The Biological choice for organic farming
The biofungicide potassium hydrogen carbonate
With more and more people living on the planet, increasing global food demand is one of the biggest challenges of the coming decades. Evonik Functional Solutions' potassium derivatives contribute to sustainable, residue-free food security by enabling production with biological fungicides that are harmless to bees and other insects.
Potassium hydrogen carbonate, also known as potassium bicarbonate is used as a biological, residue-free fungicide in fruit growing, vegetable growing, viticulture, as well as for ornamental plants. The product protects plants and soil, harming the fungus.
The EU came to an agreement to focus on more environmental protection in agriculture. We're already supporting these goals.
In agriculture, potassium hydrogen carbonate is used also as a fertilizer to supplement the supply of nutrients for the crops grown and thus support the healthy growth of the plants. This results in higher crop yields and increases the quality of the yields. The soil also benefits from potassium fertilizer, which protects insects like bees and plants. Measures to combat bee mortality are particularly important because bees secure a large part of plant food through their pollination behavior.
Potassium hydrogen carbonate acts as a fungicide with preventive activity against various fungal pathogens such as gloeosporium, bortrytis or powdery mildew.
Potassium hydrogen carbonate is used against the following plant diseases.
