Spotted Wing Drosophila, a well-known pest that infests ripe, ready-to-eat fruit, poses a significant threat to farmers because it is very difficult to control with standard pesticides. A new approach to tackling this pest involves manipulating the behavior of these insects by disguising healthy fruit as if it were infected with an unappealing pathogen.
By studying the specific odors emitted by infected fruit, researchers have identified the chemicals that repel the flies when applied to healthy fruit and are developing a slow-release device to disperse these fruity odors in the field, ensuring that they do not come into direct contact with the fruit. This method provides a new tool to help farmers protect their crops without relying exclusively on insecticides.
The cherries of Los Antiguos, grown in the heart of Argentine Patagonia, have earned PDO status thanks to a unique microclimate, time-honored farming techniques, and a long collective effort that highlights their quality, sweetness, crunch, sustainability, and export potential.
Pathogenicity tests showed that all isolated species could cause fruit infections, though with varying levels of aggressiveness. Among them, Diaporthe eres displayed the highest virulence followed by Fusarium incarnatum and Botryosphaeria dothidea.
A Chinese study shows the effectiveness of 5-aminolevulinic acid hydrochloride against sweet cherry black rot, inhibiting Alternaria alternata and improving postharvest fruit quality. An innovative strategy for food safety and sustainable crop protection.
Post-harvest sweet cherry management is a key phase for reserve accumulation, flower bud differentiation and future yield. In Chile, summer pruning, irrigation, nutrition and stress control influence vegetative balance, fruit quality and long-term orchard performance.
