Botrytis Cinerea (Bud Rot) In Cannabis Growing

Botrytis cinerea is a common fungal pathogen that can affect various plants, including cannabis. It is commonly referred to as “gray mold” or “bud rot” and can have devastating effects on cannabis crops. The fungus thrives in cool and damp conditions, making it particularly problematic for cannabis plants grown in greenhouses or outdoor settings with high humidity levels.

Botrytis cinerea infects cannabis plants by entering through wounds, such as those caused by pruning, or through the plant’s natural openings, such as the stomata. Once inside the plant, the fungus spreads quickly, breaking down plant tissue and causing the characteristic gray mold that can cover the buds, leaves, and stems of the plant. This can lead to significant yield loss, as affected buds often become unusable and must be discarded.

In addition to reducing the quality and yield of cannabis crops, Botrytis cinerea can also have serious health implications for consumers. The fungus can produce mycotoxins, which can be harmful if ingested, particularly in individuals with weakened immune systems.

Preventing and controlling Botrytis cinerea in cannabis cultivation requires a multi-faceted approach. This can include maintaining proper environmental conditions, such as controlling humidity levels and improving air circulation, as well as implementing strict sanitation measures to prevent the spread of the fungus. Many growers also use fungicides and other treatments to control the spread of the fungus, although care must be taken to avoid using harmful chemicals that could impact the quality of the final product.

Overall, managing the risks of Botrytis cinerea is an important part of cannabis cultivation, and growers must remain vigilant to ensure their crops remain healthy and free from infection.
