1. The primary purpose of applying pesticides to seed before planting is to:
A. Increase seed size and improve harvest weight
B. Protect seeds and seedlings from pests during early growth stages
C. Replace all future crop protection applications
D. Eliminate the need for proper soil preparation
Answer: B
Rationale: Seed treatments are designed primarily to protect seeds and young
seedlings from insects, fungi, and other pests during the vulnerable germination
and establishment period. They do not replace good agronomic practices, soil
management, or later pest management decisions. Proper seed treatment
improves stand establishment by reducing early losses caused by seed- and soil-
borne pests.
2. Which type of pesticide formulation is commonly used for treating seed
because it adheres well to the seed surface?
A. Emulsifiable concentrate
B. Wettable powder only
C. Flowable suspension or liquid seed treatment formulation
D. Granular formulation
,Answer: C
Rationale: Liquid flowable suspension formulations are commonly used in
commercial seed treatment because they can be evenly distributed over seed
surfaces and provide good adhesion after drying. Proper formulation helps
ensure accurate pesticide placement, reduces dust, and improves operator
safety compared with some older dry formulations.
3. A seed treatment applicator notices uneven pesticide coverage on treated
seed. The most likely cause is:
A. Incorrect mixing, application rate, or equipment calibration
B. Excessive seed germination percentage
C. Low soil fertility
D. Excessive sunlight exposure after planting
Answer: A
Rationale: Uneven coverage usually results from problems with equipment
calibration, inadequate mixing, improper treatment speed, or incorrect pesticide
volume. Uniform coating is critical because untreated areas may allow pests to
damage seedlings while over-treated areas may increase the risk of seed injury.
4. Before applying a seed treatment pesticide, the applicator should first:
A. Increase the pesticide concentration to ensure effectiveness
B. Read and follow the pesticide label directions
C. Mix multiple products without checking compatibility
D. Apply the product directly without calibration
Answer: B
Rationale: The pesticide label is the legal source of instructions for application
rates, approved crops, safety requirements, mixing directions, and restrictions.
,Following the label prevents misuse, protects workers and the environment, and
ensures compliance with pesticide regulations.
5. Seed treatment pesticides that control fungal diseases are generally classified
as:
A. Herbicides
B. Fungicides
C. Defoliants
D. Growth regulators
Answer: B
Rationale: Fungicide seed treatments are used to suppress or control fungal
pathogens that attack seeds or seedlings. Common targets include damping-off
organisms, seed rots, and seedling blights caused by fungi.
6. Why is accurate pesticide dosage especially important in seed treatment
operations?
A. Seed treatments are always applied at higher rates than foliar sprays
B. Small differences in dosage can affect seed safety and pest control
C. The pesticide label does not specify seed rates
D. Excess pesticide improves germination in all crops
Answer: B
Rationale: Seed treatment rates are carefully calculated because seeds and
young seedlings are sensitive to pesticide exposure. Under-application may fail
to control pests, while excessive rates may reduce germination, damage
seedlings, or violate pesticide regulations.
7. The best way to prevent cross-contamination between different seed
treatment products is to:
, A. Use separate, properly cleaned equipment when required
B. Store all products in the same container
C. Mix all leftover products together
D. Avoid cleaning equipment between crops
Answer: A
Rationale: Cross-contamination can result in unintended pesticide exposure, crop
injury, and inaccurate applications. Proper equipment cleaning and appropriate
handling procedures prevent residues from one product affecting another seed
lot or crop.
8. Which factor most directly affects the accuracy of a seed treatment
application?
A. Seed color
B. Equipment calibration
C. Field slope
D. Crop marketing price
Answer: B
Rationale: Calibration ensures the equipment delivers the correct pesticide
amount per unit of seed. Incorrect calibration can result in under-treatment,
excessive chemical use, poor pest control, or seed damage.
9. Treated seed must be labeled or identified primarily because:
A. It improves seed appearance
B. It prevents accidental use as food or feed
C. It increases seed weight
D. It eliminates the need for storage precautions
Answer: B
