  • 2. North Carolina is in the ‘transition zone’. http://www.extension.org/pages/13152/transition-zone-lawns
  • 3. Creeping bentgrass is a cool-season grass.
  • 4. Creeping bentgrass is susceptible to a variety of pathogens.
  • 5. Heat imposed severe stress on creeping bentgrassgreens in 2010. 30 departure from normal HIGH temperature departure from normal LOW temperature 22.5 Departure from Normal (F) 15 7.5 0 -7.5 -15 -22.5 May June July August Sept Oct

  • 10. Too many fungicidesto choose from! flickr:kanickmoses
  • 11. “It can’t be a disease because I’m on Program 13!”
  • 12. “I sprayed Tartan because I’m on Program 13and that’s what was on the schedule.”
  • 13. Spray programs are not uncommon in agriculture.flickr:TaminaMiller
  • 14. Every golf course is different.Climate, microclimate,expectations, andmanagement styles vary.
  • 15. How do you decide when to make changes to your program? field observations online alerts diagnostic lab results reports from colleaguesreports from sales representatives weather conditions 0 25 50 75 100 % of respondents NC superintendents with creeping bentgrass greens (63)
  • 16. How can we get the message through?flickr:verbeeldingskr8
  • 17. Integrating Social Media and Other WebUtilities in ExtensionLane TredwayAssociate Professor and Extension SpecialistDepartment of Plant PathologyNorth Carolina State University
  • 18. What is Web 2.0? “The Web we know now, which loads into a browser window in essentially static screenfulls, is only an embryo of the Web to come. The first glimmerings of Web 2.0 are beginning to appear, and we are just starting to see how that embryo might develop. The Web will be understood not as screenfulls of text and graphics but as a transport mechanism, the ether through which interactivity happens. It will appear on your computer screen, on your TV set, your car dashboard, your cell phone, hand-held game machines, maybe even your microwave oven.” --Darci DiNucci in Fragmented Future (1999)
  • 19. Many sites incorporate Web 2.0 principles.
  • 20. Site traffic increases with disease pressure.
  • 21. Integration and workflow are key.
  • 22. Integration and workflow are key.
  • 23. How do superintendents follow turfdiseases.org? Page Referrals in 2010 Blogger 1. Facebook Email 2. Google 3. TurfNet Twitter Facebook 4. Twitter 5. PSU Turfgrass 6. Golf Course Industry 7. Google Images % of followers 8. Asian Turfgrass Center
  • 24. What does our site need to do? • interactive • news • alerts • events • presentations • publications • videos • images Why reinvent the wheel?
  • 25. Making it all work. • maintain a consistent identity • develop a workflow • organize links • use a password manager • turn off email alerts • pay attention to analytics • experiment!
  • 26. Who developed the fungicide program you used in 2010? I developed it. I don’t know. current or former supervisor colleague university researcher sales representative golf course superintendents (121)
  • 27. Which is your primary tool for fungicide selection? sales representatives product labels Chemical Control of Turf Diseases university personnel Disease Profiles on TurfFIles Disease Management Utility colleagues Pest Control for PTMs NC superintendents with creeping bentgrass greens (63)
  • 28. Disease Management Utility on TurfFiles turffiles.ncsu.edu/diseasemgmt
  • 29. Disease Management Utility on TurfFiles turffiles.ncsu.edu/diseasemgmt
  • 30. For which diseases do you spray fungicides preventively? algae anthracnose brown patch brown ring patch copper spot Curvularia blight dollar spot fairy ring large patch leaf spot pink snow mold Pythium blight Pythium root dysfunction Pythium root rot rapid blight red thread spring dead spot summer patch take-all patch yellow patch yellow tuft 0 15 30 45 60 # of respondents NC superintendents with creeping bentgrass greens (63)
  • 31. How often did you change your fungicide program in 2010? Never Rarely (<5x) Sometimes (5-10x) Frequenty (>10x) 0 5 10 15 20 25 30 # of respondents NC superintendents with creeping bentgrass greens (63)
  • 32. Comparing ways to develop and implementfungicide programs 1. Program 13 (Clemson) 2. BASF Program 3. Bayer Program 4. Syngenta Program 5. NC State Program 6. Program ’11 - treatments adjusted as needed based on weather conditions
  • 33. Conclusions • existing Web 2.0 services can be used effectively for extension communications • integration into a traditional website is possible • social media can increase your reach • golf course superintendents need more training in the development and implementation of fungicide programs
