Also called / Category:
Also known as grey mould; Category: Pests, Pathogens & Disorders.

What it is / How it shows up:
Botrytis (bud rot) is a common term found in cannabis cultivation literature and forums. It is a fungal disease that targets cannabis plants, primarily during the flowering stage. The fungus thrives in cool, damp conditions and causes the buds to turn brown and grey, eventually leading to their decay. Cultivators often discover botrytis when inspecting their plants for quality control or during routine maintenance. Recognizing the early signs of infection can save a crop, as the disease spreads quickly if left unchecked.
How it’s measured or identified:
- Visual inspection for grey or brown patches on buds.
- Checking for a musty odour emitted by infected plants.
- Monitoring humidity levels in the grow environment.
Use in context:
- "We lost a few plants to botrytis last season due to high humidity."
- "Preventing bud rot requires good air circulation and regular plant checks."
- "Botrytis can devastate a harvest if not detected early."
Safety & compliance in Canada:
- Ensure grow areas are well-ventilated to prevent fungal growth.
- Regularly inspect cannabis plants for signs of botrytis.
- Dispose of infected plants properly to prevent spread.
