3OT ASSESMENT TEST EXAMS
WITH CORRECT QUESTIONS AND
ANSWERS.
Define integrated pest management (ipm) - CORRECT ANSWERS✔️✔a️ system that uses all available
and suitable pest control tactics to reduce pest populations to tolerable levels while minimizing adverse
environment side effects.
Seeks to replace chemical eradication practices.
Most effective to pests
Explain how aesthetic thresholds affect IPM tactics - CORRECT ANSWERS✔️✔️(DEF) Damage level that
is unacceptable to the viewer
Based on tolerance, personal comfort, taste, plant appearance, and specific site & environmental
conditions
(EX) Landscape plantings can tolerate low-level pest populations, but nurseries that must sell only pest-
free plants can allow only very low injured levels
Healthy=higher threshold
Explain how IPM can reduce the use of pesticide - CORRECT ANSWERS✔️✔️In IPM, pesticides are used
only when needed and in combination with other approaches for more effective, long-term control.
Pesticides are selected and applied in a way that minimizes their possible harm to people, non-target
organisms, and the environment
List the 6 control strategies - CORRECT ANSWERS✔️✔️Cultural: modifying the environment
, Mechanical: physical means like fences, weeding
Host Resistance: the use of resistant crops verities
Biological: Natural enemies, ladybugs
Regulatory: monitoring, trapping, eradication
Chemical Process: kill the pests or inhibit their development
Define Pesticide - CORRECT ANSWERS✔️✔a️ ny material used to kill, attract, repel, regulate, or
interrupt growth and mating of pests, or to regulate plant growth
Compare contact and systemic pesticides - CORRECT ANSWERS✔️✔️Contact: must physically touch the
pest organism or be sprayed on the site the pest frequents to exert action. Must be re-applied to new
plant tissues or if precipitation washes the product off
Systemic: Enters the plant via the roots or above ground plant tissues and is moved inside the plant.
Renders the plant toxic to an insect feeding on it. Sometimes called a curative. Remain in the plant tell
dead (herbicides) or for several days, weeks, or months (insecticide, fungicide)
Compare preemergence and postemergence herbicides - CORRECT ANSWERS✔️✔️PRE: Applied prior
to weed seed germination
POST: Applied to weeds that are actively growing
Distinguish between selective and nonselective pesticides - CORRECT ANSWERS✔️✔S️ elective: will
control only certain types or stages of pests while leaving nontarget organisms unaffected
(EX) bacterial insecticides that only kill the immature stages of moths or selective herbicides that control
only broadleaf weeds and can be sprayed on a turf grass area
Identify the best application timing for effective pest control - CORRECT ANSWERS✔️✔️Plant diseases:
before any infection begins or at first appearance (oak wilt, scab on apples)
Insects: the younger the insect stage the more susceptible it is to chemical control. Should target the
stages for damages
