dc.descriptionA vineyard in south-central Chile was surveyed during five growing seasons to analyze the increase over time in the number of plants infected with Grapevine leafroll-associated virus-1, -2 and -3. At the end of the study, GLRaV-3 was found to be the most prevalent virus, with 46% of plants infected by this pathogen. GLRaV-2 infected 13% of plants, and GLRaV-1 infected 12%. Considering all three viruses together, the prevalence of infection increased exponentially from 14% of the plants at the beginning of the study period to 68% at the end. The patterns of the spread of GLRaV-2 and GLRaV-3 were mostly along the rows, whereas the pattern of spread for GLRaV-1 could not be determined.Un viñedo de la zona centro – sur de Chile fue monitoreado durante cinco temporadas con el objetivo de analizar el desarrollo de la epidemia de Grapevine leafroll-associated virus -1, 2, y 3. Al final del tiempo de evaluación el GLRaV-3 resultó ser el virus más prevalente con un 46% seguido del GLRaV-2 con 13% y GLRaV-1 con 12%. Considerando los virus en su conjunto, la infección avanzó rápidamente de un 14% inicial de plantas afectadas a un 68% al final del período. El patrón de diseminación de la epidemia fue fundamentalmente en el sentido de la hileras del viñedo para los virus GLRaV-2, y -3, mientras que para GLRaV-1 no pudo ser determinado.en-US
