QUESTIONS AND ANSWERS

Question 1 Which of the following lists four of the available methods to control pests when natural controls are not sufficient?

• Genetic mutation, radiation, companion planting, and hand-picking
• Host resistance, biological control, mechanical control, and chemical control
• Fertilization, pruning, crop rotation, and harvesting
• Solarization, flooding, burning, and vacuuming

Correct Answer: B) Host resistance, biological control, mechanical control, and

chemical control

Question 2 What are the four factors that affect pesticide use outdoors?

• Lunar phases, altitude, plant height, and insect migration
• Cloud cover, atmospheric pressure, soil pH, and daylight hours
• Soil factors, surface moisture, humidity and temperature, and wind
• Pesticide brand, container size, water source, and application speed

Correct Answer: C) Soil factors, surface moisture, humidity and temperature,

and wind

• | P a g e

Question 3 What is the best method for controlling plant diseases?

• High-volume chemical spraying
• Prevention
• Introducing biological predators
• Mechanical removal of roots

Correct Answer: B) Prevention

Question 4 Which of the following represents forms of mechanical vertebrate pest control?

• Systemic poisons, baits, and biological pathogens
• Crop rotation, sanitation, and host resistance
• Desiccants, defoliants, and plant growth regulators
• Traps, barriers, gunning, attractants, and repellents

Correct Answer: D) Traps, barriers, gunning, attractants, and repellents

Question 5 What is a pesticide formulation?

• The exact application rate required by law
• The mixture of active and inert (inactive) ingredients that forms a pesticide

product

• The chemical structure of the active ingredient only
• The process of mixing a pesticide with water in a spray tank

Correct Answer: B) The mixture of active and inert (inactive) ingredients that

forms a pesticide product

Question 6

How can pest identification help you develop a good pest control strategy?

• It helps you determine basic information, including the pest's life cycle and

the time it is most susceptible to being controlled

• It allows you to bypass EPA label requirements for application
• It dictates the specific brand name of the pesticide you must purchase
• It guarantees that a single pesticide application will permanently eradicate

the pest

Correct Answer: A) It helps you determine basic information, including the

pest's life cycle and the time it is most susceptible to being controlled

Question 7 What is the definition of "integrated pest management" (IPM)?

• The exclusive use of natural predators to eliminate pest populations
• The combining of appropriate pest control tactics into a single plan to reduce

pests and their damage to an acceptable level

• The maximum application of chemical pesticides to ensure complete

eradication

• The legal framework established by the EPA for pesticide registration

Correct Answer: B) The combining of appropriate pest control tactics into a

single plan to reduce pests and their damage to an acceptable level

Question 8 If you applied a pesticide but it did not control the pest, what are three possible reasons for the failure?

• The product was too fresh, applied at night, or the soil was too rich
• Pest resistance, choosing the wrong pesticide, or misidentifying the pest
• Using a granular formulation, mixing with too much water, or applying in

direct sunlight

• | P a g e

• The pest migrated, the plant absorbed the chemical, or the container was

plastic

Correct Answer: B) Pest resistance, choosing the wrong pesticide, or

misidentifying the pest

Question 9 What can you do to keep the pests you are trying to control from becoming resistant to the pesticides you use?

• Apply a higher concentration of the same pesticide each time
• Apply pesticides on a daily schedule regardless of pest presence
• Mix all available pesticides together into a single tank mix
• Use integrated pest management and rotate the types of pesticides used

Correct Answer: D) Use integrated pest management and rotate the types of

pesticides used

Question 10 What is the difference between active ingredients and inert ingredients?

• Active ingredients are synthetic chemicals, while inert ingredients are

naturally occurring substances

• Active ingredients control pests, while inert ingredients are added to make

the product safer, more effective, and easier to handle

• Active ingredients are used for insect control, while inert ingredients are

used for weed control

• Active ingredients require a license to handle, while inert ingredients are

unregulated Correct Answer: B) Active ingredients control pests, while inert ingredients are added to make the product safer, more effective, and easier to handle
