Integrated Plant Management C&P

  1. 1. Justin C. Ruiz, CGCS Integrated Plant Management Practical IPM on the Golf Course
  2. 3. Being Creative
  3. 4. Integrated Plant Management <ul><li>Defined </li></ul>“ IPM is a sustainable approach to managing pests by combining biological, cultural, physical and chemical tools in a way that minimizes economic, health, and environmental risks.” Reference: http://www.ag.ndsu.nodak.edu/aginfo/ndipm/ipmdefinition.htm
  4. 5. Presentation Outline <ul><li>Growing Degree Day Calculation </li></ul><ul><li>Billbug Control </li></ul><ul><ul><li>Degree Day Model </li></ul></ul><ul><ul><li>Scouting </li></ul></ul><ul><ul><li>Chemical Application </li></ul></ul><ul><li>Cutworm Control </li></ul><ul><ul><li>Degree Day Model </li></ul></ul><ul><ul><li>Scouting </li></ul></ul><ul><ul><li>Chemical Application </li></ul></ul>
  5. 6. Presentation Outline <ul><li>Masked Chafer </li></ul><ul><ul><li>Degree Day Model </li></ul></ul><ul><ul><li>Scouting </li></ul></ul><ul><ul><li>Chemical Application </li></ul></ul>
  6. 7. Growing Degree Day <ul><li>“ The number of degrees the average temperature is above a baseline temperature. Used to predict insect and plant development.” </li></ul>
  7. 8. Upper and Lower Threshold Temperature <ul><li>“ The high and low temperature at which insect/plant development occurs.” </li></ul>
  8. 9. Calculating Growing Degree Days (GDD) T max + T min GDD = ____ 2 -T base T max = Daily High T min = Daily Low T base = 50 degrees <ul><li>Sine Wave Method is more accurate. You can find calculators on the web. </li></ul>
