Sericea lespedeza continues to be a major concern on rangeland, pasture, and some CRP acres in Kansas. It is a statewide noxious weed in Kansas and therefore needs to be controlled. Sericea lespedeza has a tremendous seed bank that helps reestablish stands.
There are no known biological controls that can be effectively used on sericea lespedeza. However, grazing with goats can suppress sericea lespedeza stands and produce a saleable product. It takes 4 to 5 goats per acre (of sericea) to graze the plant heavily enough to eliminate seed production. Cattle supplemented with corn steep liquor (CSL) have been shown to consume more sericea lespedeza than animals not supplemented with CSL. Current studies are underway to determine the impact of late summer grazing by sheep on sericea lespedeza. Continue reading “Sericea Lespedeza Pasture Control”
