    Grapevine pruning is a crucial cultural practice which allows to regulate/control the number of winter buds per vines/hectare and the associated yield.

    Pruning can be done by hand with a scissor (electric or none electric scissor) or mechanically (mechanical pruning)

    No pruning (called Minimal Pruning) involves to install a cordon over three years and the associated spurs and after that period not to prune anymore the vines.

    To be able to properly prune by hand, training courses are recommended as some rules have to be carefully respected and applied to limit the necrosis of the conducting tissues of the arms and spurs, allowing to avoid vine dieback and leading to a better sustainability of the vineyards (joined figure).

    To avoid/limit wood/conducting tissue necrosis at the arm and spur levels, the following recommendations are provided :

    1. To position the pruning wounds always on the same side of the arm

    2. The Simonit & Sirch method for Cordon pruning will lead over years to an increase in the height of the spurs, and it is a good thing because it will increase the wood quantity/arm and improve fruit zone microclimate!

    3. At the spur level it is recommended to alternate the pruning wounds, which will allow to increase vertically the height of the spurs

    4. Simplified and severe pruning regime should be proscribed in the framework of the prevention and management of ESCA (https://lnkd.in/dkmUbR62)
