Control of Sericea Lespedeza Using Late-season Prescribed Burning

We evaluated prescribed fire in either August or September as a control measure for sericea lespedeza invasion of native rangeland.  Two years of data indicated substantial reductions in stand vigor, canopy frequency, and seed production of sericea lespedeza compared with conventional spring burning, all without the use of herbicides. Late-season prescribed burning allowed for significant forage regrowth prior to winter dormancy. Native plant species composition was not influenced by burn treatment.  . Substantial reductions in canopy frequency and seed production of sericea lespedeza occurred when compared with conventional spring burning, all without the use of herbicides or changes in native plant composition.
