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.
In Northern Michigan, American kestrels help cherry growers by scaring off fruit-eating birds. This reduces crop contamination and improves food safety. A low-cost, eco-friendly solution that supports sustainable agriculture and protects harvests.
Many growers rely on pressure bomb measurements or crop coefficients provided by local UCCE offices to determine their crops' irrigation needs. New technologies for modeling or remote sensing of evapotranspiration estimates are emerging to help manage irrigation.
The new protocol opens China to South African cherries from the 2026/27 season. With 819 hectares planted, rising exports and a 2-3 week window before Chilean peak volumes, South Africa is targeting zero-tariff access, new investment and a stronger presence across Asia.
In 2026, cherry production in the Yakima Valley and the U.S. Northwest is heading toward 17 million boxes. Lower volumes, firmer prices and solid demand support growers, while Rainier cherries face losses from spring frost, wind and rain. The market remains resilient.
