Eutypa dieback

Symptoms and signs: Eutypa symptoms are most obvious in early spring when shoots are one to two feet long. At this stage, shoots on affected wood appear stunted with shortened internodes. Leaves are unusually small, yellowed, cupped downwards, and will often have necrotic spots or regions (Fig. 1). Leaf margins may appear tattered. Affected shoots are often observed on only one trunk of a multiple trunk vine or one cordon of a bi-laterally trained vine. Early season symptoms become less visible as adjacent, healthy shoots grow and obscure the affected growth.
