Marssonina coronaria, new causal agent of leaf spots in apple trees with low chilling requirements in central Argentina .
During 2017-2018 years, a fungal disease caused signifi cant early defoliation on cvs `Caricia,`Princesa ́ and `Eva ́ apples trees in the center-east of the Province of Santa Fe. The symptomatology was consistent with that reported for Marssonina spp. With the purpose of characterizing the etiology...

Marssonina coronaria defoliation low-chilling apple Santa Fe Marssonina coronaria defoliación Manzanos de bajo requerimiento de frío Santa Fe During 2017-2018 years, a fungal disease caused signifi cant early defoliation on cvs `Caricia,`Princesa ́ and `Eva ́ apples trees in the center-east of the Province of Santa Fe. The symptomatology was consistent with that reported for Marssonina spp. With the purpose of characterizing the etiology of the disease, 9 isolates were obtained; being 4 characterized morphometrically and molecularly. After 60 days, the colonies reached 10 mm in diameter, with irregular margins and brown coloration. Conidia were hyaline, slightly curved, obovoid, unequally two-celled. The size was 15.23 ± 1.49 μm x 5.47 ± 0.52 μm. The isolates were identifi ed with 100% identity as Marssonina coronaria based on ITS gene phylogenetic analyses. The pathogenicity of the isolates was confi rmed. All inoculations produced symptoms and the pathogen was re-isolated, corresponding its characteristics with those initially mentioned. This study is the fi rst report of M. coronaria affecting apple leaves in Argentina and provides useful information to design management strategies. Durante los años 2017-2018, una enfermedad fúngica causó una importante defoliación temprana en manzanos de los cvs `Caricia ́, `Princesa ́ y `Eva ́ del centro-este de la Provincia de Santa Fe. La sintomatología fue coincidente con la reportada para Marssonina spp. Con el objetivo de caracterizar la etiología de la enfermedad se obtuvieron 9 aislados, siendo 4 caracterizados morfométrica y molecularmente. Luego de 60 días, las colonias alcanzaron 10 mm de diámetro, con márgenes irregulares y coloración marrón. Los conidios, hialinos, ligeramente curvos, ovoides y bi-celulares midieron 15,23 ± 1,49 μm de largo y 5,47 ± 0,52 μm de ancho. Las secuencias de ITS indicaron 100% de identidad con Marssonina coronaria. Se confi rmó la patogenicidad de los aislados. Todas las inoculaciones produjeron síntomas y el patógeno fue re-aislado coincidiendo sus características con las inicialmente mencionadas. Este estudio constituye el primer reporte de M. coronaria afectando hojas de manzano en Argentina y proporciona información útil para diseñar estrategias de manejo.
