1. Which of the following is the primary purpose of integrated pest
management (IPM) in ornamental and turf settings?
A. Eliminate all pests immediately
B. Rely solely on chemical control
C. Combine cultural, biological, and chemical strategies to
manage pests
D. Focus only on aesthetic appearance
Rationale: IPM emphasizes a combination of strategies—cultural,
biological, and chemical—aimed at long-term pest management while
minimizing environmental impact.
2. What is the most common vector for spreading fungal diseases in
turfgrass?
, A. Airborne spores
B. Water and irrigation systems
C. Soil nematodes
D. Birds
Rationale: Many turfgrass fungal diseases are spread via splashing
water from irrigation or rainfall, making proper irrigation management
crucial.
3. Which turfgrass species is best adapted to southern Alabama
landscapes with high heat tolerance?
A. Kentucky bluegrass
B. Bermudagrass
C. Perennial ryegrass
D. Fine fescue
Rationale: Bermudagrass is highly heat- and drought-tolerant, making it
ideal for southern U.S. climates, including Alabama.
4. When applying a systemic insecticide to ornamental plants, the
most effective method is:
A. Foliar spray only
B. Soil drench or injection
C. Broadcast granular application
D. Surface dusting
,Rationale: Systemic insecticides are absorbed by roots and transported
throughout the plant, making soil drench or injection more effective
than surface applications.
5. Which of the following is considered a pre-emergent herbicide
use?
A. Killing existing weeds after they emerge
B. Fertilizing turf to enhance growth
C. Preventing weed seeds from germinating
D. Watering newly planted grass

before they sprout, providing preventative weed control.
6. Which insect is a common pest of ornamentals and is
characterized by sucking plant sap and excreting honeydew?

B. Aphids
C. Grubs
D. Leaf miners
Rationale: Aphids feed on plant sap and produce honeydew, which can
promote sooty mold and attract ants.
7. When is the best time to apply fungicides for control of foliar
diseases in ornamentals?
, A. Before symptoms appear or at early stages of infection
B. Only after severe infection
C. During leaf drop
D. Only in winter
Rationale: Fungicides are most effective when applied preventatively or
at early disease development rather than after significant infection has
occurred.
8. What is the primary purpose of a surfactant in a pesticide
formulation?
A. Increase toxicity
B. Reduce cost
C. Improve coverage and adhesion of pesticide on plant surfaces
D. Neutralize soil pH
Rationale: Surfactants reduce surface tension of sprays, helping
pesticide droplets spread and stick to plant surfaces for better
effectiveness.
9. Which of the following is a common symptom of nematode
damage in turf?
A. Yellowing leaves only
B. Thin, patchy turf with stunted root systems
