SUMMARY.
Several Diaporthe species are recognized as causal agents of many plant disease symptoms, including twig and branch cankers, dieback, shoot blight, and root and fruit rots. In Uruguay, the proximity between apple, pear and peach orchards offers the possibility to study the presence of different Diaporthe spp. associated with
wood cankers across different deciduous fruit trees. Symptomatic twigs and branches of these orchard species were sampled, and isolates of Diaporthe were obtained. Selected isolates were used for cross inoculations in the three hosts. Seven Diaporthe spp. were identified, based on the internal transcribed spacer (ITS) region of rDNA and the translation elongation factor 1-alpha gene (EF1-α) phylogenies. The species were: Diaporthe amygdali, D. foeniculina, D. infecunda, D. eres, D. terebinthifolii, D. oxe and D. phaseolorum, while two isolates Diaporthe sp. 1 and Diaporthe sp. 4 could not be assigned to any species. Diaporthe infecunda, D. eres, D. terebinthifolii, D. phaseolorum and D. oxe on Pyrus communis and D. foeniculina on Malus domestica represent new records in these hosts in Uruguay, while D. oxe isolated from Prunus persica is a new record for this species. Diaporthe eres and D. phaseolorum were the most virulent species, posing the greatest risk due to their wide distribution and virulence in apple and peach trees. Although pear trees showed less symptomatic tissues and were less susceptible than peach and apple trees in the pathogenicity tests, they harboured seven of the species, and therefore should be considered as reservoirs of Diaporthe in Uruguayan orchards. Trees of the three hosts could be considered potential reciprocal sources of pathogenic Diaporthe spp.

ABSTRACT.- Ramularia leaf spot (RLS) is primarily managed by foliar fungicide spraying, which can result in residues in the grain. In recent years, increasing attention has been paid to the risks these residues pose to consumers. This study aimed to evaluate the efficacy of fungicide management used for RLS control and their fungicide residues in barley grain. Four different alternatives of fungicide mixtures: fluxapyroxad + pyraclostrobin + epoxiconazole; pyraclostrobin + epoxiconazole + chlorothalonil; prothioconazole + trifloxystrobin, and iso-pyrazam + azoxystrobin, in three spray timings: GS33, GS47 and GS33+GS47, were evaluated in five field experiments. An untreated and a fully protected treatment were included. Fungicide residues, disease severity, control efficacy, area under the disease progress curve, and plump grain yield were calculated. All fungicide strategies adhered to food safety, complying with the Maximum Residue Limits established by Codex and the European Union. Effectiveness varied based on RLS development, application time, and number of applications. Fungicide treatments applied at GS33+GS47 were the most effective as the highest severity levels were observed at the stage after GS47 under the conditions studied. Plump grain yield only showed minimal differences in the late epidemic. The study emphasized the low risk of fungicide presence in grains, favoring efficacy when selecting RLS management options. Any changes in management or regulations should be carefully reviewed to maintain findings. The research underscored the compatibility of recommended fungicide treatments with food safety standards, highlighting the balance between disease control efficacy and consumer safety. .-.-.-.-.-.-.-.-.-.-.- RESUMEN.- El control de ramulariosis se realiza principalmente con fungicidas foliares, lo que puede resultar en residuos en el grano. El objetivo fue evaluar la eficacia del manejo de fungicidas utilizados para el control de ramulariosis y sus residuos en grano de cebada. Se evaluaron cuatro mezclas de fungicidas: fluxapyroxad + piraclostrobina + epoxiconazol, piraclostrobina + epoxiconazol + clorotalonil, prothioconazol + trifloxistrobina, e isopyrazam + azoxistrobina, en tres momentos de aplicación: GS33, GS47 y GS33+GS47, en cinco experimentos de campo. Se incluyó un testigo sin aplicación y un tratamiento protegido. Se determinaron los residuos de fungicidas, la severidad de la enfermedad, la eficacia de control, el área bajo la curva de progreso de la enfermedad y el rendimiento de granos mayores a 2,5 mm. Todas las estrategias de fungicidas cumplieron con los límites máximos de residuos establecidos por el Codex y la Unión Europea. La efectividad de control varió según el desarrollo de ramulariosis, el momento de aplicación y el número de aplicaciones. Los tratamientos con fungicidas aplicados en GS33+GS47 fueron los más efectivos, ya que los mayores niveles de severidad se observaron en las etapas posteriores a GS47 bajo las condiciones estudiadas. El rendimiento de granos mayores a 2,5 mm solo mostró diferencias mínimas en la epidemia tardía.
