A natural emulsion combining fengycin and essential oils can significantly inhibit the growth of the fungus Moniliophthora roreri [1, 2].
The discovery offers a potential lifeline to cocoa farmers in Latin America who face massive crop losses due to moniliasis. Because the fungus can destroy a vast portion of the harvest, a sustainable control method is critical for regional economic stability.
Moniliophthora roreri is responsible for one of the most devastating diseases affecting cocoa in the region [2]. The fungus is capable of threatening up to 80% of cocoa production [1, 2], with some estimates suggesting it can destroy between 70% and 80% of the harvest [1].
Researchers developed the innovative formulation using fengycin, which is a lipopeptide produced by bacteria of the genus Bacillus [1]. By combining this compound with essential oils, the emulsion creates a barrier that stops the fungus from proliferating.
Phys.org said a new study shows that these emulsions can effectively inhibit the growth of the pathogen [1]. This approach moves away from traditional chemical fungicides, which can have negative environmental impacts.
MSN said the formulation based on natural compounds could become a sustainable alternative for controlling moniliasis [2]. The use of biological agents like fengycin allows farmers to manage the disease without relying on synthetic chemicals that may harm the surrounding ecosystem.
Latin American cocoa producers have long struggled to find a balance between effective disease control and environmental preservation. The ability to suppress the fungus using natural emulsions could reduce the volatility of cocoa yields, and protect the livelihoods of thousands of farmers.
“The fungus is capable of threatening up to 80% of cocoa production.”
The development of a bio-based emulsion addresses a critical vulnerability in the global cocoa supply chain. By providing a sustainable method to combat Moniliophthora roreri, this innovation could stabilize cocoa prices and ensure the long-term viability of farming in Latin America, where the disease currently threatens the majority of the harvest.
