What are cannabis fungicides?
Fungicides are phytosanitary products designed to prevent or eradicate fungal infections in plants. In marijuana cultivation, fungal diseases such as powdery mildew, downy mildew, and botrytis are very common, especially in humid or poorly ventilated environments. These products help maintain crop health throughout all stages of growth.
What benefits do they provide?
A good fungicide can make the difference between a successful harvest and complete flower loss. Regular or preventative use helps:
- Keep leaves and buds free of infections.
- Prevent the spread of the fungus to the rest of the crop.
- Improve the overall health of the plant.
- Increase performance and final quality.
In addition, many modern fungicides offer natural or ecological solutions, suitable for organic cultivation, without leaving toxic residues.
Who should use fungicides?
Every grower, whether indoor or outdoor, should have at least one preventative fungicide in their arsenal. Humidity, plant density, or temperate climates can favor the growth of fungi, and quick action is key.
What types of fungicides exist?
- Preventative fungicides: such as sulfur or propolis, which strengthen the plant's resistance and prevent infections.
- Contact fungicides: eliminate the fungi present when applied directly to the affected areas.
- Systemic fungicides: penetrate the plant and protect it from the inside for several days.
- Ecological solutions: such as neem oil, horsetail extract or potassium bicarbonate.
Which ones are the most recommended?
Among the most effective are:
- Propolis: a natural solution with propolis, very effective against common fungi.
- Botryprot by Prot-Eco: specific against botrytis, ideal during flowering.
- Aptus Fungone: for foliar cleansing and prevention of fungal diseases.
- Cannacure by Canna creates a protective film over the plant.
What brands will you find?
In this category, you'll find products from leading manufacturers such as Prot-Eco, Aptus, Canna, Trabe, and Agrobacterias. All of these brands offer safe, effective, and suitable solutions for marijuana cultivation, many of which are compatible with organic farming.
Frequently Asked Questions about fungicides for cannabis
When to apply a fungicide to cannabis crops?
Ideally, preventative fungicides should be applied from growth to the beginning of flowering. In case of infection, immediate action with a contact or systemic product is key to preventing spread.
Can I use fungicides during flowering?
Yes, but with caution. It's recommended to opt for natural or organic products and avoid harsh treatments close to harvest to avoid leaving residues on the buds. In some cases, rubbing the leaves with a sponge soaked in water and fungicide will be better than spraying the buds themselves.
