What it is / How it shows up:
Fusarium is often mentioned in cannabis cultivation contexts, especially regarding plant health issues seen in store menus or farming reviews. It's a soil-borne fungus that attacks the vascular system of cannabis plants, blocking water and nutrient transport, causing leaves to wilt and eventually die. Fusarium thrives in warm, wet environments, often found in greenhouses and indoor grows. The fungus can survive in soil for years, making eradication difficult without proper management practices.
How it’s measured or identified:
- Visual inspection for wilting and yellowing leaves.
- Soil and plant tissue testing for fungal presence.
- Microscopic examination of spores.
Use in context:
- "Our crop was affected by Fusarium, leading to significant loss."
