Q1. What is the primary purpose of seed treatment in agriculture?
A. To improve the color and appearance of seeds
B. To increase the weight of seeds for better market value
C. To protect seeds and seedlings from pests, diseases, and environmental
stresses
D. To speed up the harvesting process
E. To reduce the need for irrigation
Correct Answer: C. To protect seeds and seedlings from pests, diseases, and
environmental stresses
EXPERT RATIONALE: Seed treatment is fundamentally applied to safeguard
seeds and young seedlings from soil-borne pathogens, insects, and other biotic and
abiotic stresses, ensuring better germination and crop establishment.
,Q2. Which of the following is classified as a Category 4 seed treatment
product?
A. Products with no active ingredients
B. Products used only for coloring seeds
C. Restricted-use pesticide products requiring certified applicator handling
D. Organic fertilizers applied at planting
E. Herbicides applied post-emergence
Correct Answer: C. Restricted-use pesticide products requiring certified
applicator handling
EXPERT RATIONALE: Category 4 seed treatment involves the application of
restricted-use pesticides to seeds. These require a certified applicator due to their
potential hazard to human health and the environment.
Q3. What does the term "seed priming" refer to?
A. Coating seeds with a thick layer of fertilizer
B. A pre-sowing technique that hydrates seeds to initiate germination
processes before drying and planting
C. Removing the seed coat to expose the embryo
D. Treating seeds with high temperatures to kill pathogens
E. Blending multiple seed varieties together
Correct Answer: B. A pre-sowing technique that hydrates seeds to initiate
germination processes before drying and planting
EXPERT RATIONALE: Seed priming involves controlled hydration of seeds
allowing pre-germinative metabolic processes to occur. Seeds are then re-dried
before planting, resulting in faster and more uniform germination.
,Q4. Which type of seed treatment involves applying a thin film of polymer
coating to seeds?
A. Seed pelleting
B. Film coating
C. Seed dressing
D. Seed dusting
E. Seed soaking
Correct Answer: B. Film coating
EXPERT RATIONALE: Film coating applies a thin, uniform polymer layer to the
seed surface. Unlike pelleting, it does not significantly change seed shape or size. It
is used to carry active ingredients such as fungicides, insecticides, and
micronutrients.
Q5. What is the role of a sticker or binder in seed treatment formulations?
A. To repel insects from seeds
B. To ensure active ingredients adhere firmly to the seed surface
C. To dissolve nutrients for easy uptake
D. To change the color of the seed coat
E. To speed up seed germination
Correct Answer: B. To ensure active ingredients adhere firmly to the seed
surface
EXPERT RATIONALE: Stickers or binders are additives in seed treatment
formulations that help active ingredients and other components stick firmly to the
seed surface, reducing dust-off and improving product efficacy.
, Q6. Which regulatory body oversees the registration of seed treatment
pesticides in the United States?
A. USDA Food Safety Inspection Service
B. FDA Center for Food Safety
C. Environmental Protection Agency (EPA)
D. Federal Trade Commission
E. Occupational Safety and Health Administration
Correct Answer: C. Environmental Protection Agency (EPA)
EXPERT RATIONALE: The EPA is responsible for registering and regulating all
pesticides used in the United States, including those used for seed treatment,
under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
Q7. What does PPE stand for in the context of seed treatment?
A. Plant Protection Equipment
B. Pesticide Protective Enclosure
C. Personal Protective Equipment
D. Product Performance Evaluation
E. Primary Pest Elimination
Correct Answer: C. Personal Protective Equipment
EXPERT RATIONALE: PPE refers to Personal Protective Equipment — gear worn
by applicators to protect against exposure to pesticides. This includes gloves,
respirators, protective clothing, goggles, and boots as specified on pesticide labels.
Q8. Which of the following pathogens is commonly targeted by fungicide seed
treatments?
A. Aphids
