Dynamics of grapevine fanleaf virus (GFLV) infection in the vineyard and study of the response of different rootstocks

Abstract

Planting is a major step in the life of a vineyard. The choices made at this stage, including that of the plant material, commits the winegrower for several decades (Dewasme et al., 2022a). The rootstock, which forms part of the terroir, can contribute to the longevity of the vineyard. Viral diseases represent one of the major causes of dieback today, though their prevalence remains difficult to quantify (Dewasme et al., 2022c). The effects of different rootstocks on the impact of viral diseases need to be determined if they are to be used to help control dieback and extend the life of vineyards.
