Insect & Disease Management
Pest presence does not constitute a pest problem. A pest becomes a problem when its population or the injury it causes, exceeds a tolerable level known as an action threshold. Insects such as ticks and certain vertebrates can be considered pests since they reduce personal enjoyment or safety in the landscape. Some pest problems result from organisms eating or inhabiting desirable plants, which can cause both physiological and aesthetic plant injury. As this level increases, control measures should be quickly implemented.
Monitoring your landscape is an important component of Integrated Pest Management (IPM). Homeowners and landscape technicians can perform routine inspections to make observations and collect crucial information such as:
- Site information (weather, landscape conditions)
- Plant information (condition, developmental stage)
- Pest information (identification, population level, life stage)
Many landscape pests can only be effectively managed during a vulnerable life stage. Certain insects cannot be controlled with pesticides once they reach adulthood and develop their protective wax covering. Employing tactics inappropriate for the pest life stage is a waste of time and resource. A Rayal Tree Care arborist or skilled technician is familiar with key pests and key plants in a particular region or specific property. We are skilled in the life history of these pests, signs and symptoms of the injury they cause, and appropriate management tactics. Whiteflies, Aphids, Thrips and Scales are some of the many pests we control.

Some of the more common diseases we treat for are:
Harmful bacteria, fungi and viruses may cause diseases of trees and shrubs. Some diseases can kill trees in a short period of time while others can virtually eliminate an entire tree species. The Rayal Tree Care Company programs are designed to prevent and control various diseases that attack specific tree and landscaping on your property. Our arborist can correctly identify the species of tree / bush and the particular disease characteristic which is effecting its health.
- Cedar-apple rust
- Dutch Elm
- Elm leaf beetle
- Elm Leaf Black Spot
- Fire Blight
- Oak Wilt
- Tar spot
- Verticillium wilt
An arborist or experienced technician from the Rayal Tree Care Company will consider these observations when making a disease diagnosis in certain cases (ex. orchard):
- Disease symptoms may vary slightly from season to season and on their time of appearance, often depending on environmental conditions.
- Always obtain fresh disease samples. Secondary organisms will often follow the primary pathogen and make diagnosis difficult or impossible.
- Record the varieties and rootstocks that are affected. Susceptibility of apple varieties and rootstocks to some diseases will vary greatly and may give a valuable clue to diagnosis.
- The distribution of symptoms within an orchard and in individual trees will often aid in determining if the disorder is caused by a pathogen and how it spreads in the orchard.
- Observe the areas surrounding the orchard for alternate hosts, abandoned orchards, and other sites of potential disease reservoirs. Observe the orchard configuration, contour, and soil type(s).
- Complete records containing timings and rates of all pesticides, growth regulators, and fertilizers may be helpful in determining the problem.
- Records of previous years weather patterns, such as excessive rains, drought or extremely cold winter periods, along with grower cultural practices in the orchard may help in diagnosis.
- A history of previous orchard problems should be obtained if possible.
Correct diagnosis requires a careful examination of the situation by a trained eye. Many plant health problems exhibit similar symptoms. A site visit from a certified arborist from The Rayal Tree Care Company can determine the nature of the problem. Proper treatment is based on an accurate identification of the host plant and the causal agent. Trees and shrubs are the focus of the program because they represent a long-term investment in your landscape.
