Halo blight

Bacterial Diseases of Crops

Halo blight of bean is a bacterial disease caused by Pseudomonas syringae pv. phaseolicola, a gram-negative, aerobic, polar-flagellated, non-spore-forming bacterium. The disease was first identified in the early 1920s and rapidly became a major disease of beans worldwide. It is favored by moderate temperatures and conditions where plentiful bacterial inoculum is available.

Bacterium, Concepts

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.
