TURF (3B): TURF PEST MANAGEMENT -
TEST YOUR KNOWLEDGE EXAM 2025
QUESTIONS AND ANSWERS
Name some of the factors turfgrass managers must consider when setting pest management
priorities. - ANS Turfgrass management professionals must consider human safety,
environmental safety, turf use(s), efficacy, and economics.
Why do pest management thresholds in turf vary? - ANS Pest thresholds vary from site to
site because they depend on site characteristics and uses. For example, there may be zero
tolerance for pests of any sort on a gold green. On the other hand, there may be no great need
to control pests in the grassy areas of an industrial site. However, setting thresholds in some
sites - like a school athletic field or playground - may not be simple and clear-cut. A thick,
uniform surface is ideal for play areas, for optimum utility and safety. This, in turn, means the
tolerance for pests is low. However reliance on pesticide use may not be acceptable for some
recreational sites, especially if the primary users of that site are children.
What is the first, most basic step to take to manage pest problems? Explain your answer. -
ANS Use Best Management Practices (BMPs) for initial design, installation, and maintenance
programs. Begin by selecting high quality, disease- and insect-free turfgrass. When possible,
plant or install resistant varieties. Choosing the right variety for the site and use(s) is essential.
Next, good cultural practices provide the best conditions for plant health.
Why should you focus your attention on key pests, key varieties, or key locations? -
ANS They are most likely to cause problems. Key pests, varieties, and locations require
special monitoring and care.

, What is a "key pest"? - ANS A key pest is one that often reaches population densities that
justify management, and/or is capable of causing unacceptable damage at relatively low
densities, and/or attacks and damages turfgrass(es) in conspicuous or valuable areas.
What is a "key variety"? - ANS A "key variety" has a special "high profile" use. A variety that
sustains damage from pests on a regular basis, or has a particular pest that can kill or disfigure
it in low densities, would also be considered a "key variety."
Describe a site that would be considered a key location. - ANS Key locations are heavily used
or are significant in some way. Areas where turfgrasses have chronic problems with pests,
and/or areas that are near something or someone requiring special protection are "key
locations."
Name several things you need to make an accurate diagnosis of a pest problem. -
ANS Description of the type and extent of plant damage, identification of the pest, familiarity
with the life cycle of the pest, a good estimation of the size and distribution of the pest
population, and an assessment of whether it is increasing or decreasing.
Define the term "Integrated Pest Management." List IPM tactics used in turfgrass pest control. -
ANS Integrated Pest Management refers to the use of a combination of pest control tactics.
IPM programs use many types of techniques in a single plan or strategy to reduce pests and
keep their damage to an acceptable level. IPM tactics include monitoring and early detection,
sanitation, and cultural, mechanical (physical), biological, and chemical control methods.
What is biological control? Give one example. - ANS Biological control involves using some
aspect of the pest's biology to control it. One example is the uyse of natural enemies, biological
agents that control a pest. Turfgrass managers can preserve or encourage natural enemies
already present in the system. Alternatively, they can introduce commercially produced
biological organisms. Biological control also includes the use of pheromones or juvenile
hormones to control insects.
What are some factors that influence the success of biological controls? - ANS Biological
control agents usually target specific pests. Biological control agents must be able to move to -
or be placed in contact with - the target pest. For that reason, application techniques influence
success. Adoption of biological control measures usually takes careful planning and timing.
