First report of stalk rot of maize caused by phaeocytostroma ambiguum in the Iberian Peninsula
Maize (Zea mays L.) with symptoms of premature leaf senescence and wilting was observed in two commercial fields, in Santarem (Portugal) and Almodovar del Río (Spain), in the summer of 2014. Similar symptoms including brown lesions of lower internodes and disintegrated stalk pith tissues occurred again in two commercial fields in Almacelles and Biota (Spain) in the summers of 2016 and 2017, respectively. Depending on the field, estimated disease incidence varied between 10 and 30%. Lodging was observed on 10 to 20% of maize plants in the two commercial fields following rain and strong wind.
