Globisporangium splendens is a damaging root pathogen with a broad host range, favored by warm, wet conditions. It is particularly problematic in greenhouses and irrigated fields, where it can spread rapidly and cause significant losses if not properly managed. It spreads through infested soil, water, tools, and infected plant debris. Seed is not known to be a pathway for any host.
