Category 1: Pest Management
1. What is the primary goal of Integrated Pest Management (IPM)?
a) Eradication of all pests
b) Prophylactic application of pesticides
c) Prevention and suppression of pests with minimal environmental
impact
d) Using only biological controls
Answer: C. IPM is a sustainable approach that focuses on long-term
prevention and suppression through a combination of techniques like
biological control, habitat manipulation, and chemical control, with
pesticides used only as a last resort.
2. An action threshold is best defined as:
a) The number of pests a plant can tolerate without damage.
b) The point at which pest populations or environmental conditions
indicate that pest control action must be taken.
c) The legal limit of pesticide residue on food.
d) The maximum number of pests an area can support.
Answer: B. The action threshold is a critical IPM concept. It is the level at
which the pest population becomes an economic, aesthetic, or health
threat, justifying control measures.
3. Which of the following is an example of a cultural control practice?
a) Releasing ladybugs to eat aphids.
,b) Rotating crops to disrupt the life cycle of soil-borne pests.
c) Applying an insecticide.
d) Using pheromone traps to monitor insect populations.
Answer: B. Cultural controls involve modifying the environment or host
plant's condition to make it less hospitable to pests. Crop rotation is a
classic example.
4. Which pest management method uses pheromone traps?
a) Chemical Control
b) Biological Control
c) Mechanical Control
d) Genetic Control
Answer: C. Pheromone traps are a form of mechanical (or physical)
control. They physically trap or attract pests for monitoring or direct
control, disrupting mating without using a toxicant.
5. The "economic injury level" of a pest is the point where:
a) The pest is first noticed.
b) The cost of control equals the damage caused by the pest.
c) The cost of control equals the damage that will be caused by the
pest.
d) The pest population reaches its carrying capacity.
Answer: C. This is a precise definition. The economic injury level is a
theoretical point where the pest population density causes yield loss
equal in value to the cost of control measures.
Category 2: Federal Pesticide Law
,6. The primary federal law governing the registration and use of
pesticides in the United States is the:
a) Endangered Species Act
b) Occupational Safety and Health Act
c) Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
d) Food Quality Protection Act (FQPA)
Answer: C. FIFRA is the cornerstone of U.S. pesticide regulation,
administered by the EPA.
7. Under FIFRA, a "Restricted Use Pesticide" (RUP) is classified as such
because:
a) It is always more effective than a general use pesticide.
b) It is only for agricultural use.
c) It may cause unreasonable adverse effects to the environment or
the applicator without additional restrictions.
d) It is the cheapest option available.
Answer: C. RUPs require special handling and can only be applied by or
under the direct supervision of a certified applicator.
8. The Food Quality Protection Act (FQPA) of 1996 specifically
emphasized the protection of whom from pesticide risks?
a) Only adult farmers
b) Infants and children
c) Only endangered species
d) Aquatic organisms
*Answer: B. The FQPA mandated a new safety standard of "a
reasonable certainty of no harm" that explicitly required an additional
10x safety factor to account for pre- and post-natal toxicity and
completeness of data concerning children.*
, 9. It is illegal to use any pesticide in a manner inconsistent with its:
a) Advertising claims
b) Price
c) Labeling
d) Availability
Answer: C. This is the "use inconsistent with the labeling" provision of
FIFRA. The label is the law.
10. Who is ultimately responsible for the safety and legal application
of a pesticide?
a) The pesticide manufacturer
b) The landowner
c) The certified applicator
d) The state regulatory agency
text
*Answer: C. The certified applicator is legally responsible for ensuring
the application is safe, effective, and complies with all label instructions
and regulations.*
Category 3: Pesticide Labeling
11. The most reliable source of information for the safe and effective
use of a pesticide is the:
a) Pesticide dealer
b) University extension service
c) Product label
d) Safety Data Sheet (SDS)
