Integrated Pest Management and Organic Management Lecture

A set of vocabulary flashcards covering the definitions, strategies, and ecological concepts of Integrated Pest Management (IPM) as discussed in the Module 12 lecture.

Integrated Pest Management (IPM)

An ecosystem-based strategy and sustainable approach to managing pests using a combination of biological, cultural, physical, and chemical control strategies to minimize economic, environmental, and health impacts.

Pest Eradication

The complete elimination of a pest population; unlikely in most management situations, as IPM focuses on reducing populations below damaging levels.

Key Pest

A pest that causes major damage on a regular basis, such as the Codling moth in walnut growing regions.

Secondary Pest

A pest that becomes problematic after the treatment of a key pest disrupts the balance of natural predators or competitors, such as aphids appearing after Codling moth treatments.

Occasional Pest

Organisms that exhibit seasonal populations or "boom and bust" cycles and are not a regular presence in the landscape.

Monitoring (Scouting)

The process of observing a landscape or greenhouse, often using traps or physical inspection, to identify pest populations and determine if control strategies are necessary.

Sanitation

The removal of diseased, dying, or decaying plant material (inoculum) to prevent the spread of fungal or bacterial pathogens.

r-strategist

Organisms characterized by rapid growth and reproduction, often resulting in boom-and-bust population cycles, such as annual weeds.

k-strategist

Organisms that are slower growing but highly competitive and persistent within the landscape, such as perennial weeds.

Disease Triangle

The conceptual model showing that for a disease to occur, there must be a susceptible host, a conducive environment, and the pest or pathogen itself.

Leaf Wetness

The presence of free water or high humidity on a plant's surface; it is a primary driver for fungal and bacterial infections such as Anthracnose or Phytophthora.

Dollar Spot

A lawn disease that creates circular spots about the size of a silver dollar; its risk can be modeled using relative humidity, leaf wetness, and air temperature.

Monoculture

A landscape or agricultural system consisting of the same species or cultivar, which can be more easily attacked and destroyed by specific pests.

Respondus LockDown Browser

The specific digital tool required for students to take the final exam for this course.

Anthracnose

A disease commonly found on tomatoes that can cause infection when the plant tissue remains wet for $10$ to $50$ hours.

Phytophthora

A pathogen causing leather fruit rot on strawberries that can infect the plant with as little as a half hour of leaf wetness.
