Managing Weeds

Unit 1.10 | Part 1 – 415

6. Describe three additional weed manage-
   ment techniques, how they function, and
   how they may be used in organic farming
   systems.

• Irrigate stale beds (beds that have been
  formed but not planted) to germinate
  weeds and use flame weeder to kill newly
  germinated broadleaf weeds prior to planting
  crops


• Use flamer on beds of slow-germinating crops
  such as garlic and carrots after irrigation
  and before crop emergence to kill newly
  germinated broadleaf weeds


• Soil solarization suppresses weeds by
  elevating soil temperatures high enough to
  kill weed seeds


• Dark plastic mulches suppress weeds by
  blocking light and as a physical barrier
