on pesticide use for
industrial/commercial/government
sector and this much was spend for
home and garden sector in 2012
Define integrated pest management System that uses all available and suitable pest
control tactics to reduce pest populations to
tolerable levels while minimizing adverse
environmental side effects.
Explain how aesthetic thresholds Aesthetic thresholds are based on tolerance,
affect IPM tactics personal comfort, taste, plant appearance, and
specific site conditions.
Nurseries and the like have zero pest tolerance
whereas landscape plantings might have low
tolerance.
Healthy lawns have a higher threshold than
stressed, weakened lawns

Explain how IPM can reduce the use Pesticides are not meant to be a solution to all
of pesticides problems.
IPM provides the most effective solutions in all
regards, which may not always be pesticides.
List the six control strategies used in Cultural
IPM Mechanical
Host resistance
Biological
Regulatory
chemical
Define pesticide Any material used to kill, attract, repel, regulate, or
interrupt growth and mating of pests, or to
regulate plant growth
Contact pesticides Must physically touch the pest organism or be
sprayed on the site the pest frequents to exert an
action
Example would be protective fungicide
Must be re-applied to new plant tissues or if
precipitation washes product off
Systemic pesticide Enters the plant via roots or above ground plant
tissues and is moved inside of the plant.
Could render plant toxic to insect or mice
Could move through plant to kill parts of the plant
Example would be curative fungicide because it
penetrates the plant and stops disease
Preemergence Applied prior to weed seed germination.
Little to no effect on weeds that have emerged

Postemergence Applied to actively growing plants.
Work best in sunlight, high humidity, good soil
moisture
Selective pesticide Control only certain types or stages of pests while
leaving nontarget organisms unaffected.
Example would be herbicide that kills broadleaf
weeds and not turfgrass
Nonselective pesticide Exert their action on a wide variety of pests.
Control most of the plants they are sprayed on.
Identify the best application timing Plant diseases
for effective pest control as it For fungicides, it is critical that susceptible tissues
pertains to: plant diseases, insects, be protected before an infection begins or at the
and weeds first appearance of any symptoms
Insects
The younger the stage of insect, the more
susceptible it is to chemical control.
Weeds
Generally most effective when applied to actively
growing plants and least effective when plants are
not actively growing
Annual weeds are easiest to control in early spring
Biennials should be treated in fall or early spring
when in the rosette stage
Perennial weeds can be controlled in early bloom
stage or in the fall

Explain how pesticide resistance Resistance is the ability of a pest species that was
develops in a pest population once effectively controlled by a pesticide to
survive spray concentrations that were previously
effective.
It is an inherited trait that results from repeated
applications of pesticides with the same site of
action or mode of action.
Examples include pythium blight in turfgrass,
botrytis in ornamental, green peach aphid in
insects, and goosegrass weeds
State the importance of the numeric These codes help applicators quickly identify the
codes at the top of a pesticide label mode of action by looking at the group number.
and pesticide resistance Varying this can help reduce resistance
State four ways to minimize pesticide Correctly chosen nozzle
drift Reduced spray pressure
Monitor weather conditions
Keeping the spray nozzle near the target
Summarize the ways in which Contact can kill or injure plants
pesticides can injure nontarget Movement into the root zone where it can be
plants absorbed is also bad
List posting rules for a pesticide Required for urban areas or municipalities
application Notification signs must be posted at the start of an
application to a treatment site
4 by 5 inches, weather proof, and above grass line
"This are is chemically treated. Keep off. Do not
remove sign for 24 hours."
Explain how to clean up hard Blow or sweep the material back into the turfgrass
surfaces after a granular application area or on the plant beds.
Keep away from storm drain entrances
