Integrated Pest Management

Integrated pest management (IPM)
Agricultural practice that uses a variety of techniques designed to minimize pesticide inputs.
Element
Any substance that cannot be broken down into simpler substances.
Compound
A substance formed by chemical union of two or more elements or ingredients in definite proportion by weight.
Inorganic compound
Any compound that does not contain carbon.
Disease
An impairment of health or a condition of abnormal functioning.
Vector
A variable quantity that can be resolved into components.
Insect
A class of small arthropod animals that has three separate sections to their bodies.
Arachnid
Air-breathing arthropods characterized by simple eyes and four pairs of legs.
Defoliate
Strip the leaves or branches from.
Weed
Any plant that crowds out cultivated plants.
Pathogen
Any disease-producing agent.
Annual weed
Completes life cycle in one growing season.
Biennial weed
A weed that will live for 2 years.
Perennial weed
A weed that lives for more than 2 years.
Rhizome
A horizontal plant stem with shoots above and roots below serving as a reproductive structure.
Node
A point along the stem of a plant at which leaves are attached.
Stolon
A horizontal branch from the base of plant that produces new plants from buds at its tips.
Meristematic tissue
Plant tissue found only in the tips of shoots and roots; responsible for plant growth.
Noxious weed
A weed that is the hardest kind to control and causes damage to those plants around it.
Exoskeleton
Hard protective structure developed outside the body.
Entomophagous
Feeding on insects.
Plant disease
A disease that affects plants.
Causal agent
Any entity that causes events to happen.
Disease triangle
Susceptible host plant, virulent pathogen, conducive environment.
Drift
Wander from a direct course or at random.
Vapor drift
The movement of chemical vapors from the application site.
Cultural control
Use of optimal crop growth conditions to out compete weeds.
Clean culture
Any practice that removes breeding or overwintering sites of a pest.
Trap crop
Attracts insects away from economically important crops.
Biological control
A method of pest control that involves the use of naturally occurring disease organisms, parasites, or predators to control pests.
Cultivar
a variety of a plant developed from a natural species and maintained under cultivation.
Chemical control
The use of pesticides to reduce pest populations.
Pesticide resistance
Insects develop resistance to pesticides over time which they then transfer to their offspring who entirely resistant.
Pest resurgence
Rebound of pest populations due to acquired resistance to chemicals and nonspecific destruction of natural predators and competitors by broadscale pesticides.
Pheromone
A chemical substance secreted externally by some animals that influences the physiology or behavior of other animals of the same species.
Organic compound
Any compound of carbon and another element or a radical.
Quarantine
Isolation to prevent the spread of infectious disease.
Targeted pest
Identified pest that, if introduced, poses a major economic threat.
Eradication
A chemical substance secreted externally by some animals that influences the physiology or behavior of other animals of the same species.
Key pest
A pest that occurs on a regular basis for a given crop.
Pest population equilibrium
A condition that occurs when the number of pests stabilizes or remains steady.
Economic threshold level
The level of pest damage to justify the cost of a control measure.
Monitoring
The act of observing something.
