1. Which of the following best describes Integrated Pest Management (IPM)?
A. Using only chemical pesticides for pest control
B. Eliminating all insects regardless of species
C. Combining cultural, biological, and chemical control methods to
manage pests
D. Ignoring minor pest infestations
Rationale: IPM emphasizes a combination of preventive, biological, and
chemical strategies to manage pests sustainably and economically.
2. When applying herbicides to a landscape, the primary reason for using a
surfactant is to:
A. Increase evaporation of the herbicide
B. Reduce soil absorption of the herbicide
C. Improve adhesion and penetration of the herbicide on plant surfaces
D. Change the pH of the solution
Rationale: Surfactants lower surface tension, allowing herbicides to spread
evenly and penetrate plant tissues for effective control.
3. Which of the following insects is classified as a chewing pest in turfgrass
management?
A. Aphids
, B. White grubs
C. Spider mites
D. Scale insects
Rationale: White grubs feed on roots, damaging turf by chewing, unlike sap-
sucking pests like aphids or mites.
4. In landscape pest control, the most common route of pesticide exposure for
applicators is:
A. Ingestion through food
B. Dermal contact
C. Inhalation from aerosol drift only
D. Injection via plant material
Rationale: Dermal contact is the primary exposure route during mixing, loading,
and applying pesticides, making protective clothing essential.
5. A homeowner reports yellowing and wilting of shrubs following a recent
herbicide application. Which of the following is the most likely cause?
A. Fungal infection
B. Herbicide drift from neighboring area
C. Overwatering
D. Nutrient deficiency
Rationale: Symptoms often occur due to non-target herbicide exposure via drift
or misapplication, especially in sensitive plants.
6. Which of the following best defines the term “pest threshold”?
A. The legal limit for pesticide application
, B. The maximum number of pesticides allowed per site
C. The level of pest activity at which action must be taken to prevent
economic or aesthetic damage
D. The number of pest species present in an area
Rationale: Pest thresholds guide management decisions to avoid unnecessary
pesticide use and reduce environmental impact.
7. Which soil factor most affects the persistence of a systemic herbicide?
A. Temperature only
B. Organic matter content
C. Sunlight exposure
D. Soil pH only
Rationale: Organic matter binds herbicides, affecting their availability,
persistence, and potential movement in soil.
8. Which of the following is considered a biological control agent?
A. Glyphosate
B. Lady beetles
C. Malathion
D. Atrazine
Rationale: Biological control involves using living organisms like predators,
parasites, or pathogens to reduce pest populations.
9. For turfgrass grub management, which timing strategy is most effective?
A. Late summer before eggs hatch
B. Early spring after adults emerge
, C. Late summer when larvae are small and feeding near the soil surface
D. Winter during dormancy
Rationale: Grub control is most effective when larvae are small and close to the
soil surface, as they are more susceptible to insecticides.
10.When mixing two pesticides, the label recommends conducting a jar test.
This is done to:
A. Increase chemical effectiveness
B. Check compatibility to prevent chemical reactions or precipitation
C. Measure soil absorption
D. Improve spray coverage
Rationale: A jar test ensures the two chemicals can be safely mixed without
forming clumps, reducing the risk of equipment damage or reduced efficacy.
11.Which statement about pesticide storage is correct?
A. Store pesticides near food for easy access
B. Store pesticides in a cool, dry, well-ventilated area away from
children and pets
C. Store in direct sunlight to prevent freezing
D. Keep containers open for air circulation
Rationale: Proper storage prevents accidental exposure, degradation, and
contamination.
12.Which of the following weeds is a perennial broadleaf?
A. Crabgrass
B. Dandelion
