management program?
A. Eliminate all insects permanently
B. Increase fertilizer use
C. Maintain healthy ornamental plants while minimizing pest damage
through integrated management
D. Water plants daily regardless of weather
Rationale: The purpose of ornamental pest management is to maintain
attractive, healthy plants using Integrated Pest Management (IPM),
which combines cultural, biological, mechanical, and chemical controls
while minimizing environmental impact and unnecessary pesticide
applications.
2. Which component is considered the foundation of an Integrated
Pest Management (IPM) program?
,A. Weekly insecticide spraying
B. Fertilization
C. Accurate pest identification
D. Irrigation scheduling
Rationale: Correct identification of pests is essential because different
pests require different management strategies. Misidentification can
result in ineffective control, wasted resources, and unnecessary
pesticide use.
3. Before applying a pesticide to ornamental plants, the applicator
should first:
A. Mix the highest labeled rate
B. Spray during the hottest part of the day
C. Read and follow the pesticide label
D. Water the plants immediately after spraying
Rationale: The pesticide label is a legal document that provides
directions for safe and effective use, including application rates,
protective equipment, environmental precautions, and restrictions.
4. Which insect has piercing-sucking mouthparts?
A. Japanese beetle
B. Caterpillar
,C. Aphid
D. Sawfly larva

A. Root decay
B. A black fungal coating that reduces photosynthesis
C. Stem cankers
D. Leaf blight
Rationale: Sooty mold grows on honeydew deposits, covering leaves
with a black coating that blocks sunlight and reduces photosynthesis
without directly infecting plant tissue.

feeding damage?
A. Egg
B. Adult
C. Pupa
D. Larva
Rationale: Caterpillars are the feeding stage of butterflies and moths
and consume large amounts of foliage before pupating.
8. The presence of stippling or tiny yellow spots on leaves often
indicates infestation by:
A. Slugs
B. Beetles
C. Spider mites
D. Cutworms
Rationale: Spider mites puncture plant cells and remove contents,
leaving tiny yellow or white stipples that eventually merge into bronzed
foliage.
