Cultural Controls

  • Use certified plants only.
  • Set new plants in well-drained soil (no standing water in winter) where red stele has not been known.
  • Plant on beds raised 8 to 10 inches to improve drainage, or use drain furrows.
  • In home gardens or small plantings, raise the bed 15 inches.
  • Preplant soil solarization has been helpful in reducing populations of certain soilborne pathogens and weeds in western Oregon.
  • Place clear plastic (preferably anti-condensation film) directly on smooth, rototilled ground, which has been irrigated to field capacity and then allowed to drain for 1-2 days.
