“…There were no effects of herbicides applied in July on the establishment of the same grass species studied in November (unpublished data, P = 0.05), confirming that the shorter, September 2-mo interval application timing was the appropriate residual interval target. Several studies have demonstrated improved native grass species establishment with the use of selective herbicides Bahm et al , 2015Martin et al 1982;Masters et al 1996), but there has been limited research on the potential carryover effects of broadleaf herbicides, particularly aminopyralid, on the establishment of native grass seedlings. Aminopyralid is a viable alternative for controlling susceptible invasive forbs in an integrated program to establish grasses in the upper Midwest tallgrass prairie region.…”

“…However, treatments that resulted in the best establishment and highest biomass production varied by herbicide, grass species, and location of the study. Bahm et al (2015) reported improved stand establishment of native grass seedings in South Dakota when weeds were controlled with herbicides during establishment. Reseeding desired species following weed control can also improve long-term restoration (Mangold et al 2015).…”

Invasive species management is often more successful if desirable species are seeded after the target weed is controlled. However, control of invasive plants must be maintained following reseeding or the seeded species may fail to establish. A regional study conducted in Minnesota, North Dakota, and South Dakota evaluated the effect of aminopyralid, clopyralid, or picloram applied in the fall prior to fall-dormant seeding or seeding the following spring on cool- and warm-season native grass species establishment. Herbicides were applied at standard rates used to control invasive broadleaf weeds in the upper midwestern tallgrass prairie region of the United States. Cool-season species included Canada wildrye, green needlegrass, and intermediate wheatgrass. Warm-season species included big bluestem, little bluestem, sideoats grama, switchgrass, and Indiangrass. Aminopyralid did not reduce seedling establishment in either fall or spring seeding. Grasses generally were not affected by a pretreatment of the pyridine standards clopyralid or picloram either, with the exception of a slight reduction in fall-seeded establishment of intermediate wheatgrass. Picloram also slightly reduced fall-seeded establishment of Canada wildrye. Application of aminopyralid can safely be used to control susceptible invasive species preceding grass species establishment, with a safety margin similar to or slightly better than that with the pyridine standards clopyralid or picloram.
