Pseudomonas marginalis is a soil-dwelling bacterium in the family Pseudomonadaceae, originally described in 1918 and formally named by Stevens in 1925, that causes soft rot in plant tissue. It infects a range of crop and ornamental species, including poinsettia, lettuce and crucifers such as canola and mustard, and produces the characteristic breakdown seen in soft-rotted chicory and similar vegetables. Based on 16S rRNA sequence analysis the species has been placed within the Pseudomonas fluorescens group, and it is divided into three recognized pathovars: alfalfae, marginalis and pastinacae.

Caused By Agent Kind
Entity-backed identity for the agent-kind enum value this pest or disease already carries, resolved to an agriculture concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The agent-kind fact itself stays on the pest or disease unchanged.
