1. The primary goal of integrated pest management (IPM) in ornamental and
turf pest control is to:
A. Eliminate all insects from the landscape regardless of species
B. Apply pesticides on a fixed calendar schedule
C. Manage pests effectively while minimizing risks to people, plants, and the
environment
D. Use only synthetic pesticides for maximum control
Answer: C
Rationale: IPM is a comprehensive pest management strategy that combines
monitoring, identification, cultural practices, biological controls, and carefully
selected pesticide applications when necessary. The goal is not complete
eradication of all organisms but maintaining pest populations below damaging
levels while reducing unnecessary pesticide use and environmental impact.
2. Before applying a pesticide to an ornamental plant, the applicator should
first:
A. Increase the application rate to ensure control
B. Correctly identify the pest and determine whether treatment is necessary
,C. Mix multiple pesticides together for broader control
D. Apply the pesticide immediately when damage is observed
Answer: B
Rationale: Proper pest identification is essential because many plant problems
are caused by diseases, nutrient deficiencies, environmental stress, or non-pest
factors. Applying pesticides without confirming the pest can waste money, harm
beneficial organisms, and fail to solve the problem.
3. A pesticide label states that a product may be applied only to established
turf areas. Which situation would violate the label?
A. Applying the product to mature athletic fields
B. Applying the product to a maintained lawn
C. Applying the product according to the labeled rate
D. Applying the product to newly seeded turf when establishment is not
complete
Answer: D
Rationale: The pesticide label is a legal document that specifies where, when,
and how a product may be used. Applying a product to a site not listed on the
label, such as newly seeded turf when prohibited, is a violation and may cause
injury or regulatory action.
4. Which pest category includes organisms such as aphids, scales, and
whiteflies?
A. Sucking insects
B. Soil pathogens
C. Vertebrate pests
D. Turf diseases
Answer: A
,Rationale: Aphids, scales, and whiteflies are classified as sucking insects because
they feed by piercing plant tissues and removing plant fluids. Their feeding can
cause yellowing, wilting, distorted growth, and sometimes transmission of plant
diseases.
5. A turf manager notices irregular brown patches in a lawn. Before applying a
fungicide, the applicator should:
A. Apply the highest labeled rate immediately
B. Treat the entire property preventively
C. Determine whether the symptoms are caused by a disease rather than
environmental stress or cultural problems
D. Mix fungicide with fertilizer for improved performance
Answer: C
Rationale: Turf damage can result from many causes, including drought stress,
improper mowing, soil compaction, insects, and diseases. Correct diagnosis
prevents unnecessary fungicide applications and allows the applicator to select
the proper management approach.
6. Which environmental condition most increases the risk of pesticide drift
during application?
A. Low wind speeds with moderate humidity
B. High wind speeds combined with small spray droplets
C. Cool temperatures and calm conditions
D. Large droplets applied close to the target
Answer: B
Rationale: Spray drift occurs when pesticide droplets or vapors move away from
the intended treatment area. High winds and small droplets increase the
, likelihood that pesticides will travel off target, potentially affecting sensitive
plants, water resources, wildlife, or people.
7. The pesticide label rate is usually expressed as:
A. The maximum amount an applicator can legally own
B. The amount needed to kill every organism in the area
C. The amount that guarantees no resistance development
D. The amount required to achieve effective control when applied correctly
Answer: D
Rationale: Label rates are established through research to provide effective pest
control while reducing risks of plant injury, environmental contamination, and
unnecessary pesticide exposure. Applying more than the labeled rate is illegal
and may cause harmful effects.
8. Which practice helps reduce pesticide resistance in ornamental and turf
pests?
A. Rotating pesticides with different modes of action
B. Using the same pesticide repeatedly throughout the season
C. Applying pesticides at lower-than-labeled rates
D. Treating without identifying the pest
Answer: A
Rationale: Repeated use of pesticides with the same mode of action can select
for resistant pest populations. Rotating products with different modes of action
and combining chemical control with IPM practices helps preserve pesticide
effectiveness.

applications are determined primarily by:
