| Abstract/Contents: | "The addition of adaptable perennial grasses typically referred to as "native species" to golf courses is a relatively new practice. Unlike conservation efforts, golf courses must establish cover quickly for aesthetics and weed control. Utilizing methods such as increased seeding rates and scheduled watering can expedite the maturation of the stand but weeds still pose a constant problem. Herbicides are critical to promote development of slow-maturing perennial grasses by reducing weed competition. The selection of herbicide depends on its effectiveness and level of tolerance by the grass species. Evaluating the effects of commonly used herbicides on blue grama grass (Bouteloua gracilis) and little bluestem grass (Schizachyrium scoparium) can provide data necessary to make herbicide selection easier while protecting the developing stand. Our objectives were to evaluate 25 herbicides or herbicide combinations for effects on blue gramma grass and little bluestem. Little bluestem and blue grama grass were seeded in rows at 50 pounds of seed per acre on June 22, 2007 in Blacksburg, VA. Initial plant densities ranged from 1 to 78 blue grama plants and 18 to 103 little blues tem plants per plot. The study was established as a randomized complete block design with 3 replications and 26 treatments. Little bluestem and blue grama grass had a minimum of three leaves at time of application. Herbicides included in this study are: Amicarbazone; aminopyralid; bentazon; carfentrazone; carfentrazone + 2,4-D + MCPP + dicamba; chlorsulfuron; 2,4-D + MCPP + dicamba; fenoxaprop; flazasulfuron; fluazifop; flucarbazone; foramsulfuron; halosulfuron; imazapic; mesotrione; metsulfuron; nicosulfuron; primisulfuron; quinclorac; simazine; sulfentrazone; sulfosulfuron; temb otrione; topramezone; and trifloxysulfuron. All herbicides were applied with appropriate adjuvant and at label-recommended rates for crops on which the products are registered. Blue grama grass and little bluestem injury and plant densities were assessed weekly for 6 week by visually estimating plant discoloration stand reduction, and stunting compared to the non-treated control and by plant counts. Little bluestem was not significantly injured by the following: aminopyralid; bentazon; carfentrazone; carfentrazone + 2,4-D + MCPP + dicamba; chlorsulfuron; 2,4-D + MCPP + dicamba; fenoxaprop; flazasul furon ; fluazifop; foramsulfuron; ; halosulfuron; imazapic; nicosulfuron; primisulfuron; simazine; sulfentrazone; sulfosulfuron and topramezone. Amicarbazone; flucarbazone; mesotrione; metsulfuron; tembotrione and trifloxysulfuron injured little bluestem 40% or more. Blue grama grass was not significantly injured by the following herbicides: bentazon; carfentrazone; 2,4-D + MCPP + dicamba; fenoxaprop; fluazifop; flucarbazone; and simazine. All other herbicides caused unacceptable injury to blue grama grass. These data indicate that several herbicides are safe to use on these adaptable perennial grasses." |
