Cinnamon leaf extract as a natural control for postharvest papaya anthracnose

A scientific study identified Colletotrichum brevisporum as the causal agent of anthracnose in papaya, a postharvest disease that reduces fruit quality and shelf life. This infection is commonly controlled using synthetic fungicides, although their potential toxicity raises concerns for human health.

The research evaluated a natural alternative based on cinnamon leaf extract (Cinnamomum burmanii) to control fungal development both in vitro and in vivo. Molecular analysis confirmed the pathogen identity through DNA sequencing, while microscopic observations showed that the extract disrupts fungal hyphal structure and inhibits growth.

Results demonstrated that different extract concentrations exhibit antifungal activity, with the 1% concentration achieving up to 74.49% inhibition of lesion development in papaya fruit. This highlights its potential as an alternative to conventional chemical fungicides.

The study concludes that plant-based extracts could be used in biofungicidal formulations or natural coatings to improve postharvest preservation of tropical fruits and reduce losses along the food supply chain.
