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.
A good fungicide can make the difference between a successful harvest and complete flower loss. Regular or preventative use helps:
In addition, many modern fungicides offer natural or ecological solutions, suitable for organic cultivation, without leaving toxic residues.
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.
Among the most effective are:
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.
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.
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.
