New pathogen threatens fennel worldwide

A new pathogen threatens fennel crops around the world – the first fungal disease Ochraceocephala foeniculi was discovered in 2017, but now it has spread to new types of dill. This conclusion was made by biologists from the University of Catania.

A new pathogen threatens fennel crops around the world – the first fungal disease Ochraceocephala foeniculi was discovered in 2017, but now it has spread to new types of dill. This conclusion was made by biologists from the University of Catania.

An international research team led by Dalia Aiello from the University of Catania first identified the causative agent of this disease. For this, scientists collected 30 samples of fennel in the affected areas of Sicily and studied fungal colonies from symptomatic tissues.

“Species of fungi obtained from symptomatic tissues were identified on the basis of morphological features and molecular-phylogenetic analysis of the ITS-LSU-SSU rDNA matrix, which led to the description of the fennel pathogen as a new genus and species of Ochraceocephala foeniculi”.

It turned out that there are types of fennel with innate immunity to this fungus, such as Aurelio, Archimedes and Pegasus. Now scientists plan to conduct additional studies of the effect of Ochraceocephala foeniculi on fennel species and the possibility of a new selection of various types of this plant.
