“…Hordeum spp. is a genus of the Poaceae family widely distributed in the world, from Africa, Europe, and Asia to Central and North America [1,2]. In this genus, there are species with different reproduction systems ranging from highly autogamous to allogamous with genetic self-incompatibility [3], and also including both annual and perennial species [1].…”

Resistance Evolution to EPSPS Inhibiting Herbicides in False Barley (Hordeum murinum) Harvested in Southern Spain

et al. 2020

A failure of the EPSPS-inhibiting herbicide glyphosate to control several populations of Hordeum murinum subsp. leporinum (or H. murinum) occurred in southern Spain after more than fifteen applications in both crop (olive, orchards, and citrus) and non-crop (dry areas, roadsides and ditches) areas. Eight out of 18 populations studied were resistant (R) to glyphosate with R factors higher than four based on GR50. These populations also had the highest values of LD50 and the lowest levels of shikimic acid accumulation. Two adjuvants tested increased glyphosate efficacy in both susceptible (S) and R populations thanks to better spray foliar retention. Moreover, PS I-, PS II-, and ACCase-inhibiting herbicides, in pre- or post-emergence, proved to be the best chemical alternatives with different sites of action (SoA) to control both S and glyphosate-R populations. This study represents the first report worldwide of glyphosate resistance in H. murinum found in very different crop and non-crop areas from southern Spain. To design chemical strategies to implement integrated weed management programs for glyphosate-R H. murinum, both adjuvants and herbicides with alternative SoA as well as application timings should be considered.

“…Monographs and specific works were consulted for certain problematic taxonomic groups such as the genus Taraxacum [37]. The monograph by León E. et al [38] was consulted for the genus Hordeum. The work by Devesa et al was followed for Gramineae in general [39].…”

Impact of Grass Cover Management with Herbicides on Biodiversity, Soil Cover and Humidity in Olive Groves in the Southern Iberian

et al. 2021

In the present work, we studied the effect of herbicide use on extensive olive grove cultivation. To carry out this study, we analysed the effect that herbicide use had on biodiversity, vegetation cover and soil water content. For this purpose, 96 vegetation and soil sampling points were first taken, then georeferenced, and for each sampling point, several bioclimatic variables were interpolated. We concluded that the management of cover crops with herbicides over a long period of time resulted in a decrease in biodiversity, and the dominance of some species that were more resistant to herbicides was increased. Another finding was that the vegetation cover was reduced in the resampling in cases with herbicide management and that the location within the cropland (under the tree canopy, road, boundary or pasture) also has an influence. Finally, the study of soil moisture shows that soil water content was lower in the case of management with herbicides than in the case of management without herbicides. This loss of soil moisture was more accentuated and faster in areas with less vegetation cover. This work highlights the need to change the management models for tree crops in order to preserve biodiversity, soil quality and optimise water resources in a context of accelerated climate change in one of the regions most severely affected by global warming, the Mediterranean belt.

El Parque Nacional de Monfragüe tiene una superficie de 18.396 ha, su área periférica de protección de 116.160 ha, y su área de influencia socioeconómica de 195.502 ha. (BOE ley 1/2007 de 2 de marzo Anexo I a IV). El Parque Nacional y su área periférica de protección constituyen el núcleo central de la comarca biogeográfica de Monfragüe (distrito Vereño). Su área de influencia, mucho más amplia y con mayor variedad de substratos, participa en distinto grado de los distritos Vereño (comarca de la Vera), Cacereño, Coriano, Talaverano (comarca del Campo Arañuelo) y Villuerquino (comarca de los Ibores) (Rivas Martínez & Belmonte in Belmonte 2008). En su flora de la provincia de Cáceres, Rivas Mateos (1931), propuso unos 1.400 taxones vasculares para el área de estudio. Belmonte (1986), en su tesis doctoral, abarca una
