1. Use 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.

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.
