Late-Season Options for Sericea Lespedeza Control
Sericea lespedeza is now flowering and beginning to set seed across parts of Kansas, but there is still an opportunity to manage this invasive perennial before the growing season ends.
Late-summer prescribed burning can reduce sericea cover and seed production, although current moisture conditions and the amount of time remaining for vegetation to regrow before frost should be considered. Sheep and goats can also be useful management tools, as they readily consume sericea and grazing at this time of year can help reduce seed production.
Herbicide selection changes as the plant matures, too. Products commonly used earlier in the summer may become less effective once sericea begins flowering, while metsulfuron-containing products can be more effective during later growth stages.
Often, the best results come from combining approaches such as grazing, prescribed fire, mowing or haying with a properly timed herbicide treatment. Sericea management is rarely a one-and-done project, so follow-up next growing season is important.
