Se llevó a cabo un estudio de caso enmarcado en un proceso de investigación cualitativa, en torno a la Mesa de Desarrollo Rural de Laureles-Cañas, Tacuarembó. Para ello se utilizaron métodos cualitativos de investigación social como entrevistas abiertas estandarizadas y mapeo de actores sociales. La primera conclusión es que no existe una metodología pre-establecida para el trabajo en las MDR. Por otro lado, se identifica una visión enmarcada en el desarrollo rural con enfoque territorial. Otra de las conclusiones es que existen importantes actores del medio que no participan de las MDR, como las empresas forestales o los asalariados rurales. Asimismo, se dentificó la relevancia de los liderazgos locales y que existen ciertos problemas de representatividad de los delegados. Se establece un lineamiento sugerido de
trabajo en las MDR mediante capacitaciones, mapeos de actores y establecimiento claro del ámbito como tal. Abstract: A case study was carried out within a qualitative investigation process, concerning the Laureles-Cañas Rural Development Round Table (MDR), in Tacuarembó. Qualitative Methods of Social Investigation were used, such as open standardized interviews and mapping of social actors. The first conclusion arrived at is that there is no previously stated methodology in order to work with the MDRs. On the other hand, the Territorial Rural Development Scope was identified as the main vision implied in these Round Tables. Another conclusion arrived at was that there are relevant social actors that do not participate in these meetings, such as forestry companies or wage earners. Furthermore, local leaderships
were identified to be of relevant importance and it was also identified that there are certain representative issues. It is suggested that these MDR should use training methodologies, mapping of social actors and the clarifying of the aim of these meetings.

ABSTRACT:Fusarium Head Blight (FHB) is a major constraint to barley production that substantially reduces yield and grain quality. FHB is also a major food safety concern because FHB pathogens contaminate grain with trichothecenes and other mycotoxins. DNA sequence-based analyses and in-vitro toxin assessments were used to characterize the species and trichothecene chemotype composition of FHB pathogens on barley in Uruguay. F. graminearum was the dominant species (89.7%), and three other members of the F. graminearum species complex (FGSC) were identified as FHB pathogens of barley in Uruguay for the first time. Other minor contributors to FHB species diversity included F. poae, F. avenaceum, F. pseudograminearum and an unnamed species from the F. incarnatumequiseti species complex (FIESC). Most isolates (89.7%) had the 15-acetyldeoxynivalenol (15-ADON) trichothecene type. However, the results expanded the known area of occurrence within Uruguay for the nivalenol (NIV) toxin type, which was observed among isolates from three species of the FGSC, F. pseudograminearum, and F. poae. Isolates with the 3-acetyldeoxynivalenol (3-ADON) or NX-2 toxin types were not observed, although a previously published multilocus genotyping assay was updated to identify NX-2 strains. Analyses of population structure and comparisons with FHB isolates from wheat in Uruguay indicated that F. graminearum constitutes a single genetic population with no evidence of population differentiation related to the sampled hosts. Inter and intraspecific differences were observed in aggressiveness toward four barley genotypes with different levels of resistance to FHB, and in general nivalenol producers were the least aggressive isolates. Sensitivity to metconazole was approximately 10 times higher than was detected for tebuconazole. This is the first report regarding tebuconazole and metconazole sensitivity for Fusarium species causing FHB in barley in Uruguay, and constitutes an important starting point for monitoring temporal or spatial changes in FGSC sensitivity, which is critical to define FHB management practices.
