Integrated Pest Management Program

Department of Plant Science and Landscape Architecture, Department of Extension

Management Practices

IPM Concepts

The practice of integrated pest management involves the application of several principles which are described below.

IPM Tactics

IPM programs integrate a diversity of tactics or tools to provide effective pest suppression while minimizing economic, ecological and human health risks. IPM tactics are described below.

Cultural Controls

Cultural controls involve the manipulation of the pest's biological and physical environment to make it less suitable. Examples include crop rotations, sanitation, and irrigation and water management.

Biological Control

Biological control is the use of living organisms such as parasitoids (parasites), predators or pathogens to suppress a pest population. Ladybeetles are common examples of predators employed in biological control. Bacteria such as Bacillus thuringiensis (Bt) is a well-known insect pathogen employed in many IPM programs.

Use of Resistant Cultivars

This tactic involves the use of plant cultivars which have inherited characteristics that defend the plants against pest attack. The use of resistant cultivars is an important step in plant pathogen, nematode and insect pest management.

Behavioral Modification

Behavioral modification tactics involve the use of visual, chemical or auditory stimuli to influence or disrupt normal pest behavior. Examples range from the old-fashion scarecrow to the modern uses of sex pheromone mating disruption for insect pest management.

Physical and Mechanical Controls

Physical controls involve the use of physical barriers against the pest or the manipulation of heat or air gas composition to kill the pest. Mechanical control includes the use of manual labor or of machinery to remove or kill the pest organisms.


The use of pesticides requires a careful selection and judicious use of pesticides which pose a low risk to human health, non-target species and the environment. The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) defines pesticides as any substance or mixture of substances intended for preventing, destroying, repelling or mitigating any insects, rodents, nematodes, fungi or weeds, or any other forms of life declared to be pests. It also includes as pesticides any substance or mixture of substances intended for use as a plant regulator, defoliant, or desiccant. See information below for more information on certain pesticide materials.

Regulatory Control

Regulatory control refers to state and federal regulations that prevent the spread of pest organisms.
