3A TURFGRASS PEST MANAGEMENT
ASSESSMENT QUESTIONS 2026 CORRECT
ANSWERS CONFIRMED
◍ What are the five turfgrass IPM steps? Answer: 1. Detect the pest
2. Identify the pest
3. Determine the amount of damage and whether it is below or above
tolerance threshold
4. Select and use a management tactic
5. Evaluate the effectiveness of the strategy and keep records.
◍ Visual inspection, coffee can technique, white paper test, root
sampling, disclosing solutions, pitfall traps, and pheromone-bait traps
are examples of what? Answer: Monitoring techniques
◍ Why is it better to keep track of degree day accumulations instead
of calendar days? Answer: Both plant growth and pest development
depend on the amount of heat that surrounds an organism.
◍ An organism shouldn't be classified and treated as this until it is
proven to be one. Most species of insects, fungi, nematodes and
bacteria are either harmless or beneficial to turf. Answer: Pest
,◍ Many of these are directly associated with a specific species or
cultivar (variety) of grass. Knowing the cultivar growing in a
particular area may help you diagnose the problem. Answer: Turfgrass
disorder
◍ This is defined as the density of pests at which damage to the turf
will occur. Answer: Economic injury level (EIL)
◍ This is the pest density at which action must be taken to prevent the
pest from reaching the economic injury level. Answer: Action
threshold
◍ What are:
1. Client's tolerance of pest damage
2. Visibility or use of the turn stand
3. Level of maintenance
4. Health and vigor of the turf stand
5. The degree of risk from the pest injury to the plant host
6. Expected pest reduction by natural controls Answer: Factors
affecting turfgrass injury level
◍ What are the two types of pest management tactics? Answer:
immediate, short-term suppression and long-term maintenance
◍ Some species or cultivars of grasses are resistant to damaging pests
because of these that live inside grass plants. These produce
, chemicals in the plant that provide resistance to some pests. Answer:
Endophytic fungi
◍ This control type includes raking, thatch removal and aeration.
Routing maintenance practices such as moving, fertilizing and
irrigating are important. Answer: Cultural control
◍ This control method are tactics that physically separate the pest
from the host plant. Examples include hand-removal, traps, barriers
and repellents. Answer: Mechanical and physical controls
◍ This is an example of a disease that you can readily control by
physically removing it. Answer: Slime mold
◍ This method isn't practical to manage weeds in established turf,
however, it may be the only appropriate weed control operation for
newly plant stands of tender grass. Answer: Hand-removal
◍ A pest stand cannot be both: Answer: pest-free and benefit from
biological control
◍ This natural microbial insecticide product kills many insect larvae,
including armyworms, cutworms, sod webworms, and other
catepillars. Answer: Bacillus thuringiensis or Bt
◍ Pesticides are typically classified in four ways: Answer: 1. Type of
pest controlled
