Pomegranate Waste Fights “Soapy Olive” Disease in Olive Trees
A new study has found a natural way to protect olive trees from a major threat. Scientists discovered that extracts from pomegranate husks and carob leaves can help fight anthracnose, also known as “soapy olive.” This fungal disease causes greasy fruit, reduces yield, and lowers olive oil quality.
Natural Extracts Show Powerful Protection
Researchers from the University of Córdoba and the Polytechnic Institute of Bragança tested these plant-based extracts. They found that both substances slowed the fungus’s growth and prevented it from infecting olive plants. In addition, the carob extract triggered the tree’s natural defense system.The extracts, once considered agricultural waste, are now proving to be valuable. They could replace chemical fungicides and help create a greener, more sustainable olive industry. As a result, they support the shift toward an eco-friendly biocircular economy.
Sustainable Science in Action
The research team tested the extracts in controlled environments. They confirmed that carob leaf extract reduced disease cases by up to 35%. While traditional fungicides still perform better, this is a big step toward natural solutions.According to lead researcher Carlos Agustí, this discovery brings hope for sustainable disease control. However, more testing is needed in real-world conditions to confirm results and assess large-scale use.
A Greener Future for Olive Farming
This research highlights how waste products can protect crops and promote sustainability. If further studies succeed, olive farmers could soon have an eco-friendly weapon against “soapy olive.” Therefore, the humble pomegranate husk may play a surprising role in saving future olive harvests.
