The ability to control kochia continues to be a struggle. WinField United Regional Agronomist Ryan Peterson sees kochia as a problem that just keeps building on itself. “It’s not new; it’s something we’ve been battling for the last 25 or 30 years.” Group 2 resistance was seen first. That was followed by glyphosate resistance in the last ten-to-12 years. “Anytime that we’re talking kochia, we really have to talk about a long-term strategy, it’s not a single application anymore.” Crop rotation can be part of the kochia management plan.
