IPM is a systematic approach to pest management that aims to minimize pest populations while maintaining a healthy ecosystem. It emphasizes prevention, monitoring, and the use of a variety of control methods, including cultural, mechanical, biological, and chemical options.
Arborists use Integrated Pest Management (IPM) to protect trees from pests and diseases in a sustainable and environmentally friendly way. IPM involves a comprehensive approach that combines various strategies to control pests and minimize harm to the environment, human health, and the tree itself.
Arborists using IPM first identify the pest or disease affecting the tree. They then choose control methods based on the specific pest or disease, the tree species, and the surrounding environment. These methods may include cultural practices such as proper watering and fertilization, mechanical controls such as pruning or trapping, biological controls such as introducing beneficial insects, and chemical controls used only when necessary and in a targeted manner.
The benefits of IPM include reduced reliance on synthetic pesticides, protection of beneficial wildlife, and lower pesticide residue risks. Challenges of IPM include the necessity for specialized knowledge, potential higher initial costs compared to chemical controls, and the risk of pest resistance development. Arborists address these challenges by collaborating within IPM frameworks, thereby improving the overall effectiveness of pest management strategies.
What is Integrated Pest Management (IPM)?
Integrated Pest Management (IPM) is a sustainable approach to managing pests in trees, focusing on preventing damage and maintaining tree health. It involves monitoring tree health, implementing preventive measures, and using a combination of control methods, including biological, mechanical, and chemical controls. IPM aims to minimize chemical use while maximizing tree health and environmental protection.
According to Brunner, J.F. (2014) study Integrated Pest Management in Tree Fruit Crops, IPM emerged in the late 1950s due to agricultural concerns about the overuse of synthetic pesticides and their ecological consequences. IPM is grounded in ecological principles, particularly population biology, and aims to manage pests in various settings, including agricultural, forest, and urban environments.
IPM is a multi-faceted approach that integrates diverse pest control methods such as varietal resistances, cultivation, mechanical, biological, and chemical control, based on specific field conditions.
IPM offers a science-based approach that emphasizes prevention, monitoring, and targeted control methods to address pest issues in trees. It covers a wide range of pests, including insects, diseases, and weeds, tailored to individual tree needs and environmental considerations.
In the evolution of tree care practices, IPM has emerged as a response to concerns about the environmental impact of chemical pesticides. By prioritizing prevention, monitoring, and diverse control methods, IPM has become a holistic and effective strategy for managing pests in trees.
How Does IPM Work in Practice?
The IPM process works by regular monitoring and accurate identification of tree health issues. Practitioners then establish action thresholds, determining the pest population levels or damage tolerances that warrant intervention.
From there, IPM emphasizes preventive strategies, such as promoting tree vigor through proper cultural practices and encouraging natural predators. If pests exceed action thresholds, IPM utilizes biological, physical, and chemical control methods, with pesticides used only as a last resort and in a targeted manner.
Throughout the process, IPM practitioners continuously evaluate the effectiveness of their strategies, adjusting the plan as needed based on monitoring data and changing conditions. By employing this multi-faceted, adaptive approach, IPM aims to manage tree pests and diseases in an environmentally responsible and cost-effective way.
Usage of Integrated Pest Management in Tree Care
The usages of integrated pest management in tree care include monitoring tree health, setting up preventative measures, implementing integrated control methods, developing a tree care plan, evaluating IPM effectiveness, and more.

The core of an IPM approach involves employing a diverse range of biological, chemical, and physical/mechanical control techniques in a coordinated manner. By integrating multiple complementary control strategies, IPM practitioners can effectively manage pests and diseases while minimizing the reliance on any single control method.
Biological Control
Biological control is one of the most effective and environmentally friendly approaches to integrated pest management (IPM). It involves utilizing naturally occurring organisms, such as predators, parasites, and pathogens, to suppress pest populations and minimize the need for synthetic pesticides. This strategy promotes a more balanced and sustainable ecosystem within the tree care environment.
According to Orr, David’s 2009 chapter “Biological Control and Integrated Pest Management” from the book “Integrated Pest Management: Innovation-Development Process,” biological control involves practices like mass production, release of natural enemies, and invasion, where natural enemy populations are increased to eliminate pests.
Biological control methods in IPM utilize natural interactions between organisms to manage pests by introducing beneficial insects, mites, or fungi that prey on or parasitize the target pests. Common biological agents include predatory insects like ladybugs and lacewings, parasitic wasps, and beneficial fungi. These agents establish a healthy balance in the ecosystem, reducing the need for artificial interventions and minimizing harm to beneficial organisms.
Chemical Control
Chemical control is a component of IPM, utilized as a last resort and strategically to minimize environmental impact. Pesticides are selected carefully within IPM, focusing on the least toxic options, targeted application, and minimal effective dosage. The goal is to reduce reliance on pesticides by emphasizing preventive measures, biological control, and cultural practices, using chemical control sparingly.
IPM practices reduce insecticide applications by 95% while maintaining or enhancing crop yields. According to Pecenka, Jacob R. et al.’s 2021 study ‘IPM reduces insecticide applications by 95% while maintaining or enhancing crop yields through wild pollinator conservation’, IPM is a central organizing principle for pesticide use, optimizing inputs and preventing overuse.
Physical and Mechanical Control
Physical and Mechanical Control methods are non-chemical approaches used in IPM to directly manipulate pests or their environment to reduce populations. These techniques are often used by arborists with other IPM tactics, offering a more sustainable and environmentally friendly way to manage pests.
Physical and mechanical control techniques include:
- Barriers: Creating physical obstacles to prevent pest entry or movement. This can involve using netting, screens, fences, or other physical barriers to keep pests out of specific areas.
- Traps: Capturing and eliminating pests using various trapping methods. This can include sticky traps, pheromone traps, or other devices designed to lure and trap specific pests.
- Mechanical removal: Physically removing pests from the environment. This may involve handpicking insects, vacuuming pests, or using other manual methods to remove pests from trees or surrounding areas.
- Cultivation: Utilizing mechanical techniques to manipulate soil conditions and control pests. This could involve tilling the soil, removing weeds, or creating barriers to disrupt pest habitats.
Physical and mechanical control methods are highly effective in targeted scenarios, such as using netting to shield fruit trees from birds, installing screens to deter insect entry, and employing pheromone traps for insect population monitoring and control.
