manage processes to reduce pest populations to tolerable stages whilst minimizing negative
environmental aspect results.
Explain how aesthetic thresholds have an effect on IPM methods - ANSAesthetic thresholds are
primarily based on tolerance, non-public consolation, flavor, plant appearance, and particular
website online conditions.
Nurseries etc have 0 pest tolerance whereas panorama plantings might have low tolerance.
Healthy lawns have a better threshold than pressured, weakened lawns

to all issues.

of pests, or to modify plant increase
Contact pesticides - ANSMust physically contact the pest organism or be sprayed at the website
online the pest frequents to exert an motion
Example would be defensive fungicide
Must be re-carried out to new plant tissues or if precipitation washes product off
Systemic pesticide - ANSEnters the plant thru roots or above floor plant tissues and is moved
interior of the plant.
Could render plant poisonous to insect or mice
Could move via plant to kill elements of the plant
Example could be curative fungicide as it penetrates the plant and prevents disease
Preemergence - ANSApplied previous to weed seed germination.
,Little to no effect on weeds that have emerged
Postemergence - ANSApplied to actively developing vegetation.
Work quality in daylight, high humidity, top soil moisture
Selective pesticide - ANSControl only sure kinds or levels of pests while leaving nontarget
organisms unaffected.
Example might be herbicide that kills broadleaf weeds and not turfgrass

Control most of the plant life they're sprayed on.
Identify the first-class software timing for effective pest control as it pertains to: plant illnesses,
bugs, and weeds - ANSPlant sicknesses

The more youthful the level of insect, the greater inclined it's far to chemical manage.
Weeds
Generally most effective while implemented to actively growing plants and least effective whilst
vegetation are not actively developing
Annual weeds are easiest to govern in early spring
Biennials need to be treated in fall or early spring when in the rosette stage
Perennial weeds may be managed in early bloom stage or in the fall
Explain how pesticide resistance develops in a pest population - ANSResistance is the ability of
a pest species that changed into as soon as efficiently managed by a pesticide to live to tell the
tale spray concentrations that were previously effective.
It is an inherited trait that effects from repeated programs of insecticides with the same website
online of action or mode of action.
Examples encompass pythium blight in turfgrass, botrytis in decorative, green peach aphid in
insects, and goosegrass weeds
State the importance of the numeric codes on the pinnacle of a pesticide label and pesticide
resistance - ANSThese codes assist applicators quick discover the mode of action with the aid
of looking on the institution wide variety.
Varying this may help lessen resistance
State four approaches to reduce pesticide go with the flow - ANSCorrectly chosen nozzle
Reduced spray pressure
Monitor climate situations
Keeping the spray nozzle near the target
, Summarize the methods in which insecticides can injure nontarget flora - ANSContact can kill or
injure vegetation
Movement into the root region wherein it is able to be absorbed is also bad
List posting regulations for a pesticide software - ANSRequired for city regions or municipalities
Notification signs and symptoms should be posted on the start of an application to a remedy
website online
4 with the aid of 5 inches, climate proof, and above grass line
"This are is chemically treated. Keep off. Do no longer dispose of signal for twenty-four hours."
Explain the way to clean up tough surfaces after a granular software - ANSBlow or sweep the
cloth again into the turfgrass place or at the plant beds.
Keep far from typhoon drain entrances
List characteristics of water which can affect the effectiveness of a spray mixture - ANSWater
pH is one location of subject.
If the water is alkaline (pH greater than 7) it could motive alkaline hydrolysis.
If water is acidic (pH less than 7) it is able to cause acid hydrolysis
Hardness of water is any other challenge
Hardness is the quantity of dissolved minerals in water
Can inactivate insecticides
Most groundwater in Iowa has a pH between - ANS6.5 and 8.Zero
Wiper software
Pesticide carried out to selected flora thru a rope-wick device
pesticide software methods for soil - ANSSurface soil application
Applied at once to the naked ground inside the goal location
Soil drench
Pouring a diluted pesticide combination on the soil floor across the base of the plant
Soil injection
Placed a pesticide below strain 4-6 inches below the soil surface, usually encircling decorative
pesticide software methods for trunk - ANSBark spray
Pesticide applied to the woody portions of the decorative plant
