Grapevine powdery mildew can be costly and devastating to fruit quality and grapevine health. Effective management is key, but what happens if your fungicides do not work as well as they should? New research may hold the answer.
A national research and extension effort to understand and reduce the impact of fungicide resistance in grapevine powdery mildew was launched in 2018 by a multi-regional team of scientists and extension educators. Dr. Michelle Moyer (Washington State University) leads the four-year, $4.75 million project funded through the U.S. Department of Agriculture’s Specialty Crop Research Initiative (SCRI). The grant received the first installment of $2.4 million in September 2018 for the initial two years of the four-year project.
The project, titled “Fungicide Resistance Assessment, Mitigation and Extension Network for Wine, Table and Raisin Grapes,” is dubbed the FRAME Network for short. The FRAME project expands on research of powdery mildew fungicide resistance underway in Washington, Oregon and California. That research, supported by the Washington State Wine Commission, the Oregon Wine Board and the American Vineyard Foundation, totals about
$600,000, and helped to leverage the $4.75 million project.
