  28. System A Check
  29. New Systems Potential BENEFITS: Outstanding pest control. Equal cost or slightly lower??? Reduced buffer restrictions. Far more consistent. No herbicide under mulch. Lower odor concerns.
  30. New Systems Potential NEGATIVES: 2 or 3 fumigants; 2 application points Shank inject 4 inches on bed top Slower application than Trifecta, Pic Chlor Plant back interval longer

  35. Fumigant Plant Back Intervals PEST CONTROL PLANT BACK
  36. Factors Influencing Rate/Control FUMIGANT RATE 1. 1. Higher populations of nutsedge 2. Warmer soil temperatures 3. Low moisture conditions (not wet either) 4. Soft bed (compaction)—double press?? 5. Lighter texture the soil
  37. Factors Influencing Rate/Control FUMIGANT RATE 1. 1. Higher populations of nutsedge 2. Warmer soil temperatures 3. Low moisture conditions (not wet either) 4. Soft bed (compaction) 5. Lighter texture the soil INFLUENCE CONCENTRATION OVER TIME
  38. Factors Influencing Rate/Control FUMIGANT RATE 1. 1. Higher populations of nutsedge 2. Warmer soil temperatures 3. Low moisture conditions (not wet either) 4. Soft bed (compaction) 5. Lighter texture the soil We can influence quite quickly if willing!!!!
  39. Managing Nutsedge YEAR ROUND 1. Row middles with Sandea 2. Spray as soon as crop done:
  40. Roundup 2 qt/A fb 2 qt/A 10 days later! Then treat as needed.
  41. Amount of Sandea remaining on plastic mulch. TyTy GA, 2005. percent days Grey, Culpepper
  42. Managing Nutsedge YEAR ROUND 1. Row middles with Sandea 2. Spray as soon as crop done: 3. When mulch is out of field:
  43. ROTATE DISKING WITH ROUNDUP AND 1 QT 3WK AFTER NUTSEDGE EMERGENCE ADD SANDEA IN WITH ROUNDUP ONCE IF NOT CARRYOVER PROBLEMS
