Tree Disease Treatment

Professional tree disease treatment from North Eastern Tree Care

Protecting your trees from disease begins with an extensive inspection of your landscape by one of our ISA certified arborists.  From this inspection your arborist will determine the health of your landscape, identify site-specific plant stressors and recommend appropriate tree disease treatment designed to improve the health of your trees enabling them to ward off disease naturally.

Unique Solutions

The recommendations we provide are specific to your plants needs. Tree disease treatments are designed to enhance the health and beauty of your trees and are tailored to the conditions unique to your landscape. Effective treatment for tree disease requires accurate identification of host plant and disease as well as desired results.

Many common plant diseases are caused by fungi that flourish in warm wet weather typical to the start of the growing season, others thrive during hot humid weather normally seen later in the summer. Accurate diagnosis and well-timed tree disease control plan will help prevent the production and spread of disease-causing fungi.

Common Diseases

Infectious diseases like Boxwood blight, bark canker, Phytophthora root rot and others are caused by pathogens in the form of bacteria, fungi or viruses.  Most common plant diseases are contracted by plants that are vulnerable often due to stress or damage.  For a disease to develop there must be a pathogen, a susceptible host plant and environmental conditions conducive to pathogen spread. Improving and maintaining plant health in an environment unsuitable for the spread of disease will reduce the risk of outbreak in your landscape.  

Many diseases can be identified by the symptoms present on their host plant.  Our certified arborists have an extensive knowledge of tree disease and their damaging effects which is essential for the accurate diagnosis and prescription of treatment.  We maintain a holistic viewpoint with treatment protocol knowing that disease will typically appear only when conditions allow.  Our arborists often recommend simple alterations to your landscape that can have positive effects on the health of your trees.

Fruit Tree Disease

Fruit trees in our region, including Apple, Cherry, Plum, Nectarine, Peach and Pear play host to a wide variety of diseases including leaf-spot, scab, rust and blight which will damage leaves and twigs as well as fruit.  Diseases vary by host and life cycle but treatment protocols are often similar and our methods of care are supported by leading university research which focuses on increasing results while reducing the volume of treatments necessary.

Cedar Apple Rust
Cedar Apple Rust is a tree disease that goes by two host names because it requires the presence of two very different tree species in order to persist in the landscape.  Gymnosporangium juniperi-virginianae more commonly referred to as “rust” lives by developing holiday ornament like galls with bright orange spore horns on Eastern Red Cedar trees in early spring which release teliospores that travel by wind the Apple and Crabapple trees during bud-break and leaf-expansion infecting the foliage with disease which is then passed back to the Cedar tree in late summer once it has matured on the second host plant.

Phyotphthora Bleeding Canker

Phyotphthora Bleeding Canker is a plant damaging water mold that thrives in wet soils which promotes the production and spread of spores.  Rainwater and irrigation splashes spores onto the lower trunk and branches where infections establish in cracks in the outer bark.  Since bleeding canker varieties of Phytophthora originate from the soil this pathogen might be causing root disease too.

The most common host of bleeding canker  disease in our region is European beech (Fagus sylvatica). Additional hosts all of which are common elements in landscapes include maple (Acer), American beech (F. grandifolia), birch (Betula), magnolia (Magnolia), dogwood (Cornus), oak (Quercus), horsechestnut (Aesculus hippocastanum) and walnut (Juglans).

Once established Phytophthora kills the bark and sapwood of trees and shrubs by consuming the sugars available in those layers of the plants vascular system.  This plant diseases presence can be seen in prominent bark wounds called bleeding cankers which ooze a dark amber/brown to black sap.  This disease is capable of spreading by moving withinin the host plants sap flow creating cankers higher up on the trunk and scaffold limbs over time.

Black Knot Disease
Black Knot disease was first discovered in our region around 200 years ago and continues to be destructive to valuable landscape trees including Cherry, Plum, Apricot and Chokecherry.  Unlike most common tree diseases black knot forms only on woody parts of the tree, establishing on twigs and spreading to branches and even the trunk.  Just as it sounds the disease forms rough, black growths that encircle the infested tree parts interrupting the vascular flow which kills the tree part.  The knots that remain in the tree continue the spread of disease to host plants in the landscape and serve as a home to insect pests.  It has been found that older knots can kill trees by promoting insect infestation broadening the scope of host plant material and complicating the protocol for control.  Our experienced arborists can determine the age and extent of infection/infestation and provide treatments effective for your tree and its surroundings.

Needle Cast Disease
Needle Cast Disease is a group of several different species of fungi that collectively cause damage to nearly all types of large evergreen tree that grow in our region including Colorado blue spruce (Picea pungens), white spruce (P. glauca), Oriental spruce (P. orientalis), Norway spruce (P. abies) and red spruce (P. rubens), fir (Abies), pine (Pinus), hemlock (Tsuga), Douglas-fir (Pseudotsuga) and true cedar (Cedrus).   It’s a fitting name for the disease as infection causes the tree to “cast-off” its older needles until only the newest needles at the tips of the branches remain.  Severely infected trees become unsightly, appear to be dying and may take years of treatment to fully recover, however when found early treatments are effective at preserving existing needles and provide protection for the tree moving forward.  Proper diagnosis can be easily mistaken by an untrained eye because newly infected needles often take on a purple or yellow color which mimic other potential non-disease related symptoms. http://northeasterntreecare-ny.com/tree-disease-treatment/ Let us help you with Needle Cast Disease through our tree disease treatment options
