| Analysis - view details of type of pest/disease/disorder | |
| Symptoms | Damping off of seedlings: base of stems shrivels due to girdling, plant bending downwards; older plants: leaf-scales turn yellow, then brown, finally they drop; on shoots, twigs, branches and stems lentil-shaped to stripe-shaped sunken lesions develop. As a consequence, parts of the plant or the whole plant dries out. | |
| Impact | Common weak parasite of Cupressaceae; various weakening factors as heat (seedlings!), stand density, wet stands or root damage may lead to Pestalotiopsis-infections. | |
| Control | Curative control not effective; avoidance of weakening factors | |
| Hosts | Thuja; Leyland cypress; False Cypress; Juniper; | |
| Affected plant parts | Needle; Shoot/Twig/Branch; Stem; |
