Oregano essential oil can effectively prevent blue mold rot in pears without compromising fruit quality. The oil works by damaging the fungal cell membrane, causing it to leak and die. Additionally, the treatment helps pears stay fresher longer by reducing water loss and maintaining firmness, while naturally boosting the fruit’s own defense systems against damage.
Researchers tested essential oils from two Chilean herbs, Aloysia citriodora and Aloysia polystachya, against fungi that cause fruit rot after harvest. They found that oil from Aloysia citriodora, especially a compound called farnesol, effectively killed the disease-causing fungi in laboratory tests. These natural oils could replace synthetic fungicides that are becoming less effective and harmful to the environment, offering farmers a safer way to protect their fruit during storage and transport.
Avocados are a valuable global fruit crop, but two fungal diseases—anthracnose and stem-end rot—cause major economic losses by making fruit unmarketable. These fungi infect avocados in the orchard but remain hidden until the fruit ripens, making them difficult to detect and control. Recent advances in detection technology and disease management strategies, including biological controls and natural treatments, offer promising solutions to reduce losses and keep avocados fresh from farm to table.
Researchers found that treating sweet cherries with phenyllactic acid (PLA), a natural organic acid, can significantly extend their shelf life while keeping them fresh and flavorful. A treatment with 8 mmol·L⁻¹ PLA concentration worked best, reducing decay, maintaining firmness and sweetness, and improving the fruit’s natural antioxidant properties during cold storage. This natural preservative approach offers a safe alternative to chemical fungicides while preserving the delicious taste and nutritional quality that consumers value in cherries.
