First report of Neocosmospora falciformis in Spain

In the framework of a research project, surveys were carried out in 2018 and 2019 to study soil fungal pathogens affecting cucurbit crops in Spain. Diseased melon (Cucumis melo) plants were observed in the localities of Carrizales (Elche, Alicante province) and La Punta (Valencia). Affected plants showed leaf yellowing, vascular rot at the root collar and stem base. In some cases, plant collapse and death was observed. However, the incidence of the disease in the surveyed areas was low. Laboratory analysis of symptomatic plant samples revealed the presence of Neocosmospora falciformis (=Fusarium falciforme). N. falciformis is a clinically important species (associated with infections in humans and animals), belonging to the Fusarium solani complex, which can be present in agricultural environments. There have been earlier reports of this fungus causing diseases on lima bean (Phaseolus lunatus) in Brazil, soybean (Glycine max) in the USA, and Pinus maximinoi in Colombia. This is the first time that N. falciformis is detected in Spain on C. melo.

The pest status of Neocosmospora falciformis in Spain is officially declared as: Present, only in some parts of the Member State concerned, at low prevalence.
