Abstract

First report of Pectobacterium betavasculorum associated with bacterial vascular necrosis and root rot disease of sugar beet in Turkey.

Abstract

During June and September of 2018, bacterial necrosis and root rot disease surveys were conducted in sugar beet (Beta vulgaris) fields in Yozgat province in the Central Anatolia region of Turkey. From 33 fields surveyed, 19 sugar beet plants exhibiting vascular necrosis with blackened petioles, root rotting varying from wet to dry and wilting symptoms were collected for bacterial isolation. The causal pathogen was isolated and identified as Pectobacterium betavasculorum based on morphological and biochemical characteristics, as well as nucleotide sequence, phylogenetics and pathogenicity test. This is thought to be the first report of P. betavasculorum causing bacterial vascular necrosis and root rot disease on sugar beet in Turkey.
