1. What is the primary purpose of integrated pest management (IPM) in
landscape maintenance?
a. To completely eliminate all pests
b. To reduce pest populations to acceptable levels **
c. To replace chemical control with mechanical control only
d. To increase pesticide use efficiency
Rationale: IPM focuses on managing pest populations to levels that do not
cause economic or aesthetic damage, using a combination of methods.
, 2. Which of the following is the most common method of spreading
fertilizers in landscape maintenance?
a. Injection
b. Foliar spray
c. Broadcast application **
d. Soil fumigation
Rationale: Broadcast application distributes fertilizer evenly over the soil
surface and is commonly used in lawns and landscapes.
3. When applying granular pesticides, which factor is most critical to
avoid runoff?
a. Wind speed **
b. Sunlight
c. Temperature
d. Soil pH
Rationale: Wind can carry granules off target, leading to drift and runoff;
controlling application during calm conditions is critical.
4. Which type of herbicide is absorbed through leaves and translocated
throughout the plant?
a. Contact herbicide
b. Systemic herbicide **
, c. Preemergent herbicide
d. Residual herbicide
Rationale: Systemic herbicides move within the plant tissue, killing the

5. When should personal protective equipment (PPE) be worn during
pesticide application?
a. Only when mixing chemicals
b. Only when applying liquid pesticides
c. Always, as specified on the label **
d. Only during post-application cleanup
Rationale: PPE must be used whenever the label indicates to reduce
exposure and protect the applicator.
6. Which factor has the greatest influence on pesticide drift?
a. Temperature
b. Wind speed and direction **
c. Application rate
d. Equipment type
Rationale: Wind is the primary factor causing off-target drift; applicators
must monitor wind conditions.
, 7. What is the main advantage of using mulch in landscape
maintenance?
a. Enhances pesticide absorption
b. Reduces water evaporation and soil erosion **
c. Increases soil compaction
d. Promotes weed growth
Rationale: Mulch helps conserve soil moisture, suppress weeds, and
prevent erosion.
8. Which of the following is a common sign of overwatering in turfgrass?
a. Wilting
b. Yellowing leaves **
c. Stunted growth
d. Early flowering
Rationale: Overwatering can lead to nutrient leaching and yellowing due
to root oxygen deficiency.
9. What is the most effective method to control invasive perennial weeds
in a landscape?
a. Repeated mowing
b. Hand-pulling once
