Glufosinate + Lactofen is Likely an Effective Mixture to Manage Kochia Postemergence in Soybean

Kochia is a difficult to manage weed that infests crops across South Dakota. Herbicides are the most effective and efficient tactic to manage kochia. However, overreliance on single herbicide active ingredients (such as glyphosate [Roundup] and imazethapyr [Pursuit]) have resulted in resistant populations. Mixing effective herbicides is a tactic that can reduce selection pressure on resistant weeds and increase the effectiveness of weed management.

Dicamba (Engenia, Xtendimax, Tavium) products labeled for tolerant soybean varieties had great utility in managing herbicide-resistant kochia. However, due to the registration being pulled for these products, many South Dakota soybean farmers now have few options for effective postemergence herbicide. Glufosinate (Liberty) and lactofen (Cobra) are effective on kochia when applied timely (2 to 4” weeds). While effective, farmers are highly encouraged to not apply these herbicides alone and recurrently as to not select for resistant weeds.

Video: On the Ground with FMC: Adastrio Fungicide

On the Ground with FMC, Brownfield Reporter Erin Anderson talks with Southern Indiana growers Jeff Sailor and Andy Lowry about their experiences using Adastrio® fungicide and its role in their crop management plans.

After participating in spray drone trials, Jeff found that Adastrio stood out among the products tested. As harvest approaches, he remains optimistic about the product’s performance and its role in helping protect yield potential.

Andy Lowry discusses how a successful trial led him to use Adastrio across his entire farm. He highlights the product’s disease control and coverage, particularly against early gray leaf spot and southern rust. Andy also points to visible differences in crop health between fields treated with Adastrio and those left untreated.
