Botryosphaeria stevensii, also known as apple sphaeropsis, is a fungal plant pathogen that causes cankers and branch dieback, in severe cases affecting a large portion of a tree's canopy and killing entire plants. Its original host is apple, on which it was first described from fallen fruit in Great Britain in 1836, and it also affects junipers, including Rocky Mountain juniper, eastern redcedar and Chinese juniper, as well as grapevines. Management relies on resistant cultivars, well-draining soil, adequate light and plant spacing to reduce the moisture that favors infection.

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.
