Germany is launching an initiative in the EU Agricultural Council to secure the use of sodium bicarbonate – the main component of baking powder – in viticulture. The substance has been successfully used against powdery mildew for years. It is considered cost-effective, readily available, and environmentally harmless. Apparently, if a product is approved for agricultural use in the EU, none of its ingredients can be approved for use on their own. Balderdash! We'll have to apply baking soda or baking powder, whichever is correct, next year.
Germany is also seeking EU approval for the use of potassium phosphonate (or phosphate) as an alternative to copper-based fungicides. Looks like we'll have to try that, too.
