First report of Stenocarpella maydis in Spain
Stenocarpella maydis (EPPO A2 List) is first reported from Spain. Scattered maize (Zea mays) plants with symptoms of premature wilting and leaf senescence were observed in one commercial field in Torres de Alcanadre (province of Huesca, Aragon) during the summer of 2012. Similar symptoms including disintegrated stalk pith tissues, and lodged plants following rain and strong wind were observed again in two commercial fields in Almacelles (province of Lleida, Catalonia) in 2016 and in two commercial fields in Biota (province of Zaragoza, Aragon) in 2017. Estimated disease incidence ranged from 15 to 30% depending on the field. Symptomatic plants were collected from the fields in Almacelles and in Biota, and Stenocarpella maydis was identified based on morphology and sequencing.
The situation of Stenocarpella maydis can be described as: Present, few occurrences.
