Abstract
Ramularia collo-cygni is the biotic factor responsible for the disease Ramularia leaf spot (RLS) of barley (Hordeum vulgare). Despite having been described over 100 years ago and being considered a minor disease in some countries, the fungus is attracting interest in the scientific community as a result of the increasing number of recorded economically damaging disease epidemics. New reports of disease spread and fungal identification using molecular diagnostics have helped redefine RLS as a global disease. This review describes recent developments in our understanding of the biology and epidemiology of the fungus, outlines advances made in the field of the genetics of both the fungus and host, and summarizes the control strategies currently available. |

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. La investigación resaltó la compatibilidad de los tratamientos recomendados de fungicidas con los estándares de seguridad alimentaria, destacando el equilibrio entre la eficacia en el control de enfermedades y la seguridad del consumidor. -.-.-.-.-.-.-.-.-.-.- RESUMO.- Ramulariose é principalmente controlada por pulverização de fungicidas foliares, o que pode resultar em resíduos nos grãos.
