Episode Details

To understand fungicide resistance in the vineyard, a group of United States scientists formed the Fungicide Resistance Assessment Mitigation and Extension (FRAME). Sarah Lowder, Assistant Professor and Viticulture Extension Specialist at the University of Georgia describes a nationwide sampling project to test for resistance markers. To get samples, they are promoting a new collection method called glove sampling. This process leverages the time that fieldworkers are in the field running their hands through the vines. They collect samples by rubbing their gloved hands on a cotton swab and sending the sample to the lab. Research shows that glove sampling results are very similar to spore trapping, a process that samples the air flowing through the vineyard.
