Pest & Disease Management

To Keep Trees & Shrubs Healthy & Looking Their Best

Keep Shrubs and Trees Pest- and Disease-Free

Integrated Pest Management (IPM) is part of a well-developed Plant Health Care (PHC) program. It involves regular monitoring, anticipation, proper pest identification, establishing tolerable damage thresholds, and targeted biological and alternative pesticide treatments, when necessary, to keep insect and disease problems under control.

Our PHC technicians are trained not only to identify pests and diseases, but also to locate and identify beneficial predators and pollinators within the landscape at their various growth stages.

Our goal isn’t to exterminate every pest, but rather to keep populations below a level of esthetic and economical damage that you can live with. With some prey in the landscape, beneficial predators will be enticed to stay and dine.

Call us today at 908-309-6611 to schedule a complimentary assessment of your landscape.  Our pest and disease experts will provide you with a program and estimate customized to treat your specific trees and shrubs.

Pest & Disease Management Programs

Disease Management Program

Do you have trees or shrubs that are prone to fungal leaf diseases, such as anthracnose, rust, scab and canker? Plants that typically have problems include apple, boxwoods, crabapple, dogwood, hawthorn, laurel, pachysandra, rose, rhododendron, serviceberry and others.

Our Disease Management Program uses 3 treatments with a foliar and trunk application of bio-organic fungicide to suppress diseases. Treatments usually occur in mid/late-April, early May and late May/early June.

Spotted Lanternfly Suppression

We now offer spotted lanternfly treatments to suppress the egg-laying population and reduce the damage they cause. In the late summer (usually starting in late July - early August), we use a highly effective organic pesticide that is sprayed on trees and plants where spotted lanternflies gather. It quickly kills the adults feeding on the sap and minimizes the number of eggs that are laid (reducing the number of lanternflies that would otherwise hatch next year). The pesticide is made from botanically-derived active ingredients – pyrethrins, exacted from chrysanthemums - is OMRI listed, has no residual, and is suitable for use on organic crops.

Integrated Pest & Disease Management Programs

This program is ideal for properties with a moderate level of tree and shrub diversity, where there is evidence of insect and disease pressure. 

All vulnerable shrubs and trees under 20' in height are treated with our safe, organic products. These highly effective treatments are used to suppress common plant diseases, such as anthracnose, rust, scab and canker, as well as damaging insects like caterpillars, spider mites, scale, lacebug, aphids, whitefly and bagworm.

We're pleased to continue offering beneficial insects as part of our IPM program. These beneficials are used to bring down the population of harmful pests in your landscape. For example, green lacewings parasitize and kill aphids, while praying mantises are voracious predators of spotted lanternfly.

The timing and frequency of treatments depends on the diversity of plantings and the disease and pest issues on your property. Generally, the first treatment occurs in April with additional applications running through the end of summer.

Our technicians regularly inspect and monitor your property, anticipate and diagnose pest and disease problems, and as necessary apply the appropriate organic treatment(s) targeted for the specific pest. Following each visit, they'll leave a summary of findings and outcomes for your review.

FAQs: Pest & Disease Management

We're often asked about Plant Health Care, common tree and shrub problems, insect and disease treatment options and timing, and how homeowners can best take care of their trees and shrubs to keep them healthy and beautiful. While we have many detailed Plant Health Care resources on this website, we thought it would be helpful to quickly answer some of the most common questions here.

PHC stands for Plant Health Care, which is a fancy way of saying that we do all of the things necessary to keep plants (including trees, shrubs, lawns, and landscape plants) healthy. That includes fertilization and soil improvement, as well as identification, control, and prevention of problems caused by pests and diseases.

Integrated pest management (IPM) is a streamlined, ecological approach to pest management that gives you more effective results with less need for harmful chemicals. It is more effective in controlling the “bad bugs” in your yard and is safer for people, pets, and the environment compared to the traditional method of spraying everything with insecticide. Plus, IPM saves you money that would’ve otherwise been spent on unnecessary pesticides.

IPM includes regular monitoring of pest populations, the use of biological and cultural controls (including beneficial predators and pollinators), applying physical controls, planting pest-resistant varieties, and using organic pesticides.

The goal of IPM is to manage pest populations for long-term prevention, not necessarily to eradicate them entirely. If pest populations are kept down, they’ll cause fewer problems and little noticeable damage in your yard or garden.

Plant Health Care programs offered by Organic Plant Care provide preventive care or treatments for a wide range of plant pests and diseases. Examples of common pests and diseases we can help you with include:

Plant health care not only prevents issues, but it also maintains healthy plants. Well-cared-for plants, trees, and shrubs are better able to stave off destructive pests and diseases and recover from stressful situations.

For the best results, many of our PHC services are offered as an annual program, renewed by an updated proposal each year.

That depends on what you are treating.

Some tree diseases, for instance, are only stopped by preventive treatments; treatments must be applied before the disease has affected your tree. For example, trees and shrubs that are prone to certain fungal leaf diseases are preventively treated three times a year with a bio-organic fungicide, usually in late spring and early summer. Once the disease is visible, it’s too late to treat it.

Other treatments are applied only when the problem, whether it’s a pest or disease, is present. For example, we treat for Spotted Lanternfly when the adults are active and feeding on the leaves and sapwood.

In some cases, treatment may still be possible. In others, your tree or shrub may have already begun to decline and could be beyond saving.

Contact us for an inspection to determine the health and prognosis of your trees and shrubs.

There are many environmental conditions that can stress your trees. Common tree problems in central New Jersey include:

A stressed tree will be more susceptible to pests and disease. Contact us for a professional consultation so we can help you determine how to improve the overall health of your trees.

There are always new insects and diseases that are arriving in the Central New Jersey and Eastern Pennsylvania area, plus others that continue to spread rapidly. Given that prevention is often the best option, we recommend an annual inspection by a knowledgeable tree care professional. They will identify potential problems in your landscape (such as poor soil conditions), evaluate the health of your trees and shrubs, and recommend appropriate treatment options to increase plant vigor and head off problems before they start.

You should also call a professional if your trees or shrubs

  • show signs of decline (such as slow growth, small or yellowing leaves, prematurely dropping leaves, or dead branches)
  • have an insect infestation (check our extensive collection of information about garden pests for signs and symptoms) 
  • are affected by a disease (you'll usually notice signs of decline, strange growths on the tree, spots or fuzzy areas on leaves, mushrooms around the tree base, or other things that don't look "right", such as these tree diseases that are common in New Jersey and Pennsylvania

That depends. Many of the most effective insect and disease treatments can only be applied by professionally licensed pesticide applicators. While there are homeowner treatment options for small trees, these require careful application to avoid unintended environmental impacts. For example, products can leach into groundwater and some products are highly toxic to pollinators and aquatic invertebrates.

In general, we recommend having trees that are larger than 12-14 inches in diameter (as measured 4.5 feet from the ground) treated by a professional with the knowledge and equipment (such as a high-powered spray rig or tree injection kit) to do the job correctly.

Healthy plants start with healthy soil. For trees and shrubs, we can improve their vigor, health, and appearance with our annual fertilization and soil conditioner program, supplemented by Deep Root Fertilization every few years (and especially during times of drought or high stress for your trees and shrubs).

Plants that receive enough water and nutrients are naturally more resistant to pests and diseases. To help keep them healthy,

  • Check your irrigation system to make sure it’s working as scheduled and adjust it as needed.
  • Maintain mulch around the dripline of your trees and throughout shrub and mixed planting beds.
  • Enrich your soil with compost or compost soil conditioner for improved soil texture and water-holding capacity.
  • Protect your trees from damage by mowers, string trimmers, and other equipment.

A healthy garden should always have a mix of plants (including native plants) that attract wildlife, beneficial insects, pollinators, and beneficial predators. In many cases, the insects that transmit diseases can be eaten, killed, or parasitized by beneficial predators, including tiny parasitic wasps, praying mantises, dragonflies, spiders, and songbirds.
