Desuckering is an operation carried out during the vine's growth period that consists of eliminating not buds, but shoots that form on the old wood. This practice has several benefits, in both phytosanitary and technical terms.
-
Phytosanitary: this procedure reduces the accumulation of vegetation around the trunk and combats fungal diseases (downy mildew) and the proliferation of certain insect vectors of flavescence dorée (Scaphoideus titanus) in a prophylactic (preventive) manner.
-
Technical: pruning reduces competition with the vine. Because the shoots are herbaceous, they consume energy and represent a sap well for the vine which is not always desirable, especially if the vine is not particularly vigorous. This technique also allows aeration around the vine and facilitates the passage of agricultural machinery.
