3A TURFGRASS PEST MANAGEMENT EXAM LATEST 2023-2024 REAL EXAM 200+ QUESTIONS AND
CORRECT ANSWERS
Varieties of grass containing endophyte fungi are an example of: - (answer) Plant resistance.
Raking, thatch removal and aeration are examples of: - (answer) Cultural controls.
Hand removal, traps, barriers and repellents are examples of: - (answer) Mechanical and physical
controls.
Example of a turfgrass disease that can be managed with hand removal techniques: - (answer) Slime
mold.
Turf cannot at the same time benefit from biological control methods and be pest free because: -
(answer) There must be a low level of pest or prey insects for the predators to feed on.
Why is it important to use both short term suppression and long term maintenance tactics in pest
management? - (answer) Usually offers a quick fix, but the pest population will rebuild. Maintenance
must be used to reduce pest populations permanently.
How can you help maintain existing populations of beneficial organisms in a turf stand? - (answer) By
making pesticide applications only when needed.
What is the most commonly used microbial insecticide? On what insect larvae is it effective? - (answer)
Bacillus thuringiensis, or Bt, used to control caterpillars.
Are microbial insecticides best used for short or long term suppression of pest populations? - (answer)
Long term. Microbial insecticides are slower acting and do not kill all of the pests at once, which allows
there to be food for other beneficial organisms.
Ways to classify pesticides: - (answer) Types of pests
Pesticide chemistry

CORRECT ANSWERS
Mode of action
Pesticide formulation.
Benefits of systemic herbicides: - (answer) Superior in treating persistent perennial weeds, kills both
above ground and below ground parts of plant.
Benefits of broad spectrum pesticides: - (answer) Can be used to control several pests, but more likely
to be hazardous to non target organisms.
Benefits of residual pesticides: - (answer) Good for use when the goal is to reduce the number of
applications required to control persistent pests.
Benefits of contact herbicides: - (answer) Does not kill the underground parts of plant.
Basic principles of managing pests in turfgrass: - (answer) Produce healthy plants that can reduce or
better tolerate pest attack
Identify what is damaging the turf
Expect some pests and tolerate some damage
Using pesticides as a last resort.
Steps of IPM for turfgrass: - (answer) Detect pest

CORRECT ANSWERS
Select and use a management tactic
Evaluate the effectiveness of the strategy and keep records.
Methods for monitoring and detecting turfgrass pests: - (answer) Visually
Coffee can flush
White paper test
Root sampling
Disclosing solution
Explain why keeping track of degree day accumulations is more useful for monitoring pest activity than
going by calendar dates: - (answer) Insects, diseases and weeds develop based on heat units. The
accumulation of heat units varies from year to year.
Explain how knowing the species or variety of turfgrass in a stand can help in pest diagnosis: - (answer)
Certain diseases and insect pests will affect certain species of turfgrass and will not affect others.
Economic injury threshold: - (answer) The density of pests at which the cost to manage the pest is
equal to the losses caused by that pest.
Action threshold: - (answer) The pest density at which action must be taken to prevent the pest from
reaching the economic injury level.
Factors influencing the economic injury level: - (answer) The client's tolerance for damage.
