and other recreational turf, parks, roadsides, airports, and cemeteries
The greatest segment of the industry Right Ans - home lawns
Turfgrass is maintained for: Right Ans - beautification, recreation, erosion
control, and general utility purposes
Most important factors in maintaining good turf and preventing problems
Right Ans - selecting the right grass, mowing, watering, fertilizing, and thatch
control
Pesticides should be used as an... Right Ans - aid in turf management but
not as a substitute for good cultural practices
Cool season grasses Right Ans - bluegrass, tall fescue, and ryegrass
Warm season grasses Right Ans - Bermudagrass, zoysia, and buffalograss
Process of diagnosing turfgrass problems Right Ans - - determine kind of
grasses involved
- find out why the problem occurred
- determine if the problem is best corrected by management practices, soil
modification, or pesticides
- check to see if a chemical is labeled both for the turfgrass species and the
problem
- recommend good cultural practices that will assist in turfgrass recovery
IPM Right Ans - (Integrated Pest Management) an effective and
environmentally sensitive approach to pest management that relies on a
combination of common-sense practices
uses current, comprehensive information on the life cycle of pests and their
interaction with the environment
, Four-tiered approach to IPM Right Ans - 1) set "economic" or "action
thresholds"
2) monitor and identify pests
3) prevention
4) control
"Economic" or "Action thresholds" Right Ans - a point at which pest

must be taken to prevent economic loss
Favorable pH of soils Right Ans - between 6 and 7 (neutral)
Turfgrasses are selected based on: Right Ans - - use
- growth environment (soil type, light, moisture)
- the desired appearance
- management level it will receive
- pest resistance
Turfgrass cultivars (varieties) Right Ans - species selected for specific
characteristics such as disease resistance, tolerance of unusual environments,
and appearance
Biological control Right Ans - use of bacteria, fungi, nematodes and
parasitic or predaceous insects to control pest organisms
Genetic control Right Ans - disease resistant cultivars
Prevention during planting Right Ans - use seed or sod and plugs that are
as pest free as possible
Pesticides are selected based on: Right Ans - - application method and
timing
- toxicity
- effectiveness
- host specificity
- cost
