Kochia (Kochia scoparia)

Kochia
This weed has consistently been one of the top three worst weeds in ND, MB, KS and SD. It is a highly competitive weed. It emerges throughout the production season during cool periods in early spring or later with warm temperatures and good moisture. It can have a significant impact on yield and is a great producer of seed. It has developed resistance to ALS herbicides which complicates the control strategies in sunflower.

Control Strategies

Kochia
1. Good control of Kochia in the previous year's crop

2. Use a burn down up to emergence

3. Spartan has excellent Kochia control and can be used in reduced and no till systems

4. Eptam, Prowl, Sonalan and Trifluralin control of Kochia are rated as fair

5. Beyond¹ and Express² have excellent control but will not control resistant ALS Kochia

6. Between row cultivation is best when Kochia is small

7. Between row cultivation or hooded sprayer with herbicide application
