Managing Resistant Kochia

BURLINGTON, CO – December 15, 2016 – Here are ten things you can to do to manage resistant kochia:

  1. Use herbicide tank mixes. Efficacy on kochia will increase.
  2. Use full labeled herbicide rates.
  3. Apply post-emergent tank mixes to kochia before the weed is 6 inches tall.
  4. Actively growing kochia is easier to control than weeds that are under moisture stress.
  5. Apply herbicides with 3 to 10 gallons per acre water.
  6. Use recommended additives and adjuvants.
  7. Flat fan nozzles are recommended. Other types can work effectively also.
  8. Re-apply herbicides as later kochia flushes emerge.
  9. Rotate crops along with herbicides.
  10. Follow all manufacturer recommendations to enhance coverage and minimize drift risk.
