Liquorice extract as an alternative to reduce copper use in grapevines (RELACS Practice Abstract)
Copper is the only effective fungicide authorised for a variety of important uses in organic farming. Because of its environmental impact, it is restricted to 28 kg/ha over seven years in the EU, and further restrictions may come while only a few alternatives are available on the market.
Solution
As soon as the formulated Liquorice extract is authorised under EU regulation 1107/2009 and registered as a plant protection product (PPPs), it can help to reduce or even replace copper-based products, especially in organic grape production.
