“…In our study, established Bowie buffalograss was most tolerant to carfentrazone + quinclorac, halosulfuron, indaziflam, quinclorac, quinclorac + MCCP + dicamba, simazine, sulfosulfuron, or thiencarbazone + iodosulfuron + dicamba. This research, combined with our previous study of herbicide use on newly seeded buffalograss (Li et al, 2015), show that a wide range of herbicides can be safely applied to buffalograss at many different growth stages.…”

Core Ideas Proper calibration and application is important when using herbicides on buffalograss. Established ‘Bowie’ buffalograss was most tolerant to carfentrazone + quinclorac, halosulfuron, indaziflam, quinclorac, quinclorac + MCCP + dicamba, simazine, sulfosulfuron, or thiencarbazone + iodosulfuron + dicamba. Herbicide injury on established buffalograss is relatively short‐lived with the exception of imazapic at the 2× rate.

Mesotrione (2-[4-(methylsulfonyl)-2-nitrobenzoyl]-1,3-cyclohexanedione) is a proven effective weed control product in agricultural and turf settings but its use within a hydroseeding mixture has not been investigated. Two experiments were conducted to evaluate the effects of (1) mesotrione rate and (2) duration of herbicide exposure on turf establishment and weed populations through hydroseeding establishment methodology. The experimental design of both studies was a randomized complete block, incorporating a split-plot in the second study, with four replications and repeated in two years. Perennial ryegrass (Lolium perenne L., variety not stated) was hydroseeded on a silt loam soil (pH 7.0) in summer at 39 g m −2 in a slurry delivering 6.1 L m −2. Treatments in the first study were mesotrione rates of 0.000, 0.088, 0.175, and 0.263 kg a.i. ha −1. Treatments in the second study were duration of mixture in tank before applying of 0, 2, and 4 h, with and without mesotrione at 0.175 kg a.i. ha −1. Turfgrass percent cover, turfgrass injury, and weed populations were assessed for both studies. The addition of mesotrione at any rate to the hydroseeding slurry did not reduce desired turf populations; in many cases, the amount of desired turf cover increased. Weed populations were significantly reduced by all mesotrione rates; the effect was most evident at the two highest rates. No treatments caused turf injury. Length of time in the hydroseeding slurry did not reduce herbicide efficacy or desired turf populations, or cause turf injury.

“…Despite its resilience in low‐input management, buffalograss is still susceptible to encroachment by weeds that can reduce aesthetics and traffic tolerance (Brosnan et al., 2014). Previous research has demonstrated safety of seedling and established buffalograss to spring and summer applications of pre‐emergence herbicides (Dotray & McKenney, 1996; Fry et al., 1997) and postemergence herbicides (Fry et al., 1997; Goss et al., 2006; Li et al., 2015; Li et al., 2017; Li et al., 2018; Van Dyke & Johnson, 2009). Additional research demonstrated the safety of postemergence herbicide applications on buffalograss entering winter dormancy (Braun et al., 2018).…”

Buffalograss [Buchloe dactlyoides (Nutt.) Engelm.] is gaining popularity as a turfgrass for low maintenance sites, where irrigation and regular mowing or fertility may not be available. Unfortunately, weed species also thrive in low maintenance sites. This field study was conducted to assess the utility of glyphosate as a selective herbicide in newly established buffalograss. Buffalograss (cultivar Cody) burs were sown into newly renovated sites in Fayetteville, AR, in the summer of 2017 and 2018. Glyphosate was applied at 1, 3, and 8 weeks after emergence (WAE) of buffalograss seedlings at rates of 0.15, 0.325, 0.75, 1.5, 3.0 lb a.e. acre–1 of glyphosate and one untreated control. These rates correspond to 0.1 time (×), 0.25×, 0.5×, 1.0×, and 2.0× of the highest labeled rate of 1.5 lb a.e. acre–1 of glyphosate (64 fl oz acre–1, RoundUp Pro, Bayer Cropscience). Following application, plots were assessed using visual ratings of turf quality on a 1–9 scale at weekly intervals for 10 weeks. One week after applications at 8 WAE, images were taken of each plot and analyzed for dark green color index (DGCI) as a quantified measure for the green value of living foliage in treated areas. In both years and all application timings, buffalograss turf quality was reduced to an unacceptable quality when treated with glyphosate at 0.25× of the maximum labeled rate and above. At the 0.1× rate of glyphosate, buffalograss turf quality was not significantly reduced in either year at any application timing.
