IPM Trend & Follow-Up — Formative Check
Answer each item before opening its rationale. Use missed items to identify which lesson evidence you should revisit.
1. What makes two scouting rounds most comparable?
- Consistent route, sampling units/counts, observation definitions and traceable locations.
- The same total number of detections only.
- Different observers using different scales.
- Sampling only the worst plants each time.
Check answer and rationale
Answer: A. Consistent route, sampling units/counts, observation definitions and traceable locations.
Consistent route, sampling units/counts, observation definitions and traceable locations.
2. What does incidence describe?
- The intensity of damage on one plant.
- How many or what proportion of sampled units meet the defined finding.
- The legal status of a treatment.
- The amount of pesticide applied.
Check answer and rationale
Answer: B. How many or what proportion of sampled units meet the defined finding.
How many or what proportion of sampled units meet the defined finding.
3. Why repeat scouting after an authorized intervention?
- Because intervention completion itself proves success.
- To replace the baseline with newer data.
- To measure whether the intended outcome occurred and whether spread or pressure changed.
- Only to collect photographs.
Check answer and rationale
Answer: C. To measure whether the intended outcome occurred and whether spread or pressure changed.
To measure whether the intended outcome occurred and whether spread or pressure changed.
4. What is the purpose of a quarantine boundary?
- To increase airflow.
- To eliminate the need for scouting.
- To authorize treatment.
- To limit movement from suspect/affected material or areas into clean production while risk is evaluated or controlled.
Check answer and rationale
Answer: D. To limit movement from suspect/affected material or areas into clean production while risk is evaluated or controlled.
To limit movement from suspect/affected material or areas into clean production while risk is evaluated or controlled.
5. What should happen to an inconvenient but valid scouting observation?
- Keep it in the record and interpret it with the rest of the evidence.
- Delete it if it conflicts with the leading hypothesis.
- Move it to another round.
- Replace it with the room average.
Check answer and rationale
Answer: A. Keep it in the record and interpret it with the rest of the evidence.
Keep it in the record and interpret it with the rest of the evidence.
6. Does this course authorize independent pesticide application?
- Yes, after passing the written final.
- No; treatment selection/mixing/application remains governed by separate legal, label, facility and role authorization.
- Yes, for low-risk products.
- Yes, if the diagnosis is certain.
Check answer and rationale
Answer: B. No; treatment selection/mixing/application remains governed by separate legal, label, facility and role authorization.
No; treatment selection/mixing/application remains governed by separate legal, label, facility and role authorization.
7. A clean-looking room was checked at only two doorway plants. What can be concluded?
- The room is confirmed pest-free.
- Negative findings need no sample count.
- The limited sampling should be documented; it does not establish facility-wide absence.
- Doorway plants represent all zones automatically.
Check answer and rationale
Answer: C. The limited sampling should be documented; it does not establish facility-wide absence.
The limited sampling should be documented; it does not establish facility-wide absence.
8. Why annotate scouting findings on a map?
- To replace incidence counts.
- To authorize treatments.
- To avoid recording crop identity.
- To reveal clustering, spread, contraction and relationships to batches or movement pathways.
Check answer and rationale
Answer: D. To reveal clustering, spread, contraction and relationships to batches or movement pathways.
To reveal clustering, spread, contraction and relationships to batches or movement pathways.
9. What is a confounder in treatment follow-up?
- A simultaneous change that can affect the outcome and complicate attribution to the intervention.
- A guaranteed treatment failure.
- A type of pesticide label.
- A fixed trap location.
Check answer and rationale
Answer: A. A simultaneous change that can affect the outcome and complicate attribution to the intervention.
A simultaneous change that can affect the outcome and complicate attribution to the intervention.
10. When a needed inspection would breach quarantine, what should the technician do?
- Break quarantine briefly.
- Use an approved contained method or escalate rather than breaking the boundary.
- Move material to a clean area.
- Skip all future inspection.
Check answer and rationale
Answer: B. Use an approved contained method or escalate rather than breaking the boundary.
Use an approved contained method or escalate rather than breaking the boundary.
11. What belongs in a next-round follow-up plan?
- Only the next date.
- Only the previous treatment name.
- Comparable sampling method, locations, timing, outcome metrics, containment and escalation triggers.
- Only the final diagnosis.
Check answer and rationale
Answer: C. Comparable sampling method, locations, timing, outcome metrics, containment and escalation triggers.
Comparable sampling method, locations, timing, outcome metrics, containment and escalation triggers.
12. What is the correct response when a new treatment decision is outside assigned authority?
- Choose a treatment from prior experience.
- Apply a smaller dose without approval.
- Delay documentation until after treatment.
- Escalate the evidence and requested decision to the authorized role while maintaining current controls.
Check answer and rationale
Answer: D. Escalate the evidence and requested decision to the authorized role while maintaining current controls.
Escalate the evidence and requested decision to the authorized role while maintaining current controls.
