Sodium hydrogen carbonate

Sodium hydrogen carbonate, commonly known as baking soda, is classified as a low-risk active substance used primarily as a fungicide in modern agriculture. Due to its minimal impact on the environment and human health, it is a preferred choice for sustainable and organic cultivation practices.

The mechanism of action for this substance involves the disruption of the fungal cell membrane integrity and the osmotic balance of the spores. By increasing the pH on the plant's surface, it creates an alkaline environment that is detrimental to the survival of common fungal pathogens, effectively preventing spore germination and mycelium development.

It is mainly employed to control powdery mildew on a wide variety of crops, such as cucumbers, grapes, strawberries, and ornamental flowers. The treatment acts strictly through physical and chemical contact, making it an excellent prophylactic measure to inhibit the spread of fungal diseases in the field or greenhouse.

When applying, it is critical to pay attention to dosage to avoid phytotoxicity, specifically leaf burn. It is advised to perform applications during early mornings or late evenings when solar radiation is low. Since it is a contact fungicide, full coverage of both leaf surfaces is necessary to ensure the effectiveness of the treatment.

• Preventive application before severe infestation.
• Frequent application cycles to maintain protection.
• Use of surfactants to improve adherence to plant foliage.
• Compatibility check when mixing with other organic treatments.

Sodium hydrogen carbonate provides a residue-free solution, meaning there is no pre-harvest interval required, which is a major advantage for vegetable and fruit producers. As an eco-friendly tool, it does not contaminate groundwater or harm beneficial insects, making it a cornerstone of integrated pest and disease management programs.
