An Integrated Approach
Bartlett Tree Experts uses an integrated approach to managing insects and diseases that begins with maintaining plant health using sound cultural practices including pruning and creating optimal soil conditions for plant growth. Periodic inspections are essential to detect pest infestations before they reach damaging levels. Bartlett arborists are trained to recognize beneficial insects that will help naturally suppress pest populations, and we also release beneficials to augment existing populations. When treatments are necessary, Bartlett can apply organic and naturally based materials and reduced-risk products that provide effective pest suppression while protecting people and the environment.
Top-10 Insects
Hundreds of insect species damage leaves, stems, and branches; roots; and flowers and fruit of landscape plants. But not all insects on trees and shrubs are damaging. Some are beneficial and may help pollinate flowers or could be predators or parasites on insects that damage plants. Bartlett arborists are trained to correctly identify these beneficial insects and mites and can devise effective management programmes that protect landscape plants from serious damage while conserving beneficial organisms.

Top-10 Diseases
Diseases are abnormalities in trees and shrubs caused by microorganisms such as fungi and bacteria and by environmental stress such as drought, temperature extremes, and air pollution. Diseases are often difficult to diagnosis as different causal agents can produce similar symptoms. Accurate diagnosis is essential to developing effective treatment programmes. Bartlett operates a modern diagnostic laboratory to support pest management services to ensure accurate identification and treatment of plant problems.

Horse Chestnut Leaf Miner
A widespread, damaging pest of horse chestnut, the larvae tunnel into leaves resulting in brown patches on the leaf surface.
Oak Processionary Moth

Ash Dieback
Chalara ash dieback is caused by a fungus that results in premature leaf loss and crown dieback in ash trees.

- Is Arborbiotic injected into the root collar or trunk flair? I understand that Arborbiotic injections may not completely control fire blight on a Callery 'Redspire' pear (Pyrus calleryana) even with a fertilisation programme using Forti Phite plus calcium and the tree will need to be injected every year. I also understand the branches that are infected with fire blight will need to be pruned six inches back from the infection and pruning tools sterilized after each pruning cut.
