Plan now for volunteer corn control

There can be debate on whether volunteer corn is truly a weed, but it can certainly be a problem in fields following corn.

Be on the lookout for Soybean Gall Midge

In 2023, soybean gall midge was found infesting soybean and sweet clover in Marshall and Nemaha counties in Kansas. Since this pest can overwinter in Kansas, producers should be on the lookout for additional infestations in 2024. Scouting for this pest should start when the plants are at the V2 growth stage.

Control options for buckbrush, roughleaf dogwood, and smooth sumac

Three common brush species native to Kansas and widely spread across the state are buckbrush, roughleaf dogwood, and smooth sumac. These shrubs can produce clumps that will shade out and reduce forage production. Be on the lookout for these plants and implement a control plan if needed.
