Anything that affects the growth, quality, and appearance of a plant
The use of different pest management strategies to maintain a landscape
A pesticide-only approach is one-layered Environmentally unsound Economically unfeasible
Use several management practices together
Establish thresholdsScouting and identificationPreventionControl
Provides long-term solutions to pest problems
Protects the environmentReduces pesticide costs and
liabilitiesLimits development of pesticide
resistanceGood for public relations
More labor costs for training and scouting
More to learn, more to remember
To reduce pesticide resistance
To reduce water contamination
Avoid harm to non-target organisms
Avoid pesticide movement in the environment
It’s genetic Insects that carry the resistance gene
do not die when exposed to pesticide The resulting offspring also carry the
gene Factors influencing resistance
Broad spectrum pesticides = > resistance Increased pesticide use = > resistance Pesticides that provide good control = >
resistance
Never rely on a single pesticide class.
Integrate chemical control with effective, complementary cultural and biological control practices.
Always use pesticides at recommended rates and strive for thorough coverage.
A non-target organism is anything that the pesticide is not intended for Can be harmed
directly (contact) Harmed by
residue or accumulation

Drift – when pesticide move through the air
Leaching – when pesticide moves downward through soil
Runoff – when pesticide moves with water off of a surface (e.g., roads, sidewalks, roofs)
Surface runoff and leaching may occur when: Too much liquid
pesticide is applied, leaked or spilled
Too much rainwater, irrigation water or other water gets onto a surface containing pesticide residue

Drift, leaching and runoff
Spills, leaks and back-siphoning
Improper disposal of pesticides, rinsates and containers

Soil texture – sand, silt, and clay
Soil permeability –how fast water can move downward
Soil organic matter – influences how much water the soil can hold before it moves downward
What can you do to prevent pests? Right plant, right place Proper pruning, fertilization, watering,
mulching, spacing, etc. Installation and establishment Choosing pest resistant cultivars/species Proper site preparation
Avoid monocultures (what’s that?)Start with pest-free, weed-free plantsReduce food, water, and shelter that
might attract pests Attract natural predators!!
Observe planting datesSanitation
Scout the landscape frequently for pest problems Reduces the spread of
the pest Reduces the amount of
pesticides used Reduces cost May allow for the use
of less harmful control measures
Learn key plants and key pests When do they emerge? When is their
peak season?Keep records of pest numbers, type
of damage, number of beneficials, growth and health of the plant, soil conditions, weather, etc.
What kinds of pests are present?Are the numbers great enough to
warrant control?When is the right time to begin
control?Have the control efforts successfully
reduced the number of pests?
