Boxwood is a shrub or small tree that is grown most often for decorative purposes. Like any other type of plant, must Buchsbaum of diseases, insects, invasive weeds and other threats that can be protected to threaten their health and longevity. Among the most common potentially fatal diseases of boxwood is Volutella leaf and stem blight. Exercise effective control measures can succumb to protect your boxwood this disease.
Volutella Leaf and Stem Blight
The fungus Pseudonectria rouselliana in its imperfect stage Volutella known buxi, causing leaf and stem blight Volutella, current research shows that the same fungus can also be associated with cancer and wilt diseases in boxwood. Unhealthy or neglected boxwood are likely to be infected than healthy specimens. If branches, leaves and other foliage from an infected boxwood fall to the ground and can not be removed, the disease can spread to neighboring Boxwood when the fungus produces spores means.
Just before new growth begins in the spring, leaves on infected boxwood turn upwards and inwards towards the bush and see a bright orange or bronze color, which eventually turn into a tan. Twigs and small branches die and fall. If the fungus sporulated, and produces spores, breaking pink and cream wounds over the boxwood leaves and twigs. Dark brown or black crabs are also visible under the bark of the tree book.
Good hygiene is the first line of defense against Volutella leaf and stem blight. If infection is detected first, prune away infected branches and twigs at least 4 inches above the diseased tissue and discard the prunings immediately. Prune the tree book thoroughly to allow proper air circulation and sunlight, contributing to poor levels of either fungal infection. In cases of extreme infection fungicidal treatment may be necessary. Note that a fungicide. Not cure the disease in an infected boxwood, but infections prevented in future generations
The symptoms of winter injury closely in a boxwood which Volutella blade and shaft are similar blight, a tree that suffers from winter injury can easily be mistaken for one infected with the disease, to coincide the two can, in winter injuries often a plant leaves vulnerable for fungal infections. If you notice any of the symptoms described above, wait until the next growth season, to see if new leaves instead of fading, tan ones grow. If so, the culprit was just winter injury and you have to allow the tree to recover on its own. If no new leaves appear Volutella leaf and stem blight is the most likely cause, and immediate action is required to protect your boxwood.
