The spotted lanternfly: a threat to viticulture in Europe
The spotted lanternfly (Lycorma delicatula) is an insect native to southern China and Taiwan, introduced to other parts of Asia and then to the United States. It feeds on the sap of many plants, including grapevines ...

Increasing grapevine canopy height to compensate for pre-flowering basal leaf removal
Yield loss following intensive pre-flowering leaf removal (LR) can be up to 40-50 % of initial potential. A study conducted by Agroscope on the white grapevine Petite Arvine evaluated the effects of higher hedge trimming to ...

The intravarietal diversity of sugar concentration in Merlot depends more on late evaporation than sugar loading
The rise in temperature associated with climate change can lead to excessive sugar concentrations at harvest. To maintain varietal typicity in the future, more resilient genotypes need to be identified within clonal ...

Impact of training system, soil management, and soil water holding capacity on vine water status in the Cognac production area under climate change
With climate change, the risk of water deficits in vineyards is tending to increase, potentially affecting yield and grape quality potential. In this study, the Lebon et al. (2003) soil water balance model was ...

Characterization of sugar accumulation dynamics in grapes and the factors influencing this process at local scale
Determining the sugar concentration in grape berries is essential for winegrowers, as it enables them to estimate the alcohol content in the final wine and optimize the harvest date. In the face of climate change and rising ...

Respectful pruning in young vineyards: impact on growth and potential implications
In recent years, there has been a resurgence of interest in grapevine pruning. This growing focus has emerged as a response to the long-term issues that poor pruning practices have caused in vineyards. Decades of ...

Improving the success rate of dead vine replacement
Dead vine replacement can be a very costly exercise in the event of failure, especially given that replacement vines take longer to reach full production than young plants from a completely replanted plot. Success, ...

A meta-analysis of the ecological impacts of viticultural practices on soil biodiversity
Soil quality and adequate soil management are key levers for sustainable viticulture. Until now, a global and comprehensive analysis of the impact of viticultural practices on soil biodiversity was lacking. We conducted a ...

Impact assessment of cover crops on the risk of frost in the Anjou vineyard
The increase in the frequency of spring frosts and the rising precocity of the phenological stages of the vine have been threatening the wine production in the Anjou vineyard for several years (Petitjean et al., 2022). In addition to ...

Part 1: Is there a correlation between the diameter of the pruning wound and the length of the desiccation cone?
While pruning is an age-old and essential practice for managing yields and keeping vines in production for as long as possible, many questions remain unanswered about its role in vine physiology, particularly with regard to the formation of ...

Part 2: How long to form the desiccation cones of the chicot and when should be removed the chicot?
Leaving a chicot when pruning is now a widespread practice in vineyards, but the question remains as to when this zone of dead wood can be “re-pruned”. Can it be removed the year after pruning? Should you wait for a full ...

Wrapping permanent cordon arms tightly around the cordon wire negatively impacts vine performance
In certain winegrowing regions, it is a common practice to wrap canes very tightly around the cordon wire during the establishment of permanent cordon arms. This method of training may result in a constriction of the ...
