Sodium hydrogen carbonate / baking soda
Sodium hydrogen carbonate is a sodium salt of carbonic acid, which is also used in the production of foodstuffs. It is contained in baking powder and is therefore an integral part of almost all baked goods, cereal mixes, cakes and tarts. It is also widely used in medicine, especially to regulate stomach acidity, and is known as Bullrich salt. Sodium hydrogen carbonate is therefore completely safe for humans and the environment and has no side effects.
Around 100 years ago, a German pharmacist discovered the effect of sodium bicarbonate against powdery and downy mildew. Even back then, he used it to protect his rose bushes and fruit trees against the dreaded fungal diseases in an environmentally friendly way and without side effects. Sodium bicarbonate is dissolved in water and sprayed on the plants when dripping wet. This increases the pH value on the surface of the leaves and makes it more difficult for powdery and downy mildew fungi to adhere to the plants.
Powdery mildew fungi are among the best known and most widespread plant diseases. Powdery mildew infestation can be recognised by a powdery, whitish coating, usually on the upper side of the leaf. A small initial infestation can spread over a large area within a few days. Powdery mildew causes severe damage to plants. In crop plants, it leads to yield losses and in many cases even to the complete destruction of the harvest. On ornamental plants such as roses, the damage is characterised by pale flowers and wilted leaves.
Base substance registered in the EU Plant Protection Products Regulation In October 2015, the EU Commission authorised sodium hydrogen carbonate as a base substance in the EU Plant Protection Products Regulation (1107/2009). Since then, its use as a fungicide to combat mildew and apple scab as well as for the post-harvest treatment of storage diseases has been authorised.
Application:
For better adhesion, the sodium hydrogen carbonate should be used together with a vegetable oil - e.g. neem oil - and an emulsifier - e.g. the neem oil emulsifier "Rimulgan". This combination forms a wafer-thin coating on the leaves and thus ensures even distribution and good adhesion of the sodium hydrogen carbonate. All these substances are non-toxic to humans and their pets and their use is gentle on beneficial organisms.
Mix vegetable oil and emulsifier together to formulated oil.
Preparation of the spray mixture: Dissolve "sodium hydrogen carbonate" in water, then stir in the formulated oil. Apply dripping wet with a sprayer.
Repeat the treatment every 7 - 14 days.
Dosage per litre of spray mixture:
Roses, fruit trees, shrubs:
- 5 - 10 g sodium hydrogen carbonate
- 5 - 10 ml formulated oil
Vegetables, lettuce:
- 2.5 - 5 g sodium hydrogen carbonate
- 5 ml formulated oil
Viticulture:
- 2.5 - 5 g sodium hydrogen carbonate
- 5 ml Formulated oil

Sodium hydrogen carbonate is a salt from the food industry and therefore completely harmless to humans, animals and the environment. It is a ubiquitous raw material widely used in food, food industry, medical and hygiene products. See more about its many applications in the "Raw material info" section under NaHCO3. TIP! For better adhesion to plants we recommend the application together with neem oil & neem oil emulsifier "Rimulgan". Due to the better adhesion, the sodium hydrogen carbonate remains effective longer. You get all three products together in our practical Neem Combipack (>> to the product)! Dosage for 1 litre of water: For soft-leaved plants (cucumbers and other vegetables):2.5 ml (g) sodium hydrogen carbonate For hard-leaved plants (roses, fruit trees and shrubs, many houseplants):10 ml (g) sodium hydrogen carbonate
In addition to the three components of the “Neem Combipack", Mildew Combipack Plus also contains the plant strengthening agent "Lebermooser". By dissolving the components in water, you get a highly effective spray broth that makes a decisive contribution to keeping your plants healthy. The resistance of your plants is strengthened against powdery and downy mildew as well as against other fungal diseases and bacterioses. For easier handling, the components Neem Oil and Rimulgan are already premixed. Dosage for 1 litre of water: For soft-leaved plants (cucumbers and other vegetables):5 ml (g) Neem oil-emulsifier mixture + 2.5 ml (g) sodium hydrogen carbonate ( mildew salt) + 5 ml (g) liverwort. For hard-leaved plants (roses, fruit trees and shrubs, many houseplants):10 ml (g) neem oil-emulsifier mixture + 10 ml (g) sodium hydrogen carbonate ( mildew salt) + 5 ml (g) Lebermooser
