1. Which of the following best describes the primary purpose of pesticide
seed treatments in Canadian commercial agriculture?
A. To increase soil nutrient content before planting
B. To protect seeds and emerging seedlings from insects, fungi, and other
early-season pests
C. To eliminate all weeds before germination begins
D. To replace the need for post-emergence pesticide applications
Answer: B
Rationale: Seed treatments are specifically applied to seeds to protect
them during germination and early growth stages from pests such as fungi
and insects, improving establishment success and reducing early crop
losses.
2. In Canada, seed treatment pesticides must generally be registered
under which legislation before commercial use?
A. Food and Drugs Act only
B. Seeds Act only
,C. Pest Control Products Act
D. Fisheries Act
Answer: C
Rationale: The Pest Control Products Act governs the registration,
evaluation, and approval of pesticide products in Canada, including those
used for seed treatment applications.
3. Which pesticide class is most commonly used in seed treatment to
control seed-borne fungal diseases?
A. Herbicides
B. Fungicides
C. Rodenticides
D. Defoliants
Answer: B
Rationale: Fungicides are widely used in seed treatment programs because
they effectively prevent and control fungal pathogens that can infect seeds
and seedlings.
4. A key regulatory requirement for treated seed packaging in Canada is:
A. It must be sold only in retail stores
B. It must contain fertilizer mixed with seed
C. It must be labeled to indicate chemical treatment and associated hazards
D. It must be colorless to avoid consumer bias
Answer: C
Rationale: Treated seed must be clearly labeled with information about
the pesticide used and appropriate hazard warnings to prevent misuse and
ensure safe handling.
, 5. The main reason seed treatments are applied before planting rather
than after emergence is:
A. To improve irrigation efficiency
B. To ensure early protection during germination when seedlings are most
vulnerable
C. To reduce seed weight for easier transport
D. To increase photosynthesis rate immediately
Answer: B
Rationale: Seeds are most vulnerable during germination and early
growth, so applying treatments before planting ensures protection during
this critical developmental stage.
6. Which statement best describes systemic seed treatment pesticides?
A. They remain only on the outer surface of the seed
B. They evaporate immediately after planting
C. They are absorbed and move within the plant as it grows
D. They only work in dry soil conditions
Answer: C
Rationale: Systemic seed treatments are taken up by the germinating plant
and distributed internally, providing ongoing protection as the plant
develops.
7. In seed treatment operations, calibration of equipment is important
primarily to ensure:
A. Seeds germinate faster
B. Uniform and accurate pesticide application rates
C. Reduced need for seed storage
D. Elimination of all pesticide residues in soil
Answer: B
, Rationale: Proper calibration ensures that the correct amount of pesticide
is applied evenly to seed batches, preventing under- or over-application
and improving safety and efficacy.
8. Which hazard is most associated with improper handling of treated
seed?
A. Increased rainfall runoff
B. Human and livestock exposure to toxic pesticide residues
C. Soil compaction
D. Reduced seed viability due to temperature alone
Answer: B
Rationale: Treated seeds contain pesticide coatings that can pose health
risks if handled improperly, especially through ingestion, inhalation, or skin
exposure.
9. Which labeling requirement is commonly found on treated seed bags
in Canada?
A. “Certified organic product”
B. “Safe for immediate consumption”
C. “Do not use for food or feed”
D. “Guaranteed pest-free yield”
Answer: C
Rationale: Treated seed labels must clearly state that the seed is not
intended for food or feed use to prevent accidental consumption by
humans or animals.
10. What is the primary function of dye added to pesticide-treated
seed?
A. To increase germination rate
B. To improve nutrient absorption
