The paper monitors 199 plots of disease-resistant grapevine varieties over 8 years, showing reduced fungicide use with maintained disease control, but also resistance decline and emerging black rot issues.

The paper identifies a Plasmopara viticola strain from Reunion Island that breaks down three grapevine resistance loci, Rpv1, Rpv3.1, and Rpv10, through genomic and pathogenicity analyses.

The paper reports the breakdown of Rpv1 and Rpv3.1 resistance in grapevine due to virulent Plasmopara viticola isolates overcoming both resistance genes in multiple vineyards.

This study evaluates strategies for deploying disease-resistant grapevine cultivars and fungicide use to balance disease control, resistance durability, and economic outcomes in vineyards.
