Focusing on a specific vineyard in the Chateauneuf-du-Pape region in the Southern part of France, plant pathologists spent 8 years monitoring more than 60 plants for signs of Grapevine Pinot gris virus (GPGV). Contrary to previous observations in Italy, they observed an explosive propagation of the virus, with more than 75 percent of tested plants becoming infected between 2014 and 2015. Surprisingly, only a marginal number of grapevines tested positive during the remaining five years of the study.
