Yellowing and later on Browning of shoots, twigs and branches; loss of leaves, death of parts of the plant. Black, small, dot-like fruiting bodies emerge from the bark of dead twigs and branches (hand lens!).

Impact

Common disease of Cupressaceae, especially of Thuja, Port Orford Cedar and Juniper; infetions are favoured by various weakening factors as for instance nutrient deficiencies.

A chemical treatment is mostly not necessary. At first, the cause of the weakening preceding the infection should be identified and subsequently eliminated ; infested material should be removed.
