide. MSU Extension Publications EB0197. • Upcoming: lots more!

  19. 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?
