Cultural Management

  • Keep foliage dry. Locate your garden where it will receive morning sun.
  •  Allow extra room between the plants, and avoid overhead watering, especially late in the day.
  • Purchase certified disease-free seeds and plants.
  • Destroy volunteer tomato and potato plants and nightshade family weeds, which may harbor the fungus.
  • Avoid sprinkler irrigation, if possible, because it favors the development of late blight.
