EPA reported this much was spent 1.4 billion; 3.3 billion
on pesticide use for
industrial/commercial/government
sector and this much was spend for
home and garden sector in 2012
Define integrated pest System that uses all available and suitable pest
management 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 Pesticides are not meant to be a solution to all
use of pesticides problems.
IPM provides the most effective solutions in all
regards, which may not always be pesticides.
List the six control strategies used Cultural
in 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
