Resumen: La roya de la hoja de trigo (RH), causada por Puccinia triticina Ericks, es una de las enfermedades del cultivo más prevalentes en Uruguay y otros países del Cono Sur. En epidemias severas se han estimado pérdidas de rendimiento de más de 50 % y pueden ser necesarias dos o más aplicaciones de fungicidas para controlar la enfermedad en cultivares susceptibles. Los estudios de la variabilidad del patógeno son importantes para determinar su rango de virulencia, para inferir el mecanismo de su variación, determinar el origen y dispersión de los patotipos y confirmar la presencia de nuevas razas inferidas por el cambio de comportamiento del hospedero. El objetivo de esta investigación fue estudiar la diversidad en la población de P. triticina en Uruguay durante 2011 y 2012. Se estudiaron un total de 363 muestras de RH recolectadas en diferentes momentos de distintos cultivares y localidades de la región del cultivo. La prevalencia de las 22 razas identificadas (de mayor a menor frecuencia MFP; TDT-10,20; MDP; MDT-10,20; TFT-10,20; MFP-20; MFP-10,20; MDP-20; DBB-10,20; MKD-10; TPR-20,39; MFT-10,20; MDP-10,20; MDR-10,20; MFT; MDT; MFP-10; MHJ-10; MJD10; TMD-10,20; MCP; MFR-10,20), se relacionó a su virulencia sobre los cultivares utilizados por los agricultores. La presencia o frecuencia de las razas varió entre años, zonas y momento de recolección. Se reportan por primera vez las razas DBB-10,20, MHJ-10, MJD-10, MKD-10, TMD-10,20 y TPR-20,30, no previamente detectadas en Uruguay. Este estudio permitió confirmar que la población del patógeno presente en Uruguay es diversa y continúa evolucionando.
Summary: Leaf rust (LR), caused by Puccinia triticina Ericks, is one of the most prevalent wheat diseases in Uruguay and other countries of the Southern Cone. The economic importance of the disease is clear considering that, in severe epidemics, grain yield losses of more than 50 % have been determined and that two or more fungicide applications are necessary to control the disease in susceptible cultivars. Studies on the pathogen variability are important to determine its range of virulence, infer the mechanism of its variation, determine the origin and spread of pathotypes, complement the knowledge of the resistance of commercial cultivars, confirm the presence of new races inferred by change of the host reaction, and identify races important for breeding and specific studies. The objective of this research was to study the diversity in the P. triticina population in Uruguay during 2011 and 2012. A total of 363 LR samples collected at different times from different cultivars and locations of the crop area were studied. The prevalence of 22 identified races (higher to lower frequency: MFP; TDT-10,20; MDP; MDT-10,20; TFT-10,20; MFP-20; MFP-10,20; MDP-20; DBB-10,20; MKD-10; TPR-20,39; MFT-10,20; MDP-10,20; MDR-10,20; MFT; MDT; MFP-10; MHJ-10; MJD-10; TMD10,20; MCP; MFR-10,20), was related to the virulence on cultivars used by farmers. The presence or frequency of the races varied among years, zones and time of collection. Two races not epreviously reported were detected. This study confirmed that the pathogen population present in Uruguay is diverse and continues to evolve.

ABSTRACT.
Citrus fruits and their by-products such as concentrated juices and essential oils are important intermediate by-products in the food industry that can selectively accumulate plant protection agrochemicals employed in their production. They are very difcult matrices for pesticide residue analysis due their high number and concentration of phytochemicals that could hamper the determinations. The fruit processing leads to the concentration/dilution or elimination of some of these natural products that change totally the nature of the matrix where the pesticides partition unevenly. Looking at the industrial process of the fruit, a unifed vision for the pesticide residues analysis throughout the lemon fruit chain production, useful for the routine analysis of the above mentioned three matrices is presented. The driven concept is the minimization of matrix efects through sample dilution of the concentrated by-products, either after sample treatment or not. This approach will contribute to the maintenance of the whole instrumental system. QuEChERS AOAC 2007.01 was selected as the most suitable protocol for routine determination of, residues of 16 the pesticides most commonly used in the fruits during the citrus production through liquid chromatography coupled to tandem mass spectrometry (LC?MS/MS). The same protocol was applied for pesticide residue analysis in concentrated juice after diluting 4 times the sample to minimize the matrix efects. For the analysis of lemon essential oils, the dilution and shoot procedure proved to be useful for LC?MS/MS and gas chromatography?mass spectrometry determination. The three methodologies were validated following SANTE guidelines, with quantitation limits below the established European Union and Codex Alimentarius maximum residue limits. The developed methodologies are useful tools for the routine control analysis of pesticide residues in lemon matrices, allowing high sample throughput and enhancing labs productivity.
