Abstract

Pythium root rot has been reported in several countries, but in Greece this disease was first detected in 2021, causing severe yield losses in a hydroponic lettuce crop. Isolations, morphological and molecular characterization, as well as pathogenicity assays identified a Pythium Cluster B2a species causing the disease in hydroponically grown lettuce. This is the first report of Pythium Cluster B2a sp. causing lettuce root rot in Greece.
