Three herbicides were evaluated for use in seeding range grasses. Propazine, applied as a pre-emergence at rates up to 3.0 lb/acre, controlled broadleaf weeds and crabgrass but had no apparent retarding effect on the germination and growth of switchgrass and Old World bluestems. Siduron applied at 1.5 lb active ingredient/acre controlled large crabgrass and had no apparent retarding effect on switchgrass, big bluestem, and indiangrass. Sideoats grama was harmed by all pre-emergence herbicides tested. Norea applied at 2 lb/acre retarded germination and seedling establishment of those species tested. None of the herbicides tested has been cleared for use on grazing lands.
