Cover crops under the vines: a viable alternative for weed management in Mediterranean vineyards
A Trifolium fragiferum (strawberry clover) cover crop was used as an alternative for weed control under the vines in an irrigated vineyard located in a semiarid area of Northern Spain. The cover crop allowed a satisfactory and ...

Late frost protection – what to retain from the Champagne experience?
With the occurrence of frost, sensitive plants are susceptible to damage. One of the most counter-intuitive impacts of climate change is the increasing frequency of spring frost. Studies have warned of this problem (Inouye, 2008), ...

Reducing possibly synthetic fungicide input by using vigor thresholded NDVI as early risk indicator of Botrytis bunch rot in vineyards
Botrytis bunch rot (BBR) is a major disease occurring in vineyards worldwide. Its control, still largely based on synthetic fungicide sprayings at pre-determined intervals, often leads to residues in grapes and wines that ...

Late pruning of the vine
In the current climatic context, with milder winters leading to earlier budburst in most wine regions, vines are exposed to the risk of spring frosts for a longer period. Depending on the year, frost can lead to yield losses of between ...

What could be the architectural forms of future vines adapted to climate change: a new challenge! Let’s discuss the Gobelet (Bush Vine)
The architectural form of a vineyard is the result of the training system (plant spacing, geometry, pruning, trellising), the vigour of the plant material (soil x climate x cultivar/rootstock) and other cultural practices implemented each ...
