We characterized Plasmopara viticola populations utilizing PCRRFLP technique to detect a point mutation known to cause resistance to carboxylic acid amides (CAA) fungicides. Sensitivity of these samples to the mandipropamid fungicide was assayed by a leaf-disc method. In this work, we provide the first evidence about the presence of mandipropamid-resistant populations of P. viticola from commercial vineyards in Italy. Improving the knowledge about development of resistant populations could enhance the current grapevine downy mildew management strategies and minimize the risk of the spread of mandipropamid and other CAA-resistant populations.

Abstract
We characterized Plasmopara viticola populations utilizing PCRRFLP technique to detect a point mutation known to cause resistance to carboxylic acid amides (CAA) fungicides. Sensitivity of these samples to the mandipropamid fungicide was assayed by a leaf-disc method. In this work, we provide the first evidence about the presence of mandipropamid-resistant populations of P. viticola from commercial vineyards in Italy. Improving the knowledge about development of resistant populations could enhance the current grapevine downy mildew management strategies and minimize the risk of the spread of mandipropamid and other CAA-resistant populations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
