Herbicide resistance is becoming more common in weed ecotypes and crop species including turfgrasses, but current gaps in knowledge limit predictive ecological risk assessments and risk management plans. This project examined the effect of annual glyphosate applications on the vegetative growth and reproductive potential of two weedy bentgrasses, creeping bentgrass (CB) and redtop (RT), where t...

Enhanced nitrogen use efficiency (NUE) in turfgrass systems comprises several factors, including more efficient uptake and assimilation of applied (N), as well reduced N losses to the environment. The objectives current research were evaluate inter- intraspecific variation parameters two Agrostis species, creeping bentgrass (Agrostis stolonifera L.) velvet canina L.), under field controlled env...

Rhizodeposition is considered a primary reason for the plant identity effect. However, the detection of distinct rhizosphere bacterial communities (RBC) with different plant species has been variable. The aim of this study was to examine the potential explanations for this variability using three perennial grassland species. In a Kansas field experiment, over two growing seasons, we sampled RBC...

Se aportan datos corológicos y nomenclaturales de algunas especies gramíneas la tribu Poeae (Poaceae) pertenecientes a los géneros Agrostis, Aira, Neoschischkinia Holcus.

Creeping bentgrass (Agrostis stolonifera) and redtop (A. gigantea) are introduced turfgrasses that are naturalized throughout the northern U.S. Interest in creeping bentgrass has risen following the 2003 escape of a genetically modified (GM), herbicide-resistant cultivar near Madras, Oregon. The objectives of this study were to characterize the floristic attributes of the plant communities asso...

It is common fallacy in Britain that 'American' golf greens are constructed of sand; are excessively irrigated, excessively fertilized, and that their surfaces are soft. Generalisations of 'American' golf greens cannot be made. The diversity in climates, maintenance budgets, construction methods, etc., results in a host of 'American' greens. The grass species on the greens may consist of Poa an...
