Tree/Shrub Disease Treatment

We provide disease control programs designed to maximize health and vigor, while taking into account the individual condition of the trees and shrubs at your home or business. Tree and shrub services are most effective when the species, disease characteristics, and customer objectives are all taken into account.

Foliar disease applications are designed to protect your valuable evergreen and deciduous ornamentals from damage resulting from tree diseases. Most of these are caused by fungi that are prevalent during spring when the weather is rainy. Treatments provide a protective barrier on the leaf or needle surface that will prevent the germination and growth of spores that cause tree diseases.

Common tree Diseases in the greater Washington area include:

Anthracnose:  Brown spots up to ¼ inch in diameter go entirely through the leaf and have reddish brown halos.  Tiny dark brown fungal fruiting structures dot the brown areas. Small reddish brown spots without brown centers may pepper portions of the leaf or extend along the veins.

      Dogwood Anthracnos

Powder Mildew:  White fungal growth develops on the surface of leaves late in the summer and during autumn.

        Powdery Mildew

Dutch elm disease:  Leaves on one or more branches wilt, yellow, and fall prematurely.  Progressively more branches exhibit symptoms. Outer layers of sapwood of affected branches have brown streaks.

Leaf scorch:   Early to midsummer, leaves on a few branches have marginal leaf burn or scorch.  Symptoms increase on the leaves later in summer.  The boundary between live and dying tissue is wavy and has a definite halo. Leaves usually fall prematurely.  -More branches become involved in following years.

Insect and Mite Treatments

Insect control on your property for plant health consists of a management program that includes a thorough inspection of your landscape by a professionally trained/licensed expert  in the diagnosis and treatment of landscape insects, as well as careful monitoring. Insects and mites usually infest trees and shrubs that are in poor health and/or under stress. Therefore, your technician’s first priority is to restore the health of your trees and shrubs so that they can naturally resist insect and mite infestation. Our philosophy is to use low toxicity methods and ingredients to reduce populations of insects and mites with the least disruption to other beneficial insects and the environment
