Program '11: The Best Fungicide Program for YOUR Putting Greens Program '11: The Best Fungicide Program for YOUR Putting Greens Presentation Transcript

  • Program ’11: The best fungicide programfor YOUR putting greensLane TredwayAssociate Professor and Extension SpecialistDepartment of Plant PathologyNorth Carolina State University
  • 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
  • The diagnosticlab saw some bacteria in our samples.
  • Which bacteriadid they see? Is it a pathogen? The diagnostic lab saw some bacteria in our samples.
  • Which bacteria did they see? Is it a pathogen? The diagnostic lab saw some bacteria They didn’t say, but in our samples.clearly we have a huge bacteria problem here.
  • Acidovorax sp.Xanthomonas translucensNo suspected pathogens
  • Identifying the Acidovorax species associated withcreeping bentgrass putting greens.
  • Bacteria Research Plans for 2011 • closing in on an identification for the Acidovorax species associated with creeping bentgrasss • inoculations of field plots with Acidovorax and Xanthomonas isolates to determine their pathogenicity • evaluation of antibiotics and other compounds as possible control practices
  • The problems in 2010 actually started in May. 7Cumulative Rainfall (in.) 5.25 3.5 1.75 0 Jan Feb Mar Apr May Jun Jul Aug Sept Oct Nov
  • Pythium root rot
  • Many fungicide programs are weak against Pythium. May 13 Headway (1.5 fl oz) May 27 Concert (4.5 fl oz) June 10 Renown (4.5 fl oz) June 24 Daconil + Fore (3.2 + 4 oz) July 8 Medallion + Concert + Signature (0.25 + 4.5 + 4) July 22 Renown + Fore (4.5 + 4 oz) August 5 Medallion + Concert + Signature (0.25 + 4.5 + 4) August 20 Daconil + Fore (3.2 + 4 oz)
  • Pythium root rot is driven by soil moisture.
  • Program 13 offers no Pythium root rot protection. May 22 Tartan (2 fl oz) June 5 Insignia (0.9 oz) June 19 Spectro (5.76 oz) July 3 Signature + Daconil (4 + 3.2 oz) July 17 Insignia (0.9 oz) July 31 Signature + Daconil (4 + 3.2 oz) August 14 26GT (4 fl oz) August 28 Tartan (2 fl oz)
  • “It can’t be a disease because I’m on Program 13!”
  • “I sprayed Eagle because I’m on Program X andit was on the schedule.”
  • Spray programs are not uncommon in agriculture.flickr:TaminaMiller
  • Every golf course is different.Climate, microclimate,expectations, andmanagement styles vary.
  • Art and Science
  • Where’s the art in this?
  • Let’s put the art back indisease control!
  • Program ’11 How to develop and implement a fungicide program.
  • Program ’11 How to develop and implement a fungicide program. 1. develop list of diseases based on location, cultivar, soil type, and history
  • Program ’11 How to develop and implement a fungicide program. 1. develop list of diseases based on location, cultivar, soil type, and history 2. use historical weather data to determine when each disease is ‘normally’ active
  • Program ’11 How to develop and implement a fungicide program. 1. develop list of diseases based on location, cultivar, soil type, and history 2. use historical weather data to determine when each disease is ‘normally’ active 3. select product(s) that will control the disease(s) that are expected to be active each week
  • Program ’11 How to develop and implement a fungicide program. 1. develop list of diseases based on location, cultivar, soil type, and history 2. use historical weather data to determine when each disease is ‘normally’ active 3. select product(s) that will control the disease(s) that are expected to be active each week 4. select rates, intervals, and application method
  • Program ’11 How to develop and implement a fungicide program. 1. develop list of diseases based on location, cultivar, soil type, and history 2. use historical weather data to determine when each disease is ‘normally’ active 3. select product(s) that will control the disease(s) that are expected to be active each week 4. select rates, intervals, and application method 5. adjust as needed based on actual weather conditions
  • 1. What diseases do you need to control?• ‘A-1’ creeping bentgrass• established in 2005• USGA construction dollar spot Pythium root rot algae brown patch fairy ring Pythium root dysfunction
  • 2. What conditions favor these diseases?Pythium root dysfunction - average daily soil temperaturesbetween 50ºF and 70ºFfairy ring - average daily soil temperatures between 55ºF and65ºFdollar spot - low temperatures above 50ºFalgae - high temperatures above 80ºFbrown patch - low temperatures above 60ºFPythium root rot - wet soils
