Grass selections including 10 zoysiagrasses, 18 paspalums, 34 Bermuda grasses, tall fescue, creeping red fescue, and perennial ryegrasses with and without endophyte were evaluated for potential resistance to fall armyworm, Spodoptera frugiperda (J. E. Smith), larvae. Laboratory evaluations assessed the degree of antibiosis among >70 grass lines to first-instar fall armvworms. When all parameter...

Teff [Eragrostis tef (Zucc.) Trotter] is a relatively new forage crop that is attracting much interest among hay growers in the United States and Utah (Creech, et al., 2012). Teff plants have fine stems, shallow roots and are not frost tolerant. This annual, warm-season grass grows best during the hottest months of the year when cool-season grasses suffer their “summer slump.” Since Teff does n...

A thin-layer chromatographic method is described for the semi-quantitative detection of oxalate in tropical grasses. The method allows the processing of large numbers of samples and should be sufficiently accurate for most screening requirements. High specificity and sensitivity for oxalate is achieved with simple laboratory equipment, but strict quantitation requires the use of a gas chrornato...

Vigorous Summer Growth Peak growth of these grasses occurs during summer. They break dormancy in late March and early April and then grow rapidly from mid-May through midsummer. In late summer, growth slows until fall dormancy, usually in October. The maturity dates of the various species vary somewhat, but all follow this pattern. They remain dormant through winter. Five Key Species While ther...

Strains of Xanthomonas translucens pv. graminis cause bacterial wilt on several forage grasses. A draft genome sequence of pathotype strain CFBP 2053 was generated to facilitate the discovery of new pathogenicity factors and to develop diagnostic tools for the species X. translucens.

The nutrient quality of forage, particularly perennial warm-season grasses, is often lacking in trace mineral content to supply the requirements of most all classes of grazing cattle. Since forage is the most significant contributor to the trace mineral nutrition of grazing beef cattle, it is important to consider these deficits and how they may impact the performance of the cattle consuming th...

Herbivores generally have strong structural and compositional effects on vegetation, which in turn determines the plant forage species available. We investigated how selected large mammalian herbivore assemblages use and alter herbaceous vegetation structure and composition in a southern African savanna in and adjacent to the Kruger National Park, South Africa. We compared mixed and mono-specif...

Here, we report the draft genome sequence of the Xanthomonas bromi type strain LMG 947, an important pathogen of bromegrasses (Bromus spp.). Comparative analysis with other Xanthomonas spp. that are pathogenic on forage grasses will assist the analysis of host-plant adaptation at the genome level.
