Name some of the factors turfgrass managers must consider when setting pest management
%%%%%%
priorities. - (ANSWERS)Turfgrass management professionals must consider human safety,
environmental safety, turf use(s), efficacy, and economics.
Why do pest management thresholds in turf vary? - (ANSWERS)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. -
(ANSWERS)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? -
(ANSWERS)They are most likely to cause problems. Key pests, varieties, and locations require
special monitoring and care.
What is a "key pest"? - (ANSWERS)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"? - (ANSWERS)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. - (ANSWERS)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. -
(ANSWERS)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. -
(ANSWERS)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. - (ANSWERS)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? -
(ANSWERS)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. Finally, biological control organisms must be able to tolerate
conditions at the site. To be sustainable, they must persist from season to season.
What is cultural control? List several cultural control tactics used in turf. - (ANSWERS)Cultural
control measures disrupt the normal relationship between pest and host in order to prevent or
suppress an infestation. Cultural controls make the pest less likely to survive, grow, or
reproduce. They can involve changing the turf grass environment or its physical condition.
Cultural control measures may also change the behavior of a pest. In turf, variety selection and
proper establishment are basic cultural control measures. Other practices employed in turf
include thatch management and proper mowing, watering, and fertilization regimes. Aerating
soil and cultivation practices that improve water infiltration (spiking, vertical mowing, or coring)
can help.
What is mechanical control? - (ANSWERS)Mechanical controls use some mechanical device
such as a trap or barrier to control pests.
What is sanitation? Give two examples. - (ANSWERS)Sanitation is general cleanliness.
Sanitation reduces the levels of pathogens and other pests in the turf grass environment. Using
pest-free seed, sprigs, or sod is a sanitation strategy. Careful disposal of diseased clippings is
another. So are cleaning and disinfecting tools and equipment, and taking care to avoid
spreading disease by foot traffic.
