Relationships between vine vigour and the incidence of grey mold and powdery mildew in Aranel grapevine

Abstract

The extensive use of pesticide products for protecting grapevine against pathogens such as grey mold and powdery mildew can result in the pollution of superficial and subterranean waters, To face this problerm, integrated pest management systems have been developped in vineyards. They are generally based on epidemiological models (1) and of\on observations of attacks in the vineyard. However, they do not take into account the state of the canopy, i.e. its growth and architecture. Nevertheless, vinegrowers and pathologists recognise the importance of the relationships between vine vegetative vigour and sensitivity to fungi attacks (2) although these relations are poorly documented in the litterature. For example, experiments carried out in France on grapevine cv Chenin showed a high positive correlation between Botrytis cinerea symptoms and vine vigour (expressed as weight of pruned canes) (3). In this context, the objective of this study was to investigate the possible positive relationship between grapevine vigour and the final level of grey mold and powdery mildew
