1. What does cultivar mean? - Correct Answer: Variety of grass
2. What is economic injury level? - Correct Answer: Density of pests at
which damage to the turf will occur
3. What is economic threshold? - Correct Answer: Density of pests at
which the cost to manage the pest is equal to the losses that pest causes
4. What is action threshold? - Correct Answer: Pest density at which action
must be taken to prevent the pest from reaching the economic injury level
5. What are examples of cultural controls? - Correct Answer: Raking,
thatch removal, and aeration, most common is mowing
6. What are examples of mechanical and physical controls? - Correct
Answer: Hand removal, traps, repellents
,7. What is a mechanical and physical control? - Correct Answer: Tactics
that physically separate the pest from the host plant.
8. What is a biological control? - Correct Answer: Limit pests through
naturally occurring and introduced parasites and parasitoids, predators, and
diseases
9. What percent of lawns develop insect infestations that are bad enough to
require insecticides? - Correct Answer: 10%
10.What is a chemical control? - Correct Answer: Chemicals are used when
all other modes of pest control have been exhausted and a pest population
still exceeds the economic threshold
11.What is LD 50? - Correct Answer: The dose identified by the developer
of the pesticide that will kill 50% of the population of the species on which
the pesticide is tested.
12.What is a broad spectrum pesticide? - Correct Answer: Developed to
suppress a wide range of pests
13.What is a systematic pesticide? - Correct Answer: They are absorbed
into and travel within the pest plant
14.What type of plants use systematic pesticides? - Correct Answer:
Perennial weeds
,15.Why is it important to use both short term suppression and long term
maintenance tactics in pest management? - Correct Answer: Short term
suppression usually offers a quick fix, but the pest pop. will rebuild. Long
term maintenance must be used to reduce the pest pop. Permanently
16.The European Chafer cause damage in what type of turf? - Correct
Answer: In non irrigated, dry turf like home lawns
17.The Japanese beetle cause damage in what type of turf? - Correct
Answer: Irrigated turf
18.When should you use pesticides? - Correct Answer: As a last resort
when other options are ineffective or not practical
19.What is biomagnification? - Correct Answer: turf is unsafe for predatory
insects for a much longer time than it is for the pests against which the
insecticide was applied
20.True or False: IPM programs are the most effective and least hazardous way
to manage pests. - Correct Answer: True
21.What are degree days? - Correct Answer: Development of plants and
pests begins when the air reaches a certain base temperature and
continues at a rate prop. to air and soil temp
, 22.Define plant resistance - Correct Answer: Varieties of grass containing
endophyte fungi are one example
23.What is an example of a turf grass disease that can be managed with hand
removal techniques? - Correct Answer: Slime mold
24.What is an example of a weed situation that can be managed with hand
removal techniques? - Correct Answer: In a new stand of grass, used to
prevent damage to the young grass plants
25.Why can't turf at the same time benefit from biological control methods
and be pest free? - Correct Answer: There must be a low level of pest or
prey insects for the predators to feed on.
26.How can you help maintain existing populations of beneficial organisms in a
turf stand? - Correct Answer: By making pesticide applications only
when needed
27.What is the most commonly used microbial insecticide - Correct
Answer: Bacillus thuringiensis to control caterpillars
28.Are microbial insecticides best used for short term suppression or long term
maintenance? - Correct Answer: Long term maintenance
29.What are 4 ways to classify pesticides - Correct Answer: 1. Types of pest
