We unfortunately identified crown gall – Agrobacterium vitis – in our Chambourcin vines. We will manage the diseased vines for production for the time being – the disease is systemic and the vines cannot be cured. Crown gall symptoms occur when an infected vine is winter injured, giving the galls a chance to form. We will train up new trunks and manage multiple trunks of different ages to manage the vineyard.
