Disease : the "Broussin"

We just found a branch infected with the "Broussin" It is the only bacterial desease that affects the vineyard of Champagne.

Broussin is the only desase of this category that can be found in Champagne. It's produces by a bacteria present in the all vineyard and remaining dormant until it find favourable conditions of development like after strong frosts or the lesions or burst caused by hail. Some tumors appear that destroy the vasculature and, on the young vines, cause the death of the cep. This is fortunately a rare desease appeared suddenly in Champagne ofter the big frost of the winter 1978. The remedy is essentialy to remove and burn the diseased branchs. By chance, the pruning is a meticulous and manual work, so it's impossible not too see any branch contaminated by the Broussin, so is destruction is systématic.
