| description | Calibrachoa hybrida (calibrachoa, million bells) is a flowering ornamental with increasing importance due to the existence of many successful cultivars for growing indoors in containers and planting in the garden and landscape. The outstanding characteristic is a profuse flowering and intense colour. In October 2019, a fungal isolate was obtained from basal calibrachoa leaves with irregular brown leaf spots, in plants cultivated in Buenos Aires, Argentina. The aim of the present study was to identify the cause of the disease in this ornamental genus, to expand knowledge about prevalent pathologies. The isolate was identified using morphological and molecular markers, and the pathogenicity tests were fulfilled. This paper reports that Nigrospora oryzae is pathogenic to calibrachoa, which seems to be the first record of this leaf spot disease in the world. |

The outstanding characteristic is a profuse flowering and intense colour. In October 2019, a fungal isolate was obtained from basal calibrachoa leaves with irregular brown leaf spots, in plants cultivated in Buenos Aires, Argentina. The aim of the present study was to identify the cause of the disease in this ornamental genus, to expand knowledge about prevalent pathologies.

Calibrachoa hybrida (calibrachoa ou falsa-petúnia) é uma planta ornamental com importância crescente no mercado devido a existência de inúmeras variedades que podem ser cultivadas em vasos, jardins e paisagismo. A característica marcante é sua floração abundante e de cores vibrantes. Em outubro de 2019, foi obtido um isolado de fungo em folhas basais de calibrachoa, com manchas foliares marrons e irregulares, em plantas cultivadas em Buenos Aires, Argentina. O objetivo do presente estudo foi identificar o agente causal das manchas foliares em calibrachoa para expandir o conhecimento sobre as doenças prevalentes nesta importante planta ornamental. O isolado foi identificado por meio de marcadores morfológicos e moleculares, bem como a sua patogenicidade foi comprovada por meio do postulado de Koch. O fungo foi identificado como Nigrospora oryzae, sendo que presente artigo, além de relatar a sua patogenicidade, parece ser o primeiro registro desta doença em calibrachoa no mundo.
